Twenty-five years ago, protein was surrounded by skepticism and misconceptions. It was a nutrient often associated with bodybuilders and high-protein diets that were considered “unsafe” by some health experts. Fast forward to today, and the perception of protein has undergone a significant transformation. Many health experts now advise people to “eat more protein,” recognizing its importance for overall health and well-being. However, one persistent myth still lingers: “Protein is bad for your kidneys.” In this comprehensive guide, we’ll debunk this myth and explore the intricate relationship between protein consumption and kidney health.
Understanding the Kidney Myth
The concern about high protein intake and kidney health primarily stems from doctors advising individuals with poorly functioning kidneys, usually due to pre-existing kidney disease, to follow a low-protein diet. This recommendation has contributed to the misconception that protein is detrimental to kidney health. However, there’s a crucial distinction to make: Avoiding protein due to existing kidney damage is not the same as claiming that protein actively damages healthy kidneys. It’s akin to advising against jogging with a broken leg—it’s not that jogging causes broken legs, but rather, it’s ill-advised when there’s an existing issue.
Debunking the Protein-Kidney Myth
Let’s clarify this myth further. Yes, consuming more protein does increase the workload on your kidneys, just as jogging increases the demand on your leg muscles. However, the crucial point to emphasize is that protein has not been proven to cause kidney damage in individuals with healthy kidneys. In clinical studies, individuals were able to consume up to 4.4 grams of protein per kilogram of body weight (or 2 grams per pound) without experiencing any short-term health problems. While this level of protein intake is exceptionally high and far exceeds what most people would voluntarily consume, it illustrates the safety of protein consumption for healthy kidneys.
Determining Your Protein Needs
Now that we’ve debunked the myth, let’s delve into understanding how much protein you actually need. For the average person following a standard diet, protein deficiency is not typically a concern. However, meeting basic protein requirements doesn’t necessarily equate to optimal health. It merely ensures that you’re obtaining enough protein to maintain bodily functions and prevent malnutrition.
For sedentary, generally healthy adults: Approximately 0.4 grams of protein per pound of body weight is sufficient to meet basic daily requirements. For instance, a 150-pound individual would need around 60 grams of protein.
However, protein requirements can vary based on several factors, including your level of physical activity, health condition, age, and fitness goals. You may need more protein if you fall into one or more of the following categories:
Engaged in frequent strenuous exercise or have a physically demanding job: Individuals who engage in regular intense training, physical labor, or sports may require higher protein intake to support muscle recovery and growth.
Recovering from illness, injury, or surgery: During recovery, your body’s protein needs increase as it repairs tissues and supports immune function.
Advanced age: Older individuals may require more protein due to age-related reductions in protein digestion and absorption, making it necessary to increase intake to meet requirements.
Weight management goals: If you’re trying to lose body fat while preserving muscle mass or aiming to maximize muscle growth, higher protein intake can be beneficial.
For those who fall into the categories mentioned above, research suggests a protein intake ranging from 0.7 to 1.0 grams per pound of body weight (approximately 105 to 150 grams for a 150-pound person) may be more suitable.
Simplifying Your Protein Intake
For many people, calculating precise protein needs can be overwhelming. Fortunately, there’s a simpler approach: focusing on portion sizes. Rather than obsessing over specific gram counts, you can aim to include 1 to 2 palm-sized portions of protein in each meal. This method provides a practical way to ensure you’re getting an adequate amount of protein without the need for complex calculations.
If you’re currently far from reaching this goal, don’t despair. Progress can be gradual. For example, if you typically consume only one palm-sized portion of protein a day, aim to increase it to two. Alternatively, if you tend to consume most of your protein at dinner, consider incorporating a palm-sized portion into your breakfast or lunch.
Remember, the key to making lasting progress is starting from where you are and gradually building on your success. It’s a journey towards optimizing your protein intake to meet your specific needs and goals.
In conclusion, the myth that too much protein is dangerous for your kidneys is just that—a myth. Protein is a vital nutrient that plays numerous essential roles in your body, and consuming it in moderate to high amounts is generally safe for individuals with healthy kidneys. Understanding your specific protein needs, whether based on physical activity, health condition, or fitness goals, can help you make informed dietary choices. Rather than getting bogged down by complex calculations, focus on portion sizes to simplify your protein intake. By doing so, you’ll be well on your way to optimizing your protein consumption and supporting your overall health and well-being.

I offer online nutrition coaching to clients who are ready to quit dieting and start looking and feeling better, with more confidence and increased energy levels – without complicated diets or painful workouts
What exactly is “nutrition coaching”… and how will it help you reach your goals?
When it comes to losing weight and getting the body you want, “eating better” is one of the most important steps. The only problem?
Most of the common diet advice you receive simply isn’t sustainable…
- “Avoid your favorite foods… forever!”
- “Don’t eat after 7pm!”
- “Weigh and measure every morsel of food you eat!”
If you’ve tried something like this before and “failed”—or just couldn’t stick with it—you’re not alone.
(And it’s definitely NOT your fault.)
I talk to people every day who are trying to muster up all the willpower they can find to diet their way to a better body… but they still aren’t getting the results they want.
The good news? There’s a better way.
My nutrition coaching focuses on strategic, doable daily actions that are designed to fit into YOUR lifestyle. With this approach, you’ll learn how to:
- Eat better—without dieting or feeling deprived.
- Lose weight—without giving up your favorite foods.
- Ditch the food rules—overcoming the guilt and shame.
- Feel energized all day—so you can enjoy all the things you want and need to do.
- Get the results you’ve always wanted—and build the healthy habits you need to stay that way for good.
Bottom line: My goal is to help you learn how to “eat better” so that it becomes easy, consistent, and automatic.
No restrictive dieting. No weighing or measuring your food. No “one size fits all” meal plan.
Instead, you’ll learn how to bring healthy eating into your lifestyle and get in amazing shape—while building the habits you need to stay that way for good.
How is nutrition coaching different from fitness coaching or personal training?
As a coach, my number one goal is to help my clients reach THEIR goals. Doing that effectively requires me to constantly look for opportunities to learn new skills and hone my craft.
This is exactly why I chose to become a Certified Nutrition Coach through Precision Nutrition.
I’ve now been trained by the best of the best, so I know what works.
(The nutrition method they teach is backed by science and has been proven to work with over 100,000 of their own clients… so it’s the real deal.)
The best part? The knowledge and skills I’ve gained can help you finally get the results you want—and keep them for life.
Through the rigorous training I’ve received, I learned that while exercise is a crucial part of losing weight, feeling good, and achieving optimal health… it’s only half the equation.
The other half—as you may have guessed—is nutrition.
I’d actually argue that nutrition is more important than exercise, because while you spend a few hours working out each week, challenges around eating and food can happen anytime (some would say all the time!).
That’s why having a coach there to guide and support you is crucial.
Don’t get me wrong: Exercise is very important. But no amount of exercise will ever be able to “outwork” bad nutrition habits. So in order to help you get the life-transforming results you deserve—I’m excited to be able to offer nutrition coaching in an official capacity.
What I learned while becoming a Certified Nutrition Coach opened my eyes to a whole new way of doing things. And through this science-proven approach, I’m ready to help you get even better results through healthy nutrition habits.
