Hey Michael. Just saying: I am one of the three percenters. Dumped 85 lbs thirty four years ago. Never came back, but it of course means that I have had to regularly shift and adapt my food choices as I age, and maintain my workouts. I’m a very serious athlete, so that’s not terribly hard, but the hard part was adapting to a much reduced caloric intake. For life. THAT is the part people can’t handle. What that does mean is that quality of those calories, those few we’re allowed if we wish to maintain, has to be very high, or else as you state we pay a very high price in our organs. LIke you I have done some pretty extreme adventures.
