This source says no; Protein will not be converted to fat. The conversion of Protein to Fat would be a long process for the body to do, and most likely would only happen in the instance that your body is WAYYYY over-supplied with all other nutrients that it could possibly strip out of the protein molecule.
But there are also a zillion which say Yes - it is converted into fat! This is why I hate science. Can't Jesus just tell me the correct answer?!
Complete an utter nonsense that does not even stand the "common sense" test. If simply eat protein was the answer to obesity, nobody would be fat.
However, the ratio of protein to fat conversion is the low. 95% of excess fat is stored as fat, reflecting how easy fat is stored. 85% excess of carbohydrate is stored as fat. I forget the percentage for protein, it is like 80%. I need to run but I will get the correct number.
BTW, the methodology is to establish an diet that is in energy balance then feed an excess and note the effects.
It boggles my mind on how wrong these muscle heads are regarding protein. I suspect that their websites sell protein supplements has a lot to do with it...
Well, Pure protein is the first stage of the Dukan Diet, which has documented positive effects as well. When I had crazy food-reactions a few years ago I was put on it for 2 weeks, and was literally eating nothing but PURE protein, cottage cheese, greek yogurt, chicken breast, turkey etc. etc. in as much quanitity as I wanted - i.e. eat as much as I liked - and I ended up LOSING weight, while still maintining strength.
I guess the thing is all bodies handle different nutrients differently. Our chemical composition is different, and chemicals are what digest the nutrients...
Like I said, why can't Jesus just give me teh ansir!
