I’ve recently developed a new habit that’s become a key part of my daily routine: eating two small pastry bites before my morning run and four while mowing the lawn. This might seem like a quirky ritual, but for someone like me, living with chronic kidney disease, it’s actually a carefully considered strategy. My condition requires me to follow a highly controlled diet, which means that many of the foods others enjoy freely are off-limits or need to be consumed in minimal quantities. For example, I have to be extremely cautious with my protein, cheese, and chocolate intake—three things I used to enjoy but now have to ration carefully.
But those are just the tip of the iceberg. There are many other foods that I need to monitor closely, especially when it comes to salt. Salt is a concern because it’s hidden in many everyday items, like bread. Many of the bread on store shelves contain far more salt than my kidneys can safely handle, so I’ve had to say goodbye to many of my old favorites.
When we first discovered my kidney disease, it was a wake-up call that prompted significant changes in our household. Dining out, for example, became a rare occasion—something we now do no more than once a week, if at all. We also became much more vigilant about what we bring into our kitchen. Spice mixes, which often contain hidden salt, are a perfect example. My wife began making our spice blends and sauces from scratch each weekend to avoid this. This way, we can ensure that everything we eat is within my dietary guidelines. While this may sound like a lot of work, we ease into it gradually, making it feel like a natural part of our lifestyle rather than a burden.
Summer, of course, brings its own challenges, particularly with the added task of lawn care. Because of my dietary restrictions, I used to rely on small, plant-based protein bars to keep my energy up during these activities. My doctor assured me these were safe in moderation, but I might have overdone it. I soon realized that I needed to cut back on them, which led to a new problem: maintaining my weight. My weight tends to hover between 145 and 155 pounds, and according to my smart scale, I have more muscle than the average person my age, thanks to regular exercise. However, with so little body fat, any drop in weight likely means I’m losing muscle, which isn’t ideal.
To tackle this issue, my wife turned to the DaVita website, a resource we’ve trusted since my time on peritoneal dialysis. DaVita specializes in kidney care and offers a wealth of kidney-friendly recipes. We found some great ideas there and decided to start making small muffins or pastry bites. These are perfect for my needs because they’re made in small portions, which means that eating a few won’t cause my blood sugar to spike, especially when I’m active. The pastry bites are filled with jam that my wife makes herself, using fresh fruit from the farmer’s market and just a touch of sugar. Store-bought jams are often too sweet for us, so this homemade version is a better fit.
Since I started incorporating these pastry bites into my diet, my weight has stabilized, and I’m no longer worried about muscle loss. I may need to adjust this routine when the lawn mowing season ends, but for now, eating two pastry bites before my run and four.
To improve my physical and mental condition, I decided to work on changing my lifestyle. I started with dancing Zumba on my switch, and I gradually made changes. My goal is to lose weight without losing my muscle mass. I implemented formal strength training offered by Les Mills into my exercise program in June. I have been exercising mindful eating for the last few months. Since the rate of losing weight was so slow, I decided to switch back to the calorie restriction. I started with creating 500 calories deficit per week.

HIIT (High-Intensity Interval Training) – 17minutes training – generates 40-45 minutes of activity minutes
The biggest change I did this time was creating 400-500 calories deficits per day to lose weight. I lost a total weight of 4.4lb. (2.8lb, 1.4lb, 0.2, 0.2lb) over the four weeks. I also lost 0.6lb of muscles mass (-0.6, -0.2, 0, +0.2). I lost 2.8lb; however, I also lost 0.6lb of muscle mass. So, I changed my tactic immediately as I am eating too little for the activities level. In the 2nd week, I ate 1,300 calories per day, resulting in muscle loss of 0.2lb. So, I adjusted my calories intake to 1,400 – 1,500 per day, which stopped my muscle loss. I could not measure the muscle mass of the 4th week due to a technical issue with my phone app.
Analysis
If my primary goal were to lose weight, I would have been happy about the result. In reality, I was shocked by the loss of muscle mass from the first week. I have been working hard to gain muscle by doing strength exercises and yoga three times per week.
My immediate reaction was to investigate how much I must eat not to lose my muscle mass. With my level of activities, getting 1,200 -1,300 calories per day was too little. At least I know that 1,400 calories are my current floor for my calorie intake.
I felt a little lightheaded in the first week because I was not eating enough food. Since I was so hungry at night, and I had difficulties falling asleep at night. As a result, my sleep quality dropped. Increasing the calories intakes by 100 calories did not stop muscle loss or sleep quality problems. Rising to 1,400 calories stopped the issues. At least I know that 1,400 calories are my current floor for my calorie intake. The minimum calories intake changes with the muscle mass; therefore, regular monitoring is essential.
