Protein: The Body’s Repair Crew

Day 9 of 100 Days Muscle Resistance Workout Challenge

Topic: How protein supports repair and growth; daily needs vs. reality.

Learning Material

When you exercise, you’re not just burning energy—you’re creating tiny tears in your muscle fibers. Protein is what repairs those tears, making muscles stronger and more resilient each time. Without enough protein, recovery slows, progress stalls, and you may even lose muscle despite working out.

Key Insight

Protein as the Builder: Think of protein as the repair crew for your muscles. Every rep you do is like creating “construction sites.” Without enough workers (protein), the job gets delayed or left unfinished. Research shows that regular, sufficient protein intake is essential to maximize muscle repair and growth.

Daily Needs vs. Reality:  Most people underestimate how much protein they need. General health guidelines suggest ~0.8 g per kg of body weight, but for active individuals, 1.2–2.0 g per kg is often recommended. That means someone weighing 150 pounds (~68 kg) may need closer to 80–130 grams per day for optimal recovery. In reality, many people fall short, often getting the bulk of their protein at dinner instead of spreading it evenly across the day.

Distribution Matters: A controlled feeding study of healthy adults found that evenly distributing protein intake across meals produced significantly greater 24-hour muscle protein synthesis than consuming most protein in a single meal, despite identical total protein intake1. Aim for 20–30 grams per meal to keep your “repair crew” working around the clock. A breakfast of just toast and coffee, for example, misses an important opportunity to fuel recovery and growth.

Example / Story


Imagine two people with the same workout routine. One eats most of their protein at dinner, while the other spreads it across breakfast, lunch, and dinner. After several weeks, the second person recovers faster, feels less sore, and builds more lean muscle—all because they gave their muscles steady building blocks throughout the day.

My Reflection 

Since increasing my protein intake to a sufficient level, I’ve noticed my muscles repair more quickly. I try to spread protein throughout the day, and I already feel better than before—less fatigue and steadier energy. This makes it clear that I wasn’t eating enough protein previously.

I’m aiming for about 1.25 g of protein per kilogram of my target weight (50 kg), which comes out to ~62.5 g daily. Here’s what that looked like today:

  • Two eggs in the morning — ~12 g
  • About ⅓ cup of yogurt — 7–10 g
  • ½ serving of protein shake — 14 g
  • ¼ cup of tofu — 5–7 g
  • Chicken (3 oz) with sweet potato and carrots — 20–25 g

Altogether, I actually went a little over my calculated target, which is fine since my goal is to lose 15 pounds without losing any muscle mass.

I’ve also decided to adjust my food prep habits. I used to make yogurt every two weeks, but now I’ll prepare it weekly to keep up with demand. The price is still higher than before, though it has dropped recently. Since I’m not much of a meat eater, I’ll rely more on eggs and yogurt to help cover my protein needs.

Biometric data

Change in Weight from Day 1: -2.8 lb.

Skeletal Muscle: 39.2%

Muscle Mass: 94.6 lb.

Adjustment Ideas (Strategic adjustment)

  • Add at least 20 grams of protein to breakfast (e.g., eggs, Greek yogurt, tofu, or a protein shake).
  • Track protein intake for one day to see how close you are to your daily target.
  • Replace one carb-heavy snack with a protein-rich one (nuts, cheese, edamame, or cottage cheese).

Fuel for Growth: Why Nutrition Matters for Muscles

Day 8 of 100 Days Muscle Resistance Workout Challenge

Topic: Why nutrition matters for muscle growth and recovery (macronutrients overview).

Learning Material 


You can train as hard as you want, but if your nutrition isn’t supporting your body, muscle growth and recovery will stall. Muscles are living tissue, and they rely on nutrients to repair, rebuild, and adapt after exercise. Understanding macronutrients—protein, carbohydrates, and fats—gives you the building blocks to make your training truly effective.

Key Insight

Protein – The Building Blocks: Protein provides amino acids, which your body uses to repair damaged muscle fibers after workouts. Think of protein as the bricks in a construction project. Without enough bricks, you can’t build a strong structure. A controlled feeding study found that evenly distributing protein intake across meals resulted in significantly greater 24-hour muscle protein synthesis than consuming most protein in a single meal, despite equal total protein intake1.

