What separates us from the reptiles is that we can get our body temperature UP by burning calories. If you run hot, you can only passively cool down by sweating lots or walking around naked, I guess. If you aren’t sweating lots, you aren’t losing significant excess heat. But the actual point of the OP is that many people who are even only 40 lb overweight already eat in excess of 150 kcal, never mind 50. If this is how ketosis works, they wouldn’t run super hot, but they would also never get to a normal weight. Also, you can achieve the same effect by exercising or even just drinking cold water. Think about how many people got thin by doing this.
BTW, when you drink tea etc, your body reduces heat production to compensate.
