I have non-diabetic hypoglycemia, inherited from my mom. So I process sugar quickly and if I don't eat for too long, it can cause confusion, dizziness, wobbly muscles, I basically become an incoherent catatonic mess. As a result, I can eat a ton of sweets and not gain an ounce. I also sweat easily so my weight fluctuates some between winter and summer. I do exercise twice each day and my job requires lots of lifting so combined with my inhuman ability to process sugar, I have an above average build. With a little self control I could be positively olympian but I would have to find a good substitute for processed sugars to maintain normal functions. Maybe fruit? So yea, sweets as necessary combined with meats and protein bars as I intend to drop at least 2 pant sizes by May or swap the fat for muscle, however it works out.