Technical Problems
During the 2nd day of the 4th week, my 4-year-old smartphone stopped uploading my digital weight. The only measurement I can take is weight. Therefore, I expect some challenges in controlling and monitoring. I ordered a new phone, and I should have a new smartphone by September 12th. Since I can no longer watch my muscle mass, I must maintain 1,400 – 1,500 Calories per day with the same exercise routine.
Expectation Gaps
I lost weight; however, I was not happy with the result because I lost muscle mass. I conclude what I want is not to lose weight. To discover the output I want, I decided to organize my thoughts.
What I want to Happen:
I want to lose FAT %. My aim is 25% for the moment. I want to fit into my clothing.
I want to increase my muscle mass to increase my metabolisms and muscle strengths. (Strong).
I want to lose weight.
I want to improve my cardio endurance.
I want to increase flexibility.
I want to decrease my stress.
GAP Analysis
With the five items I listed, I care a lot about retaining or increasing my muscle mass. There are multiple reasons why I want to maintain my muscles. Exercise promotes muscle gains, which helps to prevent diabetes and to improve metabolism (McPherron, Guo, Bond, Gavrilova, 2013). I enjoy many outdoor activities, and retaining my muscles is the key to sustain these activities I enjoy. Moderate exercise can prevent Aging. Naturally, we tend to lose muscle mass as we age. We can prevent muscle loss by doing adequate exercises. I wanted the first two items the most. Mathematically if I increase my muscle mass, I should lose my fat percentage. Thus, I think these goals can coexist easily.
The amount of calorie input is a key to recent unnecessary loss in muscles. In the results from this round, I noticed that eating less than 1,200 calories made my weight decrease. I also lost fat mass. After two weeks, I had to make immediate changes since I did not want to lose any more muscle. I increased to 1,400 – 1,500 calories which seems to prevent me from losing muscle mass; however, the rate of weight loss will slow.
Conclusions
I learned an important lesson. Do not rush my weight loss because I can lose muscle mass. Furthermore, I felt lightheaded, and I had no energy with only 1,200 calories. My muscle loss stopped at 1,400 calories. I seem to have enough energy and a clearer head. Therefore, my current minimum calories intake is 1,400 calories.
Due to technical issues, I do not have the tools to monitor my muscle mass until the 2nd week of September. Thus, I decided to maintain my current programs.

When you know there are some expectation gaps, it will be good to organize your thoughts. For this round, I realize that I want to gain muscle and lose fat. Those measurements will be my primary monitoring inputs. I continue monitoring my total weight. Regular monitoring activities are crucial so that you can create timely corrective actions. The important thing is that I am improving little by little.

For the last few weeks, I changed my workout time to the early morning, 5:30 AM. On day one of the new exercise programs, I felt all workout routines feel much more challenging than when I do them at lunchtime or early evening.
Since I did not have a good sleep that day, I thought I was just tired. The following day, I did a cardio, BODYATTACK. I felt so pitiful that it was near impossible to bring my heart rate above 140 in the early morning than later in the day. I had 8.5 hours of sleep with a sleep score of 90 the day. So, it was nothing to do with the duration or quality of the sleep. I was curious about this phenomenon, so I continued the morning exercises every single day of the rest of the week and monitored my heart rates. I made changes to the intended exercise, but I wanted to check them all. So, I tried30 minutes BODYCOMBAT (Kickboxing), BODYATTACK (Bootcamp), BODYPUMP (Strength exercise), and GRIT (HIIT).
When I wake up, my heart rate is about 65. Usually, I move around the house for 15-20 minutes before exercising. The interesting part of this morning exercise was that I still felt as if I exercised at 90% of my max heart rate at the actual heart rate is just 135-140. GRIT was the worst one, and I had to give up at 17 minutes. Consequently, my calories output was lower by 100 calories for morning cardio exercises.
After one week of the observation, I made the following hypotheses.
The morning exercise feel harder because
My starting heart rate is lower in the morning. I suspect that that is something to do with my heart rate being so low in the early morning. My resting heart rate is 63-65, and it can be a lot of stress to push it up to almost double.
Since I am on intermittent fasting, my body does not have energy in the morning. I exercised at lunch during the fasting before. I have no problem reaching 90% of my max heart. Thus, the 2nd hypothesis is incorrect.
My muscles are not ready for a workout. I felt this when I was doing BODYPUMP (Strength Exercise) and GRIT (HIIT). I had difficulties keep my squats low.
I suspect that that is something to do with lower heart rates and stiffer muscles. Since my starting heart rate is so low, it can be a lot of stress to push it up to almost double in a short time. Interesting, right? I put my researcher’s hat on, and I investigated some.
If the primary objective is to have the best performance, the morning is not the right time to exercise.
