Maintaining Weight with Kidney Disease: The Unexpected Challenge of Summer Exercise

Brian’s fitness journal after a brain stroke

When you have kidney disease, you will face the unexpected challenge of summer exercise. This evening, you’ll find me doing something many people would probably envy.

I’m deliberately snacking.

A bowl of dry cereal now sits beside me, and I keep reaching into it every few minutes in an ongoing effort to replace the calories that disappeared during today’s exercise. It may not be the most glamorous recovery meal, but it is crunchy, convenient, and currently working overtime.

Every summer, I face the same struggle: the challenge of summer exercise.

Keeping my weight up.

Our backyard isn’t especially large, but it is built on a steep hill. Mowing it is far more demanding than people usually imagine. It feels less like ordinary yard work and more like a long endurance workout that just happens to leave the grass looking nicer afterward.

The physical activity itself isn’t the real problem.

Replacing the calories is.

Because of my kidney disease, I have to be careful about almost everything I eat. Protein, sodium, potassium, and phosphate all require close attention. Those restrictions eliminate more than just large steaks and salty snacks. Even foods that most people think of as healthy, certain colorful vegetables, dairy products, and many fruits, have to be eaten thoughtfully and in moderation.

Rather than relying on one “perfect” food, my wife and I constantly rotate what I eat so that no single nutrient becomes excessive.

Managing my diet has become something of a long-term strategy game.

Protein and sodium are the nutrients I monitor most carefully. I also take medication for high blood pressure, another condition closely tied to my kidney health. Every meal becomes a balancing act between providing enough energy and avoiding foods that could make my lab results less than ideal.

Last summer, I thought I had found the perfect solution.

Melon.

It seemed refreshing, easy to eat, and ideal for helping maintain my weight.

Unfortunately, blood tests revealed that it contained far more potassium than I could safely consume on a regular basis. So my brilliant nutritional discovery quietly retired after one season.

Sometimes your laboratory results become your least forgiving food critic.

Of course, exercising is not optional.

Running, strength training, and even mowing the lawn are all important parts of maintaining my health. If I burn more calories, however, I also have to replace them.

Hence the cereal.

Tomorrow offers another opportunity to replenish those calories. After our grocery trip, I’ll finally get to enjoy a slice of cake and finish the leftover pizza from last weekend.

Before anyone concludes that I have discovered the world’s greatest fitness program, there is one small detail.

Tomorrow is also my regular 10-kilometer run.

So those extra calories already have a job waiting for them.

Such is life.

Most people spend the summer trying to lose weight.

I spend mine trying to convince the scale to stay exactly where it is.

When Staying Healthy Means Trying Not to Lose Weight

Brian’s fitness journal after a brain stroke

Most people spend the summer trying to lose a few pounds. I spend it trying not to. lose weight. I have a kidney disease, and maintaining weight in kidney disease is hard.

Every year, as the weather warms up, I find myself facing the same challenge: keeping my weight where it belongs. It sounds almost unfair to complain about losing weight, but everybody has their own peculiar set of problems, and this one happens to be mine.

Part of the reason is simple.

I have maintained relatively high muscle mass for my age by exercising consistently for many years. After my stroke, I became even more committed to staying active. At first glance, that sounds like a wonderful success story.

The catch is that muscle is expensive.

Not financially, thankfully, but metabolically. Muscle requires energy every hour of every day, whether I’m running, mowing the lawn, or quietly reading a book. It is like employing a team of energetic workers who insist on being paid three meals a day.

Summer only makes the challenge greater.

Our backyard includes a steep lawn that requires several hours of mowing. Altogether, it usually takes about five hours of work, although I wisely divide it over two days. Add regular strength training and my running schedule, and my body becomes a remarkably efficient calorie-burning machine.

Unfortunately, increasing my food intake is not as straightforward as it sounds.

Because of my kidney condition, I cannot simply eat whatever I want. My diet requires careful moderation. I have to limit protein, avoid eating excessive amounts of potassium-rich foods, and keep phosphate intake under control as well, rather than eliminating everything; we aim to maintain a balanced diet so that no single nutrient becomes excessive.

Even with careful planning, maintaining my weight remains surprisingly difficult.

This morning offered another small reminder of how unpredictable life can be.

I woke up earlier than usual, only to discover it was raining. Rather than racing the weather, I decided the bed was temporarily winning the negotiation and stayed there until my alarm sounded.

By then, almost miraculously, the rain had stopped.

I hurried outside for my run, hoping to finish before the next shower arrived. Fortunately, I accomplished both goals. I hit my target pace and avoided the rain.

Technically.

The humidity, however, had other ideas.

By the time I returned home, I was completely soaked anyway. Apparently, Nashville’s weather makes umbrellas seem merely decorative.

After peeling off my thoroughly saturated running clothes, I stepped onto the scale.

To my relief, I had gained just over two pounds.

I am still below my preferred weight range, but at least I am moving in the right direction. Considering how much energy disappears into running, yard work, and everyday exercise, I have learned to celebrate small victories wherever I can find them.

Sometimes that victory is a faster run.

