I agree with you about the troll bit... something just doesn't add up. But for fun, let's pretend for a moment that this post is real and this is actually happening to this obeast. I calculated its TDEE to be 2,134 kcal per day, based on its age (given), weight (given) and I assumed it is sedentary based on its "knee condishuns". I also assumed an average height of 5'4" since none was given in the original post. So if this thing ate 1200 kcal per day, it would be possible for it to lose about 100 lbs in a year. Also, if this thing has such bad knees, why doesn't it try a low-impact exercise, like bike riding? Both my sisters had major reconstructive surgery on both their knees (for a congenital defect) and biking was a huge part of their recovery. Also, one of my sisters has PCOS and isn't a butter golem, so I don't buy the "PCOS makes you fat" bullshit.