Carbohydrates – The Energy Supply: Carbs often get a bad reputation, but for active people, they’re crucial. They replenish glycogen (stored energy) in muscles, fueling both workouts and recovery. Without enough carbs, you may feel sluggish, and your muscles won’t perform at their best. Imagine trying to drive a car without enough gas—protein might build the car, but carbs keep it running.

Fats – The Silent Supporters: Healthy fats don’t directly build muscle, but they play a supporting role by regulating hormones like testosterone and growth hormone, which are essential for muscle development. They also provide long-lasting energy. Think of fats as the quiet backstage crew that keeps the show running smoothly.

Example / Story


Consider two runners training for the same 10K. One fuels with balanced meals—protein at each meal, carbs before and after workouts, and healthy fats daily. The other under-eats protein and avoids carbs, thinking it will help them lose fat. The first recovers faster, feels stronger, and gradually builds lean muscle. The second struggles with fatigue, sore muscles, and slower progress. The difference isn’t training effort—it’s nutrition.

My Reflection 

I’ve started focusing on eating more protein. Because my husband has dietary restrictions, I often eat much less protein than I need, even while exercising. Like him, I noticed that my muscles were slower to recover, and instead of getting leaner, my body just stayed the same. Cutting calories too low also seemed to reduce my muscle mass, which made me realize that increasing protein is essential.

I once tried the Keto diet, but I don’t think that approach fits me—especially since I do cardio every day and need carbohydrates for energy.

Today’s protein intake looked like this:

  • Two eggs in the morning
  • About ⅓ cup of yogurt (with some protein)
  • One protein shake
  • ¼ cup of tofu (with additional protein)

Later tonight, I’ll also have some chicken, which means I’m spreading protein throughout the day. Eating multiple times at work can be tricky, but at the very least, starting my morning with protein makes a huge difference. It helps me recover better and keeps me full, which makes it easier to stay consistent.

Adjustment Ideas (Strategic adjustment)

  • Add a protein source to each meal (aim for 20–30 grams).
  • Choose complex carbs (brown rice, oats, sweet potatoes) instead of refined ones at least once per day.
  • Swap one processed fat (butter, fried food) for a healthy fat (olive oil, avocado, nuts).

Biometric data

Change in Weight from Day 1: -2.6 lb.

Skeletal Muscle: 39.3%

Muscle Mass: 94.6 lb.

Kitten Recovery and Her Onesie, Determined Little Patient

Brian’s fitness journal after a brain stroke

Kitten Recovery and Her Onesie

This morning began with a small but impressive discovery:
Our cat had partially escaped her onesie.

When I walked into the room, I found her with both front legs free, looking rather proud of herself. Fortunately, the incision remained covered, and after a quick inspection, everything looked intact. No licking, no damage—just a bold attempt at freedom.

Our cat is nothing if not determined. Once she decides something must happen, she commits fully. The onesie, apparently, has become her current adversary.

After reviewing the situation, I suspect the issue came down to user error—specifically, ours. The collar may not have been tightened enough. The onesie includes an adjustable cord, so we secured it more firmly this time. With luck, this will prevent future escape attempts… though I would not underestimate her creativity.

She only has one more day of mandatory pain medication. The vet mentioned we can request more if needed, and we will keep that option open. The challenge, of course, is that cats are experts at hiding pain. They prefer subtlety, which makes observation a bit like detective work.

At the moment, she looks mildly miserable in her onesie.

On the bright side, her appetite remains strong—perhaps too strong. Since we are limiting her movement during recovery, she is gaining a bit of weight. A well-fed but slightly annoyed patient is still a good sign overall.

We even took a few photos and shared them with friends and family. Objectively, she looks very cute in the onesie.

Subjectively, she strongly disagrees.

Now we are counting down the days. In about ten days, she should be free from her temporary outfit. While the onesie is practical and undeniably adorable, I am quite certain she will celebrate its removal with great enthusiasm.Until then, we remain on escape-watch, adjusting straps, monitoring recovery, and negotiating daily with a very determined little patient.

Muscles and Mindset: The First Week in Review

Day 7 of 100 Days Muscle Resistance Workout Challenge

Topic: Looking back on Week 1: what you learned about muscles and how you’ll build on it.