As I suspected, the primary reason is the lower max heart rates in the morning. Thomas Reilly and his colleagues at the Research Institute for Sport and Exercise Sciences at Liverpool John Moore University (as cited in the New York Times, Dec 9, 2009) found that our maximum heart rate is lower in the morning. However, the perception of how hard they were working was the same for morning and evening. Our body has a circadian rhythm that controls the hormones in our body to have a regular sleep-wake schedule. Our blood pressure, metabolism, energy level, and heart rates are lower in the early morning.
He and his colleagues also mentioned that our bodies are not as well prepared to exercise in the morning because our muscles tend to be less flexible. The athlete’s best performance is set in the late afternoon or the early evening (as cited in the New York Times, Dec 9, 2009).
Is morning exercise being all that bad? Despite my findings, there are some benefits to exercising in the morning.
Dietary Choices for the day
The people who work out in the morning tend to make healthier food choices for the day. After observing 2,680 young adults for 15-week cardio exercise in the morning, the young adults who work out in the morning tend to pursue healthier dietary preferences and habits (Joo, Willamson, Vazquez, Fernandez, and Bray, 2018). The study did not particularly seek to find the best time to exercise; however, the morning exercise motivated them to make healthier eating throughout the day. Since I started the training in the morning, I feel it has gotten easier to regulate my foods intake for the day.
More energy and higher productivity
I felt dreadful during my morning workout; however, I felt more energy when I did the morning exercises. My heart rate is higher after the training. My body is warmer. I even felt more alert and focused on my work. I usually do 1 hour of continuing education in the morning. I noticed my focus was higher after the morning exercise. The best part was I felt so good the whole day because I did a workout in the morning. So, I was more productive.
The choice is all about what you want to accomplish and your preference.
I prefer to work out in the morning because I must go to bed early at night. I have never liked to wake up early; however, I hated the morning traffic even more than waking early in the morning. For the last year, I have been working remotely. My work would like me to go to the office three times a week soon. So, I decided to adjust my schedule. Furthermore, I enjoyed the higher productivity due to the morning workout.
Discussion
The following week, I found out few things to minimize the loss. For example, a light intensity cardio before the strength exercise can help with the workout. BODYPUMP also has a warmup. After a short, low-intensity cardio session, my body is more prepared to do more strenuous strength training.

For one week, I did GRIT, BODYPUMP, BODYCOMBAT, BODYATTACK, and BODYSTEP all six mornings to satisfy my curiosity. After some investigation, I modified it a little bit. I kept a short GRIT (HIIT) exercise either on my lunch (when I was working remotely) or in the early evening (if I go into the office as I plan). The addition of HIIT exercises changed made a significant difference to my body weight. I started to lose weight again without losing my muscle mass.
I added a 5–10-minute low-intensity cardio before BODYPUMP so that my strength training has the intended effectiveness. This change is helping my strength workout.
Despite the lower-calorie output, I still prefer some cardio in the morning because of the productivity gain. So, I added another Cardio session on one of the weekends to accommodate the loss of 100 calories.

What’s next
Initially, I thought of doing GRIT even on a Cardio day instead; however, I decided to add another cardio day on the weekend. I am finding out too much GRIT can cause mitochondria dysfunctions due to the stress caused by its strenuousness. You can reduce the damage by taking mitochondrial regulators and protector nutrients such as 5 grams of Leucine, 5 grams of creatine monohydrate, and 2.5 grams of betaine (Blechman, April 12, 2021). He is citing a lot of journals, so that I will check them out. For now, I am going to keep my new modified exercise program without taking these mitochondrial regulators and protector nutrients.

To improve my physical and mental condition, I decided to work on changing my lifestyle. I started with dancing Zumba on my switch, and I gradually made changes. My goal is to lose weight without losing my muscle mass. I implemented formal strength training offered by Les Mills into my exercise program last month. I have been exercising mindful eating for two months without any strict calorie or food restriction. With approximately 400- 460 minutes of activities per week, I gained 0.4 lb. of muscles till lost only 0.2 lb. Mindful eating is necessary; however, I still need to change how I eat to lose weight.

My workout schedule for the last 4 Weeks
I rotated BODYATTACK, BODYCOMBAT, or BODYSTEP for my carid days, approximately 300-330 calories per 30 minutes per session. Additionally, I walked on Saturday and Sunday, which add up to about 2 hours of activities minutes. Therefore, my average activity minutes were 400- 460 minutes per week. I achieved over 8,000 steps goals for all days except for June 29th, when I felt ill. Therefore, I had more than sufficient activity minutes for losing weight. My muscle mass had increased by 0.4 lb.
The Possible for Not Losing Weight
Why am I not losing weight? I was frustrated; however, I thought that the best way to find out the causes is to review my notes. Since I am not losing weight as fast as I would like, I must make some changes. From my notes, I came up with the following reasons why I am not losing weight.
