From the authors: "The fall in [core body temperature] in response to caloric restriction persists during the catch-up fat phase of refeeding conducted at typical laboratory room temperature (22°C) or at thermoneutrality (29°C). The reduced energy cost of homeothermy persisting during the dynamic phase of weight recovery could constitute a thrifty metabolic trait that contributes to the high metabolic efficiency underlying the rapid restoration of the body’s fat stores."