Learning Material


The first week of your 100-day journey is complete—a small milestone, but an important one. This is the time to pause, reflect, and connect the dots between what you’ve learned and what you’ve experienced.

Key Insight

Knowledge + Action = Momentum: This week showed that muscles are far more than “strength.” They protect against aging, support metabolism, regulate blood sugar, and even sharpen your brain. But learning isn’t enough—the key is taking consistent action, even in small amounts. A 10-minute daily routine, when paired with steady reflection, is already creating momentum.

Progress Is Subtle at First: The body doesn’t transform in a week, but the signs are there: a hint of soreness, a shift in eating habits, a little more energy. These small signals are like early green shoots in a garden—they prove growth is happening, even if it’s not yet visible in the mirror.

Systems Beat Willpower: Relying on motivation alone is unreliable. Creating systems—like pairing cardio with strength training, starting the day with protein, or journaling your reflections—makes progress automatic. Over time, systems carry you further than bursts of determination ever could.

Example / Story


Think of this first week as planting seeds. If you scatter a few seeds in the soil, you won’t see much change in seven days. But with water, sunlight, and patience, those seeds grow into something that lasts. Your short workouts, reflections, and small dietary tweaks are the “watering and sunlight” for your long-term health.

My Reflection 

After six straight days of workouts, I finally took my first rest day. The sudden addition of strength training left my body unable to fully recover, which surprised me. Since I’ve always been consistent with cardio, I didn’t expect such fatigue from a relatively small extra routine.

To stay on track, I’ve built my strength training into my existing cardio habits. After cardio, I measure my weight before showering—grouping these actions together as one “set” makes them easier to remember. I’ve noticed that my weight fluctuates depending on what I eat. For example, salty foods make me retain more water, even if I eat fewer calories. Because of that, I won’t overanalyze the daily numbers. Instead, I’ll treat each weigh-in as data and focus on the long-term trend, much like my husband does.

To monitor more effectively, I’ll start logging my meals. This will allow me to compare food intake with weight and recovery, though I won’t dissect the details every single day. The goal is to collect enough data to step back later and look at the bigger picture objectively.

This week, I learned three important things about my body and mind:

  1. My leg and abdominal muscles ache on the same day, showing that different areas recover at different rates.
  2. Eating protein in the morning, such as eggs, keeps me feeling less hungry throughout the day.
  3. Increasing protein intake helps me recover more quickly.

Workout Plan: I’ll keep the same routine for one more week and then adjust slightly, especially to challenge my legs more.

Nutrition Plan: Starting tomorrow, I’ll begin a food journal to track what I eat and better connect it to my progress.

Biometric data

Change in Weight from Day 1: -1.4 lb.

Skeletal Muscle: 38.9%

Muscle Mass: 94.6 lb.

Adjustment Ideas (Strategic adjustment)

  • Choose one exercise you enjoyed most this week and commit to improving it slightly (add a rep, hold longer, or do one more set).
  • Refine your morning routine by pairing protein (like eggs, yogurt, or tofu) with cardio or strength for a strong start.
  • Set a weekly “mobility check” (e.g., sit-to-stand test or timed walk) to track how your independence and strength evolve over time.

Stronger for Life’s Little Lifts

Day 6 of 100 Days Muscle Resistance Workout Challenge

 Topic: Why muscle makes daily tasks easier—from carrying groceries to climbing stairs. The importance of having functional strength for daily life.

Learning Material 

When we think about strength, we often imagine athletes lifting heavy barbells or sprinters exploding off the starting line. But the true gift of muscle is how it transforms the ordinary moments of life.

Muscle is like a quiet assistant that works in the background, making everything from hauling grocery bags to getting up from a chair smoother and safer. Without enough strength, even simple tasks can feel draining or risky.

Key Insights:

Every day efficiency

Stronger muscles make daily movements feel lighter and less draining. Something as ordinary as carrying a laundry basket or climbing stairs demands less oxygen and energy when your legs and core are well-conditioned. A recent systematic review and meta-analysis found that even low-dose resistance training produces meaningful improvements in muscle strength and functional capacity, suggesting that substantial health benefits can be achieved with relatively small training volumes1. With more intense resistance training, the benefits become even greater. While ratings of perceived exertion (RPE) are subjective—based on how hard your body feels like it’s working—they consistently align with real physiological improvements.