Not Enough Cardio Exercise
I may need to increase Cardio Exercise as I do only twice per week of moderately-intensity cardio exercises. According to the U.S. Department of Health and Human Services, we must target 150 minutes to 300 minutes of moderate-intensity physical activities per week (p. 21). I did only two sessions of cardio per week which might not be adequate for losing fat. I have many activities minutes; however, approximately 250 minutes of those activities are generated from walking or doing house chores.
Not Enough Calorie Deficit
I suspected that this is the leading cause of my struggles since I exercised mindful eating. I decided how much I should be eating by listening to the needs of my body. I ate more than 1,600 calories on some days because I was starving after a long walk or workout. To lose weight, we must create a calorie deficit. To lose one pound, I need to make a deficit of 3,500 calories. I was not losing weight because I was not producing enough calorie deficit. Therefore, I need to create a calorie deficit by either doing more exercise or eating less.
Eating Not Enough or Too Much Protein at Once
Since I was still gaining muscles, I assumed that I ate enough calories and protein. So, there is a cap on how much our body can synthesize protein at once! According to the Journal of the International Society of Sports Nutrition (as cited in Venuto, 2013), you will need to eat 0.4 to 0.5 grams of high-quality protein per kilogram of lean body mass weight. For example, someone with 70kg of Lean body mass weight should eat somewhere between 28 and 35 grams of high-quality protein both pre-and post-exercise. Although, our protein synthesis cap out to about 25 to 30 grams for women (p. 179). Any excess protein above protein synthesis turns into fat. I ate approximately 70 % of my daily protein at supper. According to Layman (as cited in Venuto, 2013), the average American consumes over 65% of daily protein at dinner (p. 179). I ate enough protein because I considered total protein intake per day. However, I did not consider the timing of protein intake. So, some of my protein converted into fat since I was overeating at once. I should break up my protein intake multiple times per day.
Not Sleeping EnoughFor Two Weeks
In the 2nd week of the last challenge, I messed up my sleeping schedule for three weeks. I had days I could not sleep at all. I tended to eat more even with my mindful eating practice when I did not sleep 6 hours. Insufficient sleep prevents you not only healthy but also me you unproductive. Furthermore, poor sleep leads to weight gain and obesity (Markawld et al., 2013). I also see the tendency to eat more dense calories foods when I do not have enough sleep. Sometimes, I was scared to get on the weight machine in the morning. The number is a good way to monitor, but it can be cruel. When I gained weight for 1.2 lb, I had to think about how much cumulative weight I lost. I managed to fix my sleeping schedule last week, and now I am sleeping on the correct sleeping schedule. I wrote a blog, “Am I sleeping Enough?,” about how I tackled this program. Please check it out!
Things Need to be Changed
After making the list of possible causes for my struggle, I made few hypotheses on possible strategies to overcome struggle. My main reason for not losing weight was that I overate. Therefore, to lose weight, I must create a calories deficit by eating fewer calories or exercising more. According to Harvard Health Publishing (July 11, 2020), you should make 500 to 1,000 calories less than the total weight-maintenance calories to lose 1 to 2 pounds per week. Although, it is not recommended to eat less than 1,200 calories per day for a female and 1,500 calories per day for a male (para. 3). You can calculate your maintenance calories by the following formula.
If you do little or no exercise: Calories = BMR x 1.2
If you do light exercise (1-3 days per week) = BMR x 1.375
If you do moderate exercise (3-5 days per week) = BMR x 1.55
You can calculate your BMR by the following formula.
BMR (Base Metabolism Rate) = BMR = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years) Women: BMR = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years)
I want 500 calories deficit per week. Since my Maintenance Calorie is 1,337.3 kcal/ I want 500 calories deficit per week. Since my Maintenance Calorie is 1,337.3 kcal/ day, I could reduce only 100 calories just from eating without going below 1,200 calories. Thus, I must create a deficit of 400 calories from exercising or being active. I added 20-minute High-Intensity Interval Training on Tuesday, Thursday, and Saturday to increase energy output. Les Mills has a GRIT program. I am considering doing 20-minute short GRIT for now.

Conclusion
I did not lose as much weight as I would like at the last challenge. The main reason was I did not make enough calorie deficit. It was a disappointing result, but weight loss is a long journey. I am not going to give up on my journey. For the next challenge, I will create a calorie deficit of 500 calories per day by eating 100 calories less from my body maintenance calories and creating 400 calorie deficits from exercising. I would increase my cardio exercise to lose more fat.

To improve my physical and mental condition, I decided to work on changing my lifestyle. I started with dancing Zumba on my switch, and I gradually made changes. Since the last challenge, I began working on mindful eating. I wanted to be more contemplative with who I am, and I wanted to trust my eating. I also decided to work on increasing my muscle mass while reducing my body fat. So, I started to look for exercise programs from home that include muscle training and cardio exercise. After some research, I decided to try LES MILLS on Demand.
