Exact. The main point is that modern diet heavely based on PUFA (vegetable oil) is interfering with metabolic level and thermogenesis. Basically all hibernating mamalian are inducing hibernation metabolism and fat storage due to high availability of seeds/grains (vegetable oil) and sugar during summer. The legacy of our hibernating ancestor hits us hard as far as adopting high unsaturated fat diet like modern diet is triggering fat storage reaction and lowering thermogenesis at cells level by modifying chemical reaction of mithochondrie. Common Torpor during daylight is one of the numerous symptoms of lower metabolic rate. All this to prove that one calorie is not equal to another calorie outside the scope a physical rules of thermodinamic in order to increase the temperature of one liter of water by 1 degree celsius. Living organism are not just water, and bio-chemistry is far more complex than those radical reducting stupid dogma.