Joint protection

Muscles act as shock absorbers for your joints. When your quadriceps and glutes are strong, each step down the stairs places less stress on your knees. Think of muscles as the suspension system of your body—without them, your frame takes all the impact.

Independence and aging

One of the biggest predictors of independence in older adults is leg and grip strength. The ability to rise from a chair or carry groceries without strain often decides whether someone can live independently. Building strength now is like making deposits into a “mobility savings account” for later in life.

Real-world Example/Metaphor

Imagine carrying three heavy grocery bags from the car to your kitchen. If your muscles are strong, you’ll breeze through it like an escalator gliding upward—smooth, steady, no drama. If your muscles are weak, every step feels like an uphill climb, and you’re praying the bag doesn’t split open halfway. Strength turns “chores” into “just movement.”

My Reflection

After five days of muscle training, the second and third days left me with plenty of soreness. Today, however—surprisingly—I don’t feel nearly as much. There’s still a bit of calf discomfort and an unusual ache in my inner thighs, which I especially noticed when climbing stairs. It makes sense: stairs call heavily on the calves, and apparently, those smaller muscles are still catching up.

Yesterday, my fatigue peaked, and I ended up sleeping an extra hour. It reminded me how crucial proper rest days are, even when I’m alternating muscle groups.

My digital weight analysis shows I carry a good amount of muscle, thanks to years of cardio, yoga, and BodyAttack classes. But I also have a relatively high body fat percentage. If I were to lose about 15 pounds of fat—while holding onto all my muscle—I’d be in the range of an athlete’s body composition. That translates into 52,500 calories (3,500 x 15) of careful body management.

I know from past experience that losing fat without losing muscle is a balancing act. My plan is to aim for a very small daily calorie deficit while keeping protein intake high enough to support muscle growth. At a 150-calorie deficit per day, it would take roughly 350 days to reach my goal.

So—challenge accepted.

Biometric data

Change in Weight from Day 1: -1.6 lb.

Skeletal Muscle: 39.1%

Muscle Mass: 94.8 lb..

Adjustment Ideas (Strategic adjustment)

  • Micro-habit tweak: Add 1–2 sets of “functional” moves into your day—like carrying two moderately heavy bags around the room to mimic groceries, or doing step-ups on a safe surface.
  • Mindset shift: Reframe chores as “hidden workouts.” Each time you carry laundry or squat to pick something up, you’re practicing strength training in disguise.
  • Diet/recovery: Include a protein-rich snack (like Greek yogurt, boiled eggs, or tofu) within 1–2 hours after training to help your muscles repair and stay ready for daily life.

Kitten Recovery After Spay Surgery

Brian’s fitness journal after a brain stroke

This morning began with a delicate operation: administering two pills to our cat.

Surprisingly, she handled it quite well. After a small meal, she climbed onto my lap and stayed there for most of the day, as if she had officially decided I was her recovery station.

My wife returned to work today—duty called, especially during audit season—so I took full responsibility for medication duty. I had been observing her technique closely, and today I attempted it myself. Thankfully, it worked. No dramatic protests, no long negotiations—just a quick, efficient delivery.

Both pills were painkillers with sedative effects, which meant our usually energetic kitten transformed into a very quiet, very sleepy version of herself. She did not even purr while I petted her, which felt unusual enough to double-check that she was still, in fact, our cat.

She spent most of the day asleep on me.

As a result, I skipped my push-up session—clearly, I had been reassigned as “human heating pad.” However, I still managed to complete my planking and stretching, so I consider that a partial victory in discipline.

At this stage, she needs constant reassurance. We gave her another dose of medication later so she would remain calm through the night. She clearly senses that something is different. She is less alert, more subdued, and far sleepier than usual. For a naturally athletic and energetic cat, this must feel like an entirely different life.

For now, we are keeping her in my office to limit her movement. If she suddenly remembers that she enjoys running and jumping, we would prefer not to witness that experiment.

We also dressed her in a post-surgery onesie to prevent her from licking the incision. She is still adjusting to the concept of “wearing clothes,” which she does not fully appreciate. At one point, she attempted to reverse out of it—a bold but unsuccessful strategy. The onesie, however, does its job well. It allows her to sleep comfortably and eat more easily compared to the cone.

