How Much Protein Can My Body Absorb in One Meal

The answer depends on your history. Your body adapts to your intake this is what we studied & documented. The World Health Organization has a project studying protein intake for more than a century of clinical trials their mission is to find solutions to stamp out third-world famine & understanding protein turnover is important for health & many other reasons.
 
Your body takes several days to adapt to an intake. The idea there is a limit per meal is not true. If you are used to consuming 20 grams & suddenly consume 200 grams then there is a chance that you are overconsuming. However, if you steadily consume 200 at a sitting your body can adjust & adapt & begin to use it.
 
Protein intakes are overstated & overrated in an attempt to sell protein drinks powders, supplements, etc. They are used by people who bodybuild. Most people assume they train like a bodybuilder because they pick up a heavy weight & it’s simply not true. Unless you are competing on stage. Or training with a trainer who can have the same intake as a natural bodybuilding athlete would require.
 
If you consume large amounts of protein your body becomes less efficient at processing it & uses much of it for energy. If you consume a small amount of protein your body becomes extremely efficient at using that protein & burns less for energy so it’s a trade-off.
 
Studies show that either keeping calories the same & increasing the percentage of calories from protein or increasing calories overall even if the increase comes for carbs, can contribute to gaining muscle mass &improving protein turnover.
