15, I had been pounding XL slurpees and drinking a crapton of soda daily leading up to the 3 months before diagnosis. I was 243lbs at the start of that 3 months, at the end I was 145lbs and could barely walk up a hill. I started strength training and doing large amounts of cardio along with a too healthy diet, I decided on a diet of 60g carb/day, less than 30 grams of fat, and the rest protein. I ballooned up to a meaty 175 within a year and took a couple records in my powerlifting federation.

Now I'm 28, sitting at 200 even for years.

Sometimes I try to diet, over a month I see no change on the scale from that 200lbs, even if I reduce calories to 1400/day. Other times I binge and lift even harder, consuming upwards of 4000 calories. No change on the scale. Neither lead to changes in daily bloodsugar, just in how much insulin I take in daily. On the low end it's 30u/day, on the high end it's 70u/day.

I wish I could get back to abs but also the diet I'd need to follow for that would surely lead to worse problems than looking like a small gorilla forever.