When my wife returned home, she immediately took over comforting duties. Our kitten clearly wants to stay close to someone at all times. At one point, my wife tried moving her to the bedroom, but we quickly relocated her back to the office—she was already showing signs of wanting to resume her normal, highly active lifestyle.

For now, rest remains the priority.

The good signs are there: she is eating well, sleeping deeply, and gradually settling into recovery mode.

With a bit more rest—and perhaps fewer wardrobe complaints—she should be back to her usual energetic self very soon.

Strong Muscles, Sharper Mind

Day 5 of 100 Days Muscle Resistance Workout Challenge

Topic: The connection between physical strength, neuroplasticity, and mental clarity.

Learning Material

We often think of muscle training as something that shapes the body—but it also shapes the brain. Every time you challenge your muscles, you’re also boosting brain health through a process called neuroplasticity—the brain’s ability to form new connections and adapt over time.

Exercise as Brain Fertilizer

When you contract your muscles, they release proteins called myokines. These travel through the bloodstream and act on the brain, encouraging the growth of new neurons and connections. One of the most powerful of these is BDNF (Brain-Derived Neurotrophic Factor), sometimes nicknamed “Miracle-Gro for the brain.”

Strength Training and Mental Clarity


While cardio has long been associated with brain health, strength training plays a unique role. Studies show that resistance training improves memory, attention, and decision-making. A randomized controlled trial of adults aged 70–80 found that regular resistance training significantly improved executive function and functional performance, supporting the role of strength training in maintaining cognitive health and brain plasticity in older age.1 Think of it as decluttering your mental desktop—each rep gives your brain a little more clarity and focus.

Stress Resilience and Mood


Strength work doesn’t just sharpen thinking—it helps regulate mood. Training teaches the brain how to cope with stress by lowering baseline cortisol levels and releasing endorphins. People who lift consistently often report feeling calmer and more emotionally balanced.

Example / Story


In one study, older adults who practiced strength training twice a week not only improved their mobility but also scored higher on cognitive tests. Some participants described it as “lifting weights for the body and the brain.” The same is true for younger adults—just a few weeks of resistance training can improve focus at work or school.

My Reflection

I woke up an hour later than usual today, worn out from muscle training. Still, I pushed myself to go out for my morning cardio. My muscles are sore, which reassures me that I’ve challenged them enough to start breaking down and rebuilding.

Since starting this project, my eating habits have shifted. I’m paying more attention to protein—adding extra eggs, for example. My husband struggles to get enough protein, and I used to use that as an excuse not to eat much myself. I’m a picky meat-eater, so my options are limited. Beans and tofu work for me, but I know I’m still not getting quite enough.

Lately, my first meal has been a salad with eggs and a splash of olive oil. It keeps me full and helps me avoid snacking. Even though I feel tired, the combination of training and healthier eating habits leaves me with a deeper sense of energy.

Morning cardio has been my anchor for years. With my naturally low blood pressure, it’s the only way I can shake off sluggish mornings. Once I get moving—whether brisk walking or light jogging—I feel energized and focused. Strength training, on the other hand, has never been my favorite. But I’ve noticed that since adding it, I’ve had more sustained energy and clearer focus throughout the day, even when I wake up exhausted.

It makes me wonder: how much more impact will strength training—and reflecting on it through journaling—have over time? I’ll keep writing about it, so I can see how both my body and mind continue to change.

Biometric data

Change in Weight from Day 1: -2.2 lb.

Skeletal Muscle: 39.1%

Muscle Mass: 94.8 lb.

Adjustment Ideas (Strategic adjustment)

  • Experiment with one new protein source this week (e.g., lentils, tempeh, Greek yogurt) to expand your options.
  • Prioritize 7–8 hours of sleep to give muscles and brain the recovery time they need.
  • Add a brief “cool-down reflection” after training: jot down one thought or idea that felt clearer post-exercise.

Strength is Your Body’s Secret Safety Net

Day 4 of 100 Days Muscle Resistance Workout Challenge

Topic: How strength improves balance, reduces risk of injury, and aids in recovery from illness

Learning Material 

When we think of “strength,” we often picture lifting heavy weights or building bigger muscles. But strength has another, quieter role—it acts as your body’s safety net. Strong muscles stabilize your movements, protect your joints, and give you reserves to recover when life throws challenges your way.

