My gf brought over a 12pack of diet pepsi the other day and I noticed that I've been drinking a soda rather than pigging out. I'm ~12-13% bf and was going to start cutting soon, in hopes of upper single digits. (this might help me resist urges ) I haven't been drinking soda of any kind for about a year now (diet or regular)... Mainly just because I prefer orange juice... I remember some post a while back saying that the carbonation in sodas can create ether links and essentially turn muscle into fat. The other day I thought "Why not soda... I drink a fair amount of beer, and thats carbonated too" But I just did some reading and saw that most beers get carbonated as a result of fermentation, not CO2 injection... So, as some clarification, is the carbonation in soda really bad for you? What about beer/champagne?