Sometimes it finishes before the rain arrives.

And sometimes, rather surprisingly, it is simply watching the number on the scale move upward.

The Mysterious Case of My Monday Weight That Didn’t Move

Brian’s fitness journal after a brain stroke

After my run today, I stepped on the scale expecting the usual Monday plot twist—only to find that my weight and body composition hadn’t changed since Saturday. This was deeply suspicious.

For the past several weeks, Monday has reliably been my heaviest day of the week. I’ve learned not to take it personally. I usually blame the weekend—and more specifically, pizza. Delicious, sourdough-based, entirely worth it pizza.

My kidneys, however, do not behave like those of a perfectly cooperative adult. Depending on what I eat, my body becomes very enthusiastic about holding onto water. Most days, we eat healthy, homemade meals. Pizza is strictly a once-a-week luxury. Still, every Sunday I make sure pizza happens. Every Monday, my weight usually responds accordingly—thanks to a combination of glycogen storage and water retention.

So today’s unchanged number was unexpected.

I generally try not to obsess over my weight. It can swing by a few pounds easily, and I’ve learned not to panic. This past weekend, I ate exactly as I usually do. My exercise routine was also mostly unchanged—except for a peaceful three-kilometer walk with my wife on Sunday. The weather was lovely, and she wanted some sunshine. I wouldn’t expect that walk to single-handedly rewrite my Monday numbers, but I can’t think of any other explanation either.

I track my weight alongside my other biometrics because my nephrologist uses these trends to monitor my overall health. When we meet, he checks for sudden changes in weight, blood pressure, or heart rate. His rule of thumb is simple: sharp shifts usually mean something is going on inside the body.

Since I’m less active now than I was in the summer, I actually expected maintaining my weight to become easier. But because I move less in winter, I’ve also cut back on snacks. With kidney disease, almost everything seems to contain something I’m supposed to limit—phosphate, sugar, potassium, salt. Sometimes avoiding food altogether feels like the safest strategy.

Because my weight usually fluctuates more than this, today’s stability caught me off guard. At the same time, it means I need to be more careful this week. Starting lower than usual raises the risk of losing muscle too quickly—and that’s something my doctor very much does not want.

So for now, I’ll watch the numbers, eat carefully, move thoughtfully, and let the scale do its strange little science experiment in peace.

From Ice Cream Regrets to Yogurt Wins: My Summer Health Hack

Written August 5, 2025

Hello, Dear Readers,

This summer, the scale and I have been in a tug-of-war. Mowing the lawn knocks two or three pounds off me overnight, so keeping my weight steady is like trying to hold sand in a colander. For a while, I tried to outsmart nature with ice cream—but my doctor quickly pointed out I was basically spoon-feeding myself sugar bombs.

Between high activity levels and dietary restrictions, holding on to calories is like trying to keep water in a sieve. So when I saw the scale tip just slightly above my target range, I actually felt a tiny flicker of triumph. Of course, I know the number will likely melt away tomorrow—mowing tends to rob me of 2–3 pounds overnight.

In my quest to keep the needle from sinking too low, I once leaned on ice cream. It seemed like the perfect solution: tasty, calorie-dense, morale-boosting. My doctor, however, disagreed. Apparently, three scoops of Rocky Road a day is less “nutritional genius” and more “sugar landmine.”

That’s when my wife’s yogurt came to the rescue. Every few weeks, she whips up a fresh batch—unsweetened, creamy, and miraculously not sour. Honestly, it tastes better than most store-bought kinds. She even turns it into smoothies with frozen fruit, sometimes drizzling in honey, but usually letting the fruit do the heavy lifting. It’s healthy, satisfying, and—bonus—doctor-approved.

I’ve now paired this yogurt with cantaloupe whenever my weight starts slipping. The change has worked wonders. Back in early July, I was dealing with puffy feet and a mild gout flare-up. Since switching to this new regimen, the swelling has eased, and the gout has vanished. My wife keeps asking to inspect my feet now, worried about my kidneys (which once landed me in dialysis). I hadn’t realized how much I’d kept those little flare-ups to myself until she started hovering with genuine concern.

Looking back, I’m reminded that even small changes can cause ripples—sometimes helpful, sometimes disastrous. Ice cream seemed clever until it wasn’t. Yogurt and cantaloupe, though, are proving to be a simple, sustainable win. And with my doctor allowing me an extra 20 grams of protein per day—bringing me up to a grand total of 36 grams—I feel like I’ve unlocked a dietary superpower. (If you’ve never measured out 36 grams of protein, let’s just say it makes even a small chicken breast look like a feast fit for a giant.)

The solution turned out to be much simpler (and doctor-approved): my wife’s homemade yogurt paired with juicy cantaloupe. No sugar, just fruit, protein, and pure refreshment. The results? Puffy feet and gout flare-ups—gone. Kidneys—behaving. Weight—finally staying in the healthy range.

I’ve learned that small choices matter. Ice cream caused more trouble than it solved, while yogurt and cantaloupe quietly did the heavy lifting. And with my wife still cranking out yogurt every weekend, I’ve found a strategy that’s not only sustainable but—dare I say it—delicious.