Balance is Built on Muscle

Your brain and inner ear help with balance, but muscles are what actually keep you upright. Strong legs and a stable core reduce wobbles, slips, and stumbles. A systematic review of 29 studies involving more than 4,300 older adults found that community-based exercise programs combining resistance training, balance work, and functional movement significantly reduced the risk of falls in adults aged 65 and older1.

Strength is Protection Against Injury

Weak muscles force your joints and tendons to take more stress, which makes them prone to injury. Stronger muscles act like shock absorbers, reducing the impact of daily life—whether that’s climbing stairs, jogging, or lifting groceries. Think of muscles as the cushioning system in your sneakers: without them, every step feels harsher and riskier.

Muscle is a Recovery Reservoir

During illness or after surgery, the body often loses muscle. The more strength you have beforehand, the faster your recovery. Muscles also store proteins and glycogen, which your body uses during times of stress. Doctors sometimes call the muscle the “reserve tank of health”—you don’t notice it until you need it most.

Real-World Example

Imagine someone awkwardly stepping off a curb. A strong person’s core and leg muscles automatically stabilize them, preventing a fall. A weaker person might stumble, twist an ankle, or worse, end up in the ER. That little bit of extra strength is the difference between a quick laugh and weeks of recovery.

My Reflection (Polished in your tone)

Changing habits can be tiring for the body. After three days of extra muscle work, my legs and abs are sore. What surprised me, though, is that my weight hasn’t budged at all these past two days. We use a digital scale (RYPHO), which doesn’t just measure weight—it also shows body fat, muscle mass, and more. That part I like.

But I also realized I’ve been carrying a strange fear of weighing myself. Through my emotional resistance journal, I uncovered that it comes from a fear of failure. Fitness isn’t about perfection or copying someone else’s blueprint. It’s about finding my rhythm, my strategies, my route to better health. Acknowledging that fear helped me release it. Instead of worrying about the number, I’m choosing to focus on the process of getting healthier.

What concerns me is that my muscle aches are lingering. The last thing I want is to push my body so hard that it never gets the chance to heal properly.

Biometric data

Change in Weight from Day 1: – 1.2 lb.

Skeletal Muscle: 39.0%

Muscle Mass: 94.8 lb.

Adjustment Ideas

  1. Active recovery: Add a light yoga or stretching day so sore muscles can recover without losing momentum.
  2. Mindset shift: Treat the scale as “data collection” rather than a verdict. Focus on long-term patterns instead of day-to-day numbers.
  3. Nutrition tweak: Add one extra serving of protein on workout days (like eggs, yogurt, or lean fish) to speed up muscle repair.

Kitten Spay Surgery Day: A Stressful Morning with a Happy Ending

Brian’s fitness journal after a brain stroke

Today, it was our kitten-spay-surgery-day, and it was a very important and slightly dramatic day for our kitty.

This morning started as usual. She woke up with me and immediately led us downstairs, full of energy and expectation, ready for breakfast. Unfortunately, she did not realize that today came with… restrictions. Because of the surgery, she had not been allowed to eat after 8 p.m. last night.

So while she confidently marched toward her food bowl, we had a different plan.

The moment she entered the room, I gently (but decisively) placed her into the carrier. She looked at me with the kind of betrayal usually reserved for tragic novels. I felt terrible—but we still had to take her to the vet.

Thankfully, my wife had the day off for Presidents’ Day, which made everything easier. She could stay home and pick our kitty up as soon as the clinic called.

After we dropped her off, the waiting began.

I felt worried, but my wife looked even more concerned. She mentioned the paperwork we had to sign before the procedure—the standard forms that politely remind you that even routine surgeries carry risks. Rationally, we knew this was normal. Emotionally, it still made the situation feel heavier.

A couple of hours later, we finally received the call:
the surgery went well.

Relief arrived instantly.

The vet told us she would be ready to go home in a few more hours. Those hours felt long, of course—but I still had things to do. Now I had a clear deadline, so I quickly prepared and went out for my run.

