In the long run, does it offer any kind of additional benefit in terms of muscle growth or faster recovery or better metabolism? Have you guys noticed any difference in taking a protein shake before going to bed?
Thanks!
Timing is FAR more important than total daily intake. When Canadian studies compared those who consumed all of their daily protein for breakfast and those who spread it out throughout the day, the latter deposited measurably more muscle FROM THE SAME TOTAL GRAMS.
That is because animals have NO place to store amino acids except as temporary lean tissue and that process is rate-limited. If one dumps in more protein than can be utilized, the excess is wasted by conversion into glucose. THAT is why the "bros" at the gym claim that they NEED hundreds of grams of protein. The most that one is really going to accumulate per week is 1 kg/2 pounds of lean tissue and that utilizes ONLY 24 grams per day or 1 gram per hour.
EVERY gram that does not become tissue is BURNED, usually by being first converted into glucose.
Growth continues for perhaps 3 days. EVERY hour in which more than one gram is supplied produces NO additional growth. Every hour in which one gram is NOT supplied is a permanent loss.
The same Canadian research found that most dinner intake did not last to the next morning and NEITHER did fast-digesting whey shakes, even 40-60 grams at a serving. Casein consumed at bed time DID deliver the 1-2 grams throughout the night and required only 10-20 gram intake. In the best case, one might require even less.
It also found that full-fat cottage cheese digested more slowly than casein powder and proved far more cost-effective.
Too much protein or carbohydrate DOES raise insulin and reduce GH release BUT muscle growth depends on the isoform of IGF=1 generated within the muscle and it is independent of GH.
Muscle growth is powered by a LOT of glucose, not a lot of protein.
