i don't have any documented (i.e. blood tests) to prove my improved self, but i'll tell you what i do know.
eating low carb has leveled out my moods. i have always been called a swinger (moods ) now, i'm pretty much even.
my skin has improved. i have been cursed over the last year and a half with cystic acne. since low carbing, not a one.
don't know if it counts, but my motivation is stronger. choosing not to eat sugar/starches is very easy now.
i have lost a little weight, but not in the typical way i have in the past. my weight (fat) loss has been from all over this time, not just starting in my chest and moving down. my backside and thighs would always be the last to lose, now it's not like that.
and last but not least, the major benefit of lc is having this forum to vent, congratulate, inform, ask, and laugh with ya'll.
regards,
brenda
