Is too much protein dangerous?Jan 10, 2023
Is too much protein dangerous?
Twenty-five years ago, there was plenty of skepticism about protein.
After all, bodybuilders ate lots of it—and they experimented with all kinds of “questionable” things.
Plus, the late 1990s ushered in the rise of high-protein diets for weight loss—an approach many health experts then labeled as “unsafe.”
Over the years, much of the hand-wringing about protein has faded. (And some of those same experts now advise people to “eat more protein.”)
But one claim just won’t seem to die: “Protein is bad for your kidneys.”
Spoiler: It’s a myth.
Here’s why: The concern about high protein and kidneys began because doctors tell people with poorly functioning kidneys—usually from pre-existing kidney disease—to eat a low-protein diet.
But, but, but…
There’s a big difference between avoiding protein because your kidneys are already damaged versus protein actively damaging healthy kidneys.
It’s the difference between jogging with a broken leg and jogging with a perfectly healthy leg.
Jogging with a broken leg is a bad idea.
Doctors would probably tell you not to do that. But does jogging cause legs to break? No.
Same with protein and kidneys.
Eating more protein does increase how much your kidneys have to work, just like jogging increases how much your legs have to work.
But protein hasn’t been shown to cause kidney damage—again, just like jogging isn’t going to suddenly snap your leg like a breadstick.
In fact, clinical studies show people can eat up to 4.4 g of protein per kg body weight (or 2 g per pound) without any short term health problems. (Granted, that’s a very high intake and very few people would ever voluntarily consume that much.)
How Much Protein Do You REALLY Need?
For the average person eating a standard diet, protein deficiency isn’t a concern.
However, “not deficient” doesn’t mean optimal.
It just means getting enough protein to maintain function and prevent malnutrition.
👉🏾For sedentary, generally healthy adults, about about 0.4 g per pound is enough to cover basic daily requirements. (That’s about 60 grams for a 150-pound person.)
But because protein is involved in so many essential processes, protein needs can go up you’re:
🏋🏻♀️Training hard frequently or have a heavy physical job
🤒Injured, sick, or recovering from surgery
👴🏻Older (because protein digestion tends to reduce with age, so you need more to meet requirements)
💪🏽Trying to lose body fat but still maintain muscle (or you’re trying to maximize muscle)
If you fall into these groups, research shows you want to shoot for around 0.7-1.0 g per pound. (That’s about 105-150 g for a 150-pound person.)
But if all that sounds too complicated…
Don’t worry about the numbers.
Instead, just shoot for 1-2 palm-sized portions of protein at each meal.
Of course, if you’re not even close to that now, you’ll probably find it difficult to get there overnight.
So start from wherever you are, and try to eat just a little bit more.
For example, if you only have 1 palm-sized position of protein a day, try to have 2.
Or if, like many people, you typically get most of your protein at dinner, can you focus on adding a palm to your breakfast and/or lunch?
Try it for 2 weeks, and if it’s working for you—that is, you enjoy it, you’re moving you closer to your goals, and it’s not disrupting your life—build on your success.
That’s how you make lasting progress.
Check out my favorite protein powder - It is by Transparent Labs
What I like about this protein powder...
It helps me achieve my muscle building goals!
So here are some things I have learned about protein powder:
"Whey" protein powder gives you about 99% of the amount stated in a bio-available way for your body to use it.
Compared to soy protein powder at about 80% and pea protein powder at about 50%.
No way! Whey!
"Grass fed" means the source is getting the best food source for their production of the protein.
"Isolate" means it is easier on my digestive system.
"28 g Protein" per serving is outstanding! This helps boost my first meal of the day protein amount to help stimulate muscle synthesis (more on that in my newsletter/blog - so be sure to subscribe)!
"Mocha Latte" actually just tastes really good! Got any cold leftover coffee from the morning? Use that instead of water to make your shake!
I have it as a shake at the end of my lunch: usually a salad with 3-5 oz of chicken or salmon.
Transparent Labs produces a great product I have confidence in. Use the link in the bio of this post to get $20 off your order. Full disclosure: With the code, if you use it, you get $20 off and I get $20 off my next order - win win!
