presents episode 404 | Dr Ted Naiman
Revero podcast with Dr Shawn Baker

Is there an upper limit to amount of protein eaten in a day?
-theoretical upper limit in terms of getting rid of nitrogen
-must excrete nitrogen
-deaminate amino acids (removed from excess proteins)
-you could easily double, triple the 1g per body weight target
-if quadruple, may get into trouble
Studies: cyclists
-heavy cycling workouts
-drinking whey protein at 80% of calories
-over 600g protein per day
-they had no problems eliminating ammonia
-no problems with toxicity

Dr Shawn Baker: If I eat two steaks a day, is half of that protein lost?
Dr Ted Naiman: that is completely not true
-when you eat a large bolus of protein, you get a slowing effect
in the small intestine, an ileal break, that:
-slows down the transit time so much that
you eventually absorb all of the protein eaten
-there are many people eating one meal a day
with no problems
-it is on a U shaped curve...
-so, once a day, once a week...at some point
it gets beyond optimal
-my opinion: 2 meals a day

As you get thinner and thinner, must eat protein more frequently...
-eating some of it for energy;
-otherwise, you will catabolize lean mass
-that is why bodybuilders, after show prep is done
-eat protein every few hours to prevent catabolism, because
-their fat stores are too low to harvest
calories from them

We have protein overfeeding studies...
-dump 1000 calories of protein on top of existing diet
-don't gain any fat mass at all
-lean mass & energy expenditure goes up slightly
-thermic effect is so high that 30% of calories are just gone
"We should really call protein
3 calories per gram, or even
slightly lower!"