Life with Kidney Restrictions and Weight Challenges

Written June 13, 2025

Hello, Dear Readers,

Well, I survived another workout today—barely. And to add a plot twist, the scale tells me I’ve lost three pounds since yesterday. I didn’t misplace them on purpose, I swear.

Now before you start sending congratulatory fruit baskets (please don’t, I can’t eat most of them), let me explain. My kidneys have been staging a quiet rebellion for some time now, and part of their protest involves limiting my diet. Combine that with a surprisingly high level of activity, and voilà—I’m losing weight faster than a sock in a dryer.

Summertime brings its own delightful chaos. I have to become a hydration ninja, dodging lab abnormalities like I’m in some kind of medical obstacle course. One wrong move—too little water—and my lab results go haywire. Last year, my cholesterol levels pulled a disappearing act. I wasn’t even mad. Just impressed.

To keep some order in our culinary kingdom, my wife and I plan our weekly menu. Not because we’re gourmet masterminds, but because food waste makes us both twitchy. That, and we’ve basically built our diet around chicken breasts. Mostly chicken breasts unless we go for occasional salmon or plant-based protein. Why? Well, pork doesn’t agree with my wife—upsets her stomach. Same goes for shrimp and crab, so those little delicacies are benched.

Now me? I’m working with a whopping 36 grams of meat protein a day. Thirty-six. That’s like…a sad scoop of shredded chicken. On days with family dinners or special events, I may tiptoe over the limit, but I know my wife will quietly adjust the weekly menu like a stealthy nutritional accountant.

Grains? Limited. Protein? Monitored like a suspicious package. Bananas? Handle with caution. Basically, if it tastes good or feels indulgent, I probably have to negotiate with my kidneys first.

That’s why I bake mini pastry puffs every weekend—a humble little treat to keep my weight from disappearing entirely. I don’t devour them. I ration like I’m on a space station. Ice cream? That’s my red alert dessert. I only pull it out when I notice I’ve lost too much weight. Like today. (Silver linings, people.)

After my stroke, things shifted. But rewind to when I first moved to Nashville—oh, I was running not as much, but enough to build muscles in my calves. I built so much muscle that my mom was surprised. True story. 

Back then, my wife did everything—a full-time job and most of the house chores. It took me some time, but I eventually wrestled the outdoor responsibilities away from her. When you’re exercising and doing yard work in Tennessee heat, weight loss isn’t a question—it’s a guarantee. For me, the diet restrictions added another layer. It’s not that I’m sick and therefore underweight. It’s more like… I got strong, and my kidneys decided, “Cool, but no extra calories for you.”

Just yesterday, I finally hit my target weight again. And now? Boom—dropped below it. It’s irritating, sure, but not the end of the world. I’ve got my strategy: tiny pastries, sneaky scoops of ice cream, and a carefully curated menu. Let’s be honest—if the solution to a problem is “eat more dessert,” I’m not going to complain too loudly.

Until next time,
Stay hydrated, stay balanced, and treat your kidneys like the finicky coworkers they are.

—Yours in protein math and pastry puffs.

Title: Refueling After Yard Work: Balancing Hunger and Health

Written 5/17/2024

Hello Dear Readers,

Yesterday, I managed to complete mowing the remainder of the yard. This endeavor took a considerable amount of time and energy. Afterward, I found myself overwhelmingly hungry. This intense hunger isn’t unusual after three hours of strenuous physical activity. Yet, the quantity of food required to satiate this hunger surprised me. My post-activity meal consisted of a generous bowl of spaghetti, four granola bars, and a cookie. Only then did I feel the edge of my hunger dull—not full, just no longer hungry. I learned this important distinction from my grandparents, who emphasized it as a practical approach to maintaining a healthy weight.

Given the intensity of my hunger yesterday, I half-expected the scales this morning to suggest that my weight had dropped alarmingly low. I intend to maintain my current weight, so I need to be more mindful. The thought made me frown a bit. To my mild surprise, the scale showed that I was only half a pound lighter than the previous day, which was already slightly below the lower end of my desired weight range. I felt better. I can manage that by eating marginally more.

I make it a practice to regularly monitor my weight to ensure I maintain a healthy balance. On days like yesterday, when my physical activity leads to a higher calorie output than intake, it’s natural to see a slight decline in weight. Additionally, we are vigilant about our salt intake due to my high blood pressure issues. Even though salty foods tend to increase water retention, impacting weight measurements, I allow for what I consider an acceptable daily fluctuation—about 10% over or under my target weight.

As I prepare for my morning run, I’m curious how my robust eating from yesterday will influence today’s weight measurement. It’s a delicate balance, managing food intake against physical activity and overall health, and it’s a journey that always keeps me engaged and attentive to my body’s needs.

Navigating through these challenges, I continue to learn more about my body’s responses and how best to maintain a stable and healthy weight while still enjoying the foods I love and the activities that keep me fit. This balancing act is not just about numbers on a scale; it’s about feeling good, staying healthy, and living life to the fullest.
