yes weight is complex. a factor of many things. in my opinion. but i do agree about sugar and added sugar. have you seen Food Inc? I liked that one as well. the food industry is so messed up. ive been eating healthier since the beginning of this year...part of my low tyrosine and phenylalynine diet, but also to eat less sugar.. stop drinking soda... eat more fruits and veggies. ..less gluten and dairy.