After finishing my run and showering, it was finally time to bring her home.

When we picked her up, she was wearing the classic “cone of shame” and still a bit groggy from the sedatives. She looked mildly offended by the entire situation and will probably hold that opinion for the next few days.

Fortunately, my wife ordered a surgical onesie, which should arrive tomorrow. Once that comes in, our kitty can retire from cone life—something she will deeply appreciate.

For now, we also have to give her medication over the next few days. Luckily, my wife has experience. She used to work at a cat shelter during university, so she has mastered the art of administering pills to cats—quickly and efficiently, ideally before the cat fully understands what just happened.

Her method is simple:
be fast, be calm, and leave the cat slightly confused rather than suspicious.

In the end, the difficult parts are temporary. The long-term benefit—no future discomfort from heat cycles—is permanent.

Our kitty may be annoyed today, slightly dramatic tomorrow, and mildly judgmental for a few days…

But soon enough, she will forget all of this and return to her usual energetic, pouncy self.

Muscles: Your Metabolic Powerhouse

Day 3 of 100 Days Muscle Resistance Workout Challenge

Topic: The role of muscle in burning calories, regulating blood sugar, and preventing metabolic disease.

Learning Material

Muscles aren’t just about movement—they’re one of the most important regulators of your metabolism. Think of them as both the engine that burns fuel and the sponge that soaks up sugar from your bloodstream. Without enough muscle, the body’s energy system runs less efficiently, increasing the risk of weight gain, diabetes, and metabolic disease.

Muscle and Calorie Burning

Muscle tissue burns calories even when you’re sitting still. The more muscle you have, the more energy your body uses to simply stay alive. While a single pound of muscle won’t dramatically boost your metabolism on its own, over time, building and maintaining lean mass helps keep your daily calorie burn steady—making it easier to manage weight.

Muscle and Blood Sugar Control


Muscles are the largest site in the body for glucose uptake. Every time you contract a muscle—whether lifting weights or going for a brisk walk—it helps shuttle sugar out of the bloodstream and into muscle cells for storage or use. A Japanese cohort study of young and middle-aged women found that lower relative skeletal muscle mass was strongly associated with reduced insulin sensitivity and impaired glucose tolerance, even among participants who were neither overweight nor diabetic1. This is why strength training and cardio are powerful tools for preventing type 2 diabetes.

Muscle and Metabolic Health

When muscle mass is low, the body becomes less sensitive to insulin, leading to higher blood sugar and increased fat storage. This can trigger a cascade of health problems, including obesity, diabetes, and heart disease. In contrast, keeping muscles active makes them act like a “shield” against these conditions.

Example / Story

Imagine two people who eat the same meal: one has strong, active muscles, while the other has very little muscle. The first person’s muscles quickly absorb the glucose, keeping blood sugar stable. The second person’s body struggles, leaving sugar in the blood, which eventually gets stored as fat. Same meal, completely different outcomes—all because of muscle.

My Reflection

At first, I thought I hadn’t pushed myself hard enough on Day 1 since I didn’t feel sore right away. But this morning, I woke up with aches in my legs and glutes—clear proof that the exercises were working after all.

When I checked my body composition, I noticed something surprising: my muscle mass is in the “dark green” range, which is high for my age. The real issue isn’t muscle but fat—most of my body fat comes from subcutaneous fat, while my visceral fat is less of a concern.

This shows me I need a balanced strategy: keep strengthening my muscles, while also adding more cardio and adjusting my diet to manage fat more effectively.

Today, I made a small but intentional change by starting breakfast with two eggs and a salad. I know this will support fat loss and help me feel satisfied. Still, I realize I’m not eating enough protein overall, so I’ll need to pay closer attention to my intake. After breakfast, I added some light leg stretches—another small step to keep my body moving and recovering.

Biometric data

Change in Weight from Day 1: 0lb

Skeletal Muscle: 38.8%

Muscle Mass: 95 lb.

Adjustment Ideas

  • Add a short cardio session (e.g., 15–20 minutes of cycling, brisk walking, or jogging) 3–4 times a week to pair with muscle training.
  • Reduce added sugars or refined carbs in one daily meal to help keep blood sugar stable.
  • Incorporate more protein + fiber into snacks to feel full longer and support muscle repair.
