Protein absorption

[GiantSlayer3]

I was always told your body can't digest more than 40g of protein in 2-3 hours .
On Twitter sama hoole a personal trainer said you can eat 2 meals and get 200g of protein and be fine all day ?

What's the word ?
Is it better to eat several meals through the day and split up protein intake or two meals and done ?

Your body can digest more than 40 grams of protein at one time.

The reason behind having steady protein throughout the day is because your body can't store amino acids. Not that it can only break down a set number at a time.

So if I ate 2 pounds of beef at one time .
The protein wouldn't be as beneficial since I'm not getting the amino acids stored. That's what youre saying ?

It's more beneficial to have a steady flow of amino acids. Not just 1 or 2 big peaks.

Your body can digest up to 100g and probably more over the course of time. Great study was done in 2024 just on this topic. Layne Norton did a nice review of the study if you don't want to read the whole thing.

You’ve gotta think too, that different proteins digest at different speeds. I would imagine slamming like 100g of whey isolate probably doesn’t all get absorbed. But 100g of casein probably does. It probably heavily depends on what you’re eating not how much you’re eating. Thats my guess

This is true. Especially Whole Foods that will take a long time to be broken down and digested completely will provide a steadier stream for an extended period.

From the randomized human trials of protein digestion, what is added along with the protein is what greatly effects the time more than the type of protein itself. Example: Consuming whey with fats would cause digestion to occur more slowly, but still completely digest without it. There have been 3 solid studies thus far on this, so we simply need more evidence. If I had to guess the amount of protein consumed and digested would be similar to training volume. Gains will be a linear asymptote, with a point of limited returns.

Along the same lines; another reason I give VERY little thought to the glycemic index generally. The whole meal composition matters a ton. Unless you’re just downing a bowl of plain rice and that’s it I guess

As for protein (especially meats or something casein based) if you’re eating 4-6 meals and even maybe periworkout shakes too, you really should have a steady amino stream. Meal size matters too. A 12oz steak will be digesting and providing amino acids a lot longer than say 6oz of cod or tilapia. But then again, we must take the whole meal into account too.

Actually, from the literature there is no difference in protein digestion/bioavailability whether you consume 3 meals or 6. The steady amino stream and anabolic window has pretty much been disproved at this point. It's total daily protein that is what truly matters.

This is coming from someone who used to eat 6-8 meals eating every 2 hours thinking it was life and death.

there was a recent study that showed basically no limit. They only tested up to 100g protein but they did not find a limit to how much.
its easily searchable.

I wouldn’t think there would be a difference in digestion or bioavailability based on meal frequency. If I understand correctly, if it’s all equated the larger meals will in a sense “compensate” by taking longer to digest vs say 6 smaller meals with it equaling out in the end, yes? So either way it remains sustained?

I was moreso just driving home that ESPECIALLY with us and how frequently most of us consume protein, it’s certainly not a concern

I just changed up my macros as a personal experiment - PRO is now at about 355g/day. Now every YouTuber out there is starting a low protein diet to see if their gains will stay or not. So I'm pounding ground beef like it's going outta style - watching these natural kids try to get by on 60g/day while I eat 90g/meal LOL. It's like someone just decided to go out and take the advice of a 155lb female dietician who swears people only need 60g....maybe 80g of protein tops for hypertrophy. Then these dieticians tell you that anything more is just extra calories and can make you fat!

For me it is! lol

Thread '8 Protein Myths That Are Holding Back Your Gains'

Sep 1, 2025

Too much protein can damage your kidneys. Consume protein immediately after your workout; if not, it will not be effective. These are some of the protein myths that are spreading in the world of bodybuilding.

Unfortunately, we tend to believe them without questioning the science behind these claims. As a result, we fall into the trap of confusion, poor dietary choices, and even health risks that hinder rather than help our progress.

The truth is, your body doesn’t operate on bro-science. It...

Thread 'The Protein Trick for Men Over 40'

Jan 27, 2025

Age-Related Protein Utilization
As you age, your body doesn't absorb or utilize protein as efficiently as it used to. Here's what to do about that.
Bodybuilders and people who lift weights are usually ahead of the training and nutrition game. Bro-science aside, we often figure things out before the researchers conduct the studies to confirm our in-the-trenches instincts.

Here's something life-long lifters, men over 50, have told me: "Chris, I don't know why, but I have to eat even more protein than I did in my 20s if I want to keep my muscle mass!"

Are they onto something? Do our...

Thread 'What Happens When You Eat 100 Grams of Protein At Once?'

Dec 8, 2024

The Trommelen Study​

Is 30 grams of protein the maximum you can use in one meal? New research says no. Here's why.​

A new revelation about protein just dropped in the journal Cell (1). Let’s dig into it.

People always say, “The body can only use 30 grams of protein at once!” Is that true? Well, imagine eating a 16-ounce steak. If you can only use 30 grams of protein at once, you’ll find steak-shaped deposits in your toilet the next morning. That doesn’t happen. So, where does the steak go?

More protein helps build bigger muscles (2, 3, 4), but is there a limit to how much...

Actually the science destroys that myth and always did. Every meta-analysis ever done on protein consumption shows huge amounts are completely safe to kidneys.
