I've been on the LCHF diet since April and have lost 1 1/2 stone quite easily so I know it works. I understand that by eating low carb my body gets it's energy from the stored fats but what about the high numbers of calories in the fat I'm eating? Am I burning those as well or are they somehow being ignored in favored the stored fats? I'm sure I'm eating more calories than I would have before so there must be some 'trickery' going on.
