Incredible work. A few observations from someone who geeks out on this stuff:
Your visceral fat went from 187 to 54 in² — that's a 71% reduction and honestly that's where the real health transformation lives. Subcutaneous fat is cosmetic; visceral fat is what's driving metabolic disease.
The lean mass story is actually better than the headline suggests. At 312 lbs, a good portion of that "lean mass" was water retention, glycogen stores, and connective tissue that was only there to support a 312-lb frame. Functional lean mass (actual contractile muscle tissue) loss was probably closer to 12-15 lbs, which is very reasonable for 101 lbs total lost.
What does your lifting program look like now?