I must understand how much exercise I should be doing. When I tried the first 45 minutes BODYATTACK, I barely made it to the 30-minute mark. At this point, I was not sure about my physical capability. This round, I wanted to try few different types of LES MILLS exercise classes. Then, I would customize workout programs in the future.
Procedures:
(1) Experiment with a 45-minute class and stop when I could not do any exercise. After the first week, I changed to a 30-minute class.
(2) Try a class per day until I needed a rest day.
(3) Change the time of exercise to find the best time for exercising.
I used this trial period to evaluate my physical strength, flexibility, and endurance. My main goal is to figure out my workout program. I started with BODYATTACK, BODYCOMBAT, and BODYFLOW since I did not have any equipment yet.
I monitored my total body weight and muscle mass to see the progress.
I will briefly introduce BODYATTACK, BODYCOMBAT, and BODYFLOW.
BODYATTACK reminds me of a Bootcamp class I used to take. It consists of athletic movements such as running, squats, lunges, agility, push-up, core exercise, and plyometrics. It is a high-energy exercise. My Fitbit calculated I spent about 305-310 calories for 30 minutes of this exercise. The class is intense, but you can always pick a more accessible option. For example, I can choose to do squads instead of burpees.
BODYCOMBAT is like kickboxing. It used to be called BODYATTCK. When I did my first instructor certification course with LES MILLS 15 years ago, I lost 8 pounds just practicing videos every day. Muay Thai exercises were always the hardest one for me, so I was happy to do some Muay Thai exercises. Their high knee exercises give me good muscle pain. My Fitbit calculated I spent about 325-330 calories for a 30 minute-class.
BODYFLOW contains Yoga, Tai Chi, Pilates, and meditation. I usually do their 20-25 minutes body flow class before work. I am not very flexible, so I try to imitate the instructors’ poses as much as I can. BODYFLOW is not a high-energy class; however, my body feels good from stretching.
I told my husband about getting Les Mills on-demand subscription. He knew that I had instructor certifications from LES MILLS 15 years ago. So, we agreed that we would purchase equipment for BODYPUMP and BODYSTEP. Since we received the equipment kit in the 4th week, I only tried BODYPUMP twice last week.
Finding
To find out how many days I can exercise per week, I did a workout every day. As a result, I started to have pain in the arch of the foot. So, I had to take two days of rest and light exercise the following days. After three days of rest and a light workout, the pain was gone. So, I need to be more mindful of how much I exercise. I found out I could do six days of workout; however, one day must be BODYFLOW. I added a 17 minutes BODYFLOW class in the morning in addition to a 30-minute exercise, which seems to work for me. I felt much better when I stretch in the morning.
A 30-minute of exercise per day is adequate for me for now. If I do more than a 30-minute of training, I get tired. I struggled with how to fit the exercise routine into my schedule. The first week, I was so tired from the exercise that I slept in on both weekends. Then, I was not as productive on weekends either. Furthermore, I forgot to practice the piano for two days.
Benefits
It is convenient since I can exercise in my house. It is not my first time trying LES MILLS’s program. I used to go to their BODYATTACK, RPM, and BODYSTEP classes at a gym a long time ago. I loved their program, but the program was available only at GoodLife Fitness, where I lived. Since I was always traveling, it was challenging to attend some classes, such as BODYPUMP classes. I loved their BODYATTACK and RPA programs so much that I earned instruction certificates. I did not have time to teach the classes, but I could get instructor videos for the programs. When I realized that I can now do this program on demand, I was excited. It came with a 30-day trial period, but I have already known that I would enjoy their program. Now I can do their exercise program any time I want to.
Accessing a variety of exercises prevents us from becoming obese. Among nearly 1.7 million US adults, people regardless of their sexes who engaged both 150 minutes or more per week of aerobic physical activity and twice or more per week of muscle-strengthening exercise with different classes had the lowest incidence of obesity (Bennie et al., 2020, p. 332). When people engage in various activities, they tend to accumulate more minutes of total exercise time. It is recommended that you will need between 150 and 250 minutes per week of exercise to prevent weight gain, and you will need between 225 and 420 minutes per week of exercise to lose weight. Bennie et al. explain that Americans who exercise with two or more activities tend to do more than 150 minutes of exercise (p. 341). I had more than 400 minutes of training from all four weeks.
The class choreography is easy to understand. Instructors perform all routines as mirror images to the students so that attendants can follow the instruction easier. For example, an instructor performs left side steps and tells students to do a right sidestep.
Every class seems to contain squats. In addition to regular exercise, squats promote our body to lose body fat and gain lean body mass. For example, after observing 94 athletic adolescent boys, they found the group who did 100 reps per day of squats 45 sessions over eight weeks increased lean body mass by 2.7%and decreased body fat by 4.2% (Takai et al., 2013, p. 61).
