To add to this and provide anecdotal evidence, fbb is large tall Scandinavian germanic viking mix for his genetics, as his mother says depending on the century he would have been a beserker or a large farm boy named frans that spendt his names lifting hay bales and cows.In addition to overconsumption of calories he also indulged heavily in carbs which led to his state at the beginning of our experiments. Switching to a pure high fatty meat diet and a caloric deficit combined with his preference for heavy weight lifting means he was shedding pounds at a substantial rate. It's slowed down a bit but it's still in excess of expected loss even at the beginning of the experiment. Also the way his body deposited fat and builds muscle is odd to say the least.
