I get that food/calories don’t have the same effect on everyone. For me, its a lot easier to gain than to lose weight. It’s very easy to overeat. In fact, I suspect the energy partition hypothesis is correct and even small amounts of simple carbohydrates make me gain weight fast. Nothing new here. But I was thinking: What is the relationship between gaining and losing weight? What is the ratio? Linear to sublinear or worse. Is it 1:0.8 or 1:0.5, probably.