Impact of my Total & Muscle Weight
I started caring more about my muscle weight than my total weight. I continue with my mindful eating. I gained 0.6 lb. of the total weight and 0.2 lb. of muscle mass during the first week because I ate more. I think I was hungrier because my body was going through sudden trauma from all the training. During the second week, I was more careful with my eating. I lost 1.4 lbs. I also lost 0.2lbs of muscle. During the third week, I made sure I ate enough protein and carbohydrates, and I lost 0.2lbs of the total weight while gaining 0.2 lbs. of muscle mass. In the 4th week, I regained 0.2 lbs., but I also gained 0.2 lbs. of muscle mass. I lost 1.0 lb. of total weight, but I gained 0.4 lbs. of muscles.
Losing fat without losing protein is more challenging than I initially thought. I may need to investigate how to eat appropriately to retrain my muscles.
The Next Action
From my 1-month experience, my approximate time of exercise was 5-6 x of 30- minutes of class. I must rest my body at least once a week. I will start with six days of exercise, but I may reduce it to 5 days.
Since I want to gain more muscle, I am considering more BODYPUMP classes per week. I will rotate BODYATTACK, BODYCOMBAT, BODYSTEP, and ZUMBA on cardio days. In addition, I may continue 20 minutes of BODYFLOW before work because little stretches in the morning made me feel good.
I am considering implementing the following schedule for the next challenge.

To improve my physical and mental condition, I decided to work on changing my habits for good. Initially, I started with only 45 minutes of Zumba 5 days per week with no food or calorie restrictions. For monitoring purposes, I did weigh almost every day, first thing in the morning. Then, I gradually added minor changes to my daily life. I started a sleep goal of 8 hours per night after the 1st week. My goal is to be in bed by 9:30 pm, hoping to be asleep by 10:00 pm every day. At approximately the same time, I introduced a 2-minute meditation before going to bed. I lost 3.7 lb. from this 4-week schedule.
Unfortunately, two days before ending this round, I had to start taking antibiotics for a day of surgery. I was still exercising a day before surgery, but I decided to push out the starting day for the 2nd round of the 4-week challenge for five days. Thanks to my lifestyle change, antibiotics and day surgery did not cause me to gain weight five months ago.
The Effects of Antibiotics
I had to take antibiotics for ten days for this surgery. I noticed that I had significant decreases in the amount of weight lost per day. For example, I lost only 0.1lb for the first 5days of the 1st week despite the exercise increase. It was not surprising since antibiotics can kill good microbes along with unwanted microbes. According to Cox et al. (2014), taking antibiotics can alter the metabolism of the host. A study found that that metabolic alteration occurred in mice taking a low-doses of penicillin. Mice taking a low dose of penicillin from youth had sustained effects on the body compositions. Low-dose penicillin strengthens the negative impact of high-fat diet-induced obesity because it disrupted the microbiota of mice (p. 705). I have been eating more fermented foods and taking some probiotics. I am not sure how long it will take me to regain all the microbes I lost.
While I was in better shape than the last operation several months ago, I also experienced difficulties falling asleep.
Loss of sleep due to antibiotics
I had a sleep problem despite the antibiotics not listing Insomnia as a side effect. The sleeping problem, which started a few days after taking antibiotics, lasted about two weeks. I began to see issues arising from not sleeping well. For example, I was not performing well in the Zumba game. I felt tired when I woke up with inadequate energy. I struggled in completing my daily to-do list. I craved pasta and rice.
Eating Out
We took out food from a restaurant nearby our house because we just completed a project in the front yard. Alas, I gained just over 2.5lb from the Gyro platter. It may be a little too salty, but I had to drink much more water to get rid of the extra salt I introduced to my body. Although the biggest problem was not because I ate the Gyro platter, I kept eating even though I was already feeling full in the middle of it. There is nothing wrong with eating out or eating the delicious gyro platter. Instead, I need to think about why I kept eating it.
It took me approximately nine days to get rid of most of the weight. I noticed all this effect because I measured my weight every day. I realized how essential to weigh myself so that I can see the pattern of my weight movement. I am not that proud of this incident; however, I learned something from this incident. I need to listen to my body.
My struggle in losing weight continues until the mid-week of the second week. I was kind of desperate since I gained weight from the Gyro platter I ate. I start losing weight again. It sucked to lose my good gut microbes to die out from antibiotics, but so did the harmful microbes, too. I need to regain good microbes and nurture them by eating prebiotics such as pistachios and cabbages. When I talk like this, my husband makes a joke that I am talking about my gut microbes as if I have pets.
