Okay I see metabolism up for debate a lot in here with a lack of hard sources, so

Endotherms are commonly known as "warm-blooded," meaning that they get their warmth from their body through their metabolism. It's commonly known that fat can be used for insulation in cold environments because it's a lot harder for heat to leave lots of layers/cold to enter lots of layers. Lighter endotherms would need more calories to regulate their body temperature than heavier endotherms. To quote my textbook directly, "as body size increases, energy costs per gram of tissue decrease, but an ever-larger fraction of tissue is required for exchange, support, and locomotion" (Reece and others 870). This means that fat cells require less energy to sustain than actual bigger structures

I think my psychology book can explain this better than I can:
"Once we become fat, we require less food to maintain our weight than we did to attain it. Why? Because compared with other tissue, fat has a lower metabolic rate--it takes less food and energy to maintain body weight within a higher-than-average range. When weight drops below this set-point (often considered a settling-point range of weight rather than a precise number of pounds), the person's hunger increases and metabolism decreases. Thus, the body adapts to starvation by burning off fewer calories, and to extra calories by burning off more" (Myers 584).

Don't worry about /u/RampagingKoala, his estrogen supply is running a bit low so he's unable to do basic things like googling. Here's the book you were referencing, fam.
