Appears to happen in some people's bodies if they increase their protein, or at least some people correlate the 2 things. FWIW I don't tell anyone to do low carb, I tell them to research and find something that works for them. My friend that got up to 315 I even tried to get him not to do Atkins because I don't think it's right for him, he likes beer too much. I tried to get him to do low calorie instead but he quit it for Atkins. Calorie counting is perceived as too much work to a lot of people, though I think it isn't unless you eat out a lot where you can't get the calorie info or where you have to estimate so much that it becomes useless data. Low carb works for me but I sometimes count calories on top of it or cheat.