For the 2nd round, I planned to add more aerobics time, and I take a course, “Designing Your Personal Weight Loss Plan,” from Coursera during this round. Since I took the first few weeks of the course, I knew this course was worth taking. I started taking this course in 2020, but I stopped after a few weeks due to priority changes. This time, I somehow felt I needed to prioritize taking this course because I felt the need for some guidance from a professional. Some content of this course is outdated. For example, the recommended tools for food journaling or planning meals are no longer usable. However, there were several tips, articles, and good books suggested in the classes. You can take it free from Coursera, and I recommend it.
There is a lot more content in this course, but I have summarized some things that inspired me:
Exercising: You will need to exercise at least 150 active minutes per week to lose weight. You can double count high-intensity exercise minutes. Some watches such as Fitbit can count active minutes.
Planning for Eating Out: When you plan to eat out or party, you can reduce calories 100-150 calories per day three days before eating out or adding 10-15 minutes of additional exercise. You can also take a smaller portion at the party so that you do not overeat.
Monitoring: Monitoring weight, calorie intake, and calorie output are essential because we can see the pattern in our weight movement. We must continue monitoring these data. According to Thomas et al. (2014), those who maintained the behavioral changes could sustain their weight loss, while many others gain back weight after the weight loss program (pp. 17-18).
Mindful Eating: Instead of depriving you of eating something you like, eat mindfully. According to Dahl (May 16, 2014), you will crave more by trying to suppress eating. The research shows that parents who enforce stringent eating rules tend to become overweight because they eat more when they can (para. 10). Instead, eat anything you want to eat, but eat mindfully.
With a bit of professional guidance, I made some changes in my strategies for losing weight. I added all conditions from the first challenges. Still, I implemented other habits: a calorie intake restriction of 1,500 calories per day, food journaling, and ring-fit adventure (switch game) as a tool for muscle exercise. I added a 60-minute Zumba workout for the 2nd and 3rd week.
Summary of My Tactics
45 Minutes of Zumba 5 times a day
Weighing every day
Aiming for an 8-hour sleep
Drinking at least 80 oz of water per day
2 minutes of meditation per day
Added:
Food restriction 1,500 calories per day
One additional session of 45 minutes of Zumba per week
One 60-minute of Zumba on 2nd and 3rd weekends started ring fit adventure one mission per day for three days per week.
Food Journaling
I should be mindful of increasing the amount of exercise. Since I was doing Zumba every day, I started to develop leg pain. I took a day off from the Zumba session. Instead, my husband and I went for a nice long walk at a nearby park. The air was fresh, and I smelled the scent of nature. Listening to birds singing or trees swaying in the wind made me feel comfortable and relaxed. I slept so well that night.
I started losing weight again at the beginning of the 2nd week. It took me over a week to lose the 2.5 lbs. I just gained from the Gyro Platter, but by the end of the 4th week, I lost an additional 2.5 lb. I lost 2.3 lb. of fat, and I gained 0.2 lb. of muscle mass. Although I lost 5 lbs. in total, 2.5 lb. out of 5 lb. was the weight I regained. The result is not as exciting, but I lost weight. I am sure I can do better next time.
I am considering reading a book, “Mindful Eating,” which was introduced by the Coursera course I took. I am considering implementing some Yoga next challenge. I also want to explore parks around Nashville going forward. The important thing is making small changes that I can sustain. That is what the Japanese believe as a Kaizen.

I decided to work on reducing my weight because I am quite a bit overweight. I noticed some negative consequents of being overweight. I tend to be hungrier than when I was average weight. My heart rate was higher. My energy level decreased. My clothing does not fit me well, and I lost confidence. I decided to challenge myself to lose weight. This blog is a summary of the progress of my first four weeks of this challenge. I experienced some benefits and some setbacks I wanted to share with you to help you lose weight.

Exercise
With a commitment to being healthy, I started with regular exercise. One of the biggest obstacles for me is making time for regular exercise. Since I am working from home, I could do 30 minutes of exercise during my lunchtime and 15 minutes after work. I picked my favorite workout, Zumba fitness, for my starting exercise. I used to go to Zumba class back in Canada, and I have only good memories associated with the activity. Zumba can be a strenuous exercise, and the calories consumptions can rise to approximately 230kcal with my weight within 30minutes. I use Zumba Burn it Up!. I played the Zumba game since we acquired a console that was able to run it last Christmas, and I like the game a lot. Having a good feeling about the activities is an excellent way to keep me going with my commitment.
Equipment
The equipment I use for my exercise commitment is Fitbit Charge 3/4, Nintendo Switch, and Zumba Barn it up!
Fitbit Charge 3 & Charge 4: I have two Fitbit watches listed here because I had to replace my Charge 4. I loved Charge 4 as it tracks your activity duration and calculates your active minutes by considering the workout intensity. The workout intensity level is an essential factor for the amount of calorie output as it changes the amount of exercise expenditure per minute. For example, you will be spending much more energy by hiking a hilly mountain than walking on a flat road. The reason is your heart rate is higher for more vigorous exercise. Fitbit is not a cheap watch, but it eliminates my time to calculate activity minutes. You can use a heart rate monitor for around $20-$30 instead. The minutes for a high-intensity activity are double activity minutes.
