The truth is most people are weight-stable most of the time. Even obese folks and famine victims stay within a narrow range for years at a time despite spontaneous/variable food. (When I used to plot 7-day kcal against weight change the relationship was very weak).
So there's a lot of homeostasis at work and any influence that overpowers it probably needs to be a substantial toxin or deficiency. Assuming the body will always reconcile energy balance with adipose influx/efflux is a mistake.
