Does excess protein get converted into fat, assuming there is full glycogen storage in the muscles? I've read that excess amount of AA will be converted into citrate, shuttled out of the mitrochondrial matrix, and converted into acetyl-CoA, where de novo lipogenesis will occur.
Sounds like babby wants to show everyone how smart he is
Not all of it gets converted into fat. AA can feed into a lot of other biosynth pathways including metabolites in the TCA cycle, signalling molecules, etc
And acetyl-coa, fatty acids contrib to more than just fat - lipid membranes, steroid biosynth
About half of all ingested dietary protein is metabolized in the liver. Some of it is oxidized for energy or converted into other things (including glucose and ketones) for use elsewhere. Protein oxidation rates change in response to intake. So, when protein intake goes up, oxidation will increase. If protein was going to be converted to fat, it would first have to be converted to glucose and only if the amount produced were then in excess of daily maintenance requirements would there be conversion to fat. That isn't going to happen under any reasonably normal circumstances.
Right, right, typo. Meant 1.3-1.7 g/kg.
That said, it seems most researchers and bodybuilders are divisive when it comes to the recommended protein intake. Everytime I try to Google this shit, it basically boils down to:
>oh hey guys amerifats are totally eating too much protein, do 1.5 g/kg
>nah brah 1 g/lb is totally proven and effective
>contradictory research blah blah blah