Nintendo Switch and Zumba Burn it up!: I used a Nintendo Switch Game for an exercise program. You can use any exercise program as it is more accessible, and you feel you can commit to doing so. My husband, who disliked jogging, used Zombies, Run!, a phone app to make his jogging more interesting. He likes Zombie stories. He can now run 10 km in one go despite his physical challenges due to his brain trauma five years ago.
There are some improvements in my vital measurements, such as my resting heart rate and sleep quality in the first week. For example, my resting heart rate improved from 68 to 65, and my sleep quality increased from 76% to 83%. I was anxious about recent increases in my resting heart rates; it was an unexpected change.
It was not only good news, though. Soon, I started realizing exercising is not enough to lose weight. After a week of exercise, I lost only 0.3lb with 420 minutes of weekly active minutes. I began to review my Fitbit records, so I had to make modifications to my programs.
I noticed the following problems: sleep duration, water intake, and food intake. They are all equally essential factors in being healthy, but I must make choices. I was in the middle of a financial audit, and I did not have time to research all the factors. It is crucial to understand why I am modifying my programs. I was unsure about implementing the changes in my food intake as not all diets available are healthy nor practical. I decided to work on sleep duration and water intake. Since Fitbit cares about and tracks them, they must be important factors.
Sleep Duration
Sleep duration is essential for losing weight. According to Markawld et al. (2013), insufficient sleep leads to weight gain and obesity due to the change in energy expenditure and the changes in satiety and hunger hormones. Inadequate sleep will increase our energy expenditure per minute to compensate for the lack of energy; however, the hormone changes also signal our brain to eat more carbohydrates and fat, resulting in increased weight gain. Duration of sleep impacts females (pp. 5695-5696).
Sleep duration is a crucial factor for losing weight. To improve my sleep duration, I decided to review my habits. One of my biggest obstacles was I have no sleep schedule. I also like watching YouTube or reading on my smartphone, resulting in less than 6 hours of sleep. Even with my blue light filtering glasses, how good is not having enough sleeping time. So I will make modifications to these habits. First, I made a strict sleeping schedule that imposed a penalty to pay my husband. Second, I made it more difficult to access my mobile devices as my mobile devices are one of the factors taking away my sleep time. Third, I made a habit of meditating two minutes before going to bed. At first, it was challenging, but I managed to increase my average weekly sleeping duration to 7hours and 43 minutes by the end of the 3rd week.
Water Intake
Hydrating our body is essential for our health. There is an exciting news journal you can read on the John Hopkin University website. There are multiple benefits to drinking enough water, but I focused on a few relevant factors to this program.
According to HR NewsWire published (Jan 15, 2020), water helps hydrate our body and lose weight. Research conducted by Elizabeth Huggins suggested drinking 2 cups of water before eating breakfast, lunch, and dinner decrease food intake by 22% on average. A 2013 study reported that drinking approximately two cups of 71F water before breakfast, lunch, and dinner helped reduce body mass index and improve body composition score by 14% among healthy adults due to the increases in the body’s metabolic rate 33% average. The reason is the body tries to recover the heat lost from drinking cold water.
Finally, drinking water helps us exercise more effectively. Melina Jampolis, a board-certified physician nutrition specialist, explains that water dissolves and distributes electrolytes required for muscle contractions. Therefore, proper hydration will more effectively gain muscles. We tend to lose hydration during exercise. Sweat has its essential role in regulating our body temperature. So, it is crucial to have enough water before and during training (para. 4 – para. 15).
I struggled with implementing this habit. Initially, I set up a drinking schedule like 12 oz after waking up, 12 oz at 10 a.m., and so on. It became more challenging when I could not take time to drink due to auditors’ phone calls that lasted more than I would like. Then I missed the scheduled time to drink the 12 oz of water at 10 a.m. After few days of struggling, I drank 12oz of water after I go to the washroom. Somehow this method worked for me—the act of going to the restroom triggers my memory to drink 12 oz of water. Well, everyone has to go to the washroom sometimes after all.
I think having a sufficient sleep gave me more energy for being active. The effect of improving my sleeping habits and drinking enough water brought me a fantastic result of losing 3.7 lb in 2 weeks.
Conclusion
My tip is to work on your goals even when you encounter some challenges. Losing weight can be tricky. In some weeks, you may gain weight, or it may not change at all. It can be frustrating. A slight modification in programs may help you to accomplish losing weight. The most important thing is that you will keep working on it because maintaining a healthy weight will become your lifetime commitment.
