Maximum protein intake in one sitting?

Does anyone know what the maximum amount of protein I should take in in one sitting? I thought I've heard that there's an amount of protein that you can take in a short period and beyond that the protein just gets converted to glucose? I'm a very active person, doing CrossFit 5 days/week and Army PT/Running 5 days/week. I eat a lot, but was wondering if I should optimize my nutrition and supplementation by restricting my protein intake in one sitting to a certain amount and just spread it out more throughout the day.

In addition to that, what kind of period between meals/protein servings? I usually go 4 hours or less between meals/snacks of some kind. I'm on strict Paleo with plenty of animal fat.

Re: Maximum protein intake in one sitting?

Don't take this as gospel because I am certainly no expert but I have read/heard around the campfire that you can digest about 30g of protein per sitting and up to 50g shortly after an exercise session.

I, too, have wondered how long it takes to digest that protein so that you can take in more but haven't been able to find conclusive answers. I'll keep checking the thread to find out information from someone who knows a bit more. =]

Re: Maximum protein intake in one sitting?

The way I understand it (the posted article kinda confirms me) your body will use all of the protein calories you give it. They don't magically dissapear. However, if you really overshoot your caloric needs the protein will undergo lipogenisis/glucogenisis (did I just make up a word?) and will be stored.

Re: Maximum protein intake in one sitting?

Gluconeogenisis isn't really an issue when you talk about protein intake. (on constrained portion diets like zone). About 10-15 % of energy come from protein on average. There also maybe additional needs (dependent on exercise regimes) to prevent catabolism.

The study shows a lack of significant increase of protein synthesis after 30g, but it would be interesting to see a larger study that just 8 participants before the described trend is cemented into literature.
