Presumably because carrying surplus fat has minimal cost relative to the evolutionary likelihood of famine. This is more obvious than the muscle scenario. For muscle, prior to the famine you get to do cool things like punch your neighbor and do pull ups. During a famine, you could consume your muscles as calories. Where is the cost?
- bluedino 9y agoIf your body fat percentage is too low, you'll run into side effects (including reproductive ones)
- dpark 9y agoDuring a famine your fat neighbor will survive longer. Storing fat is more efficient than building muscle. Maintaining fat is more efficient than maintaining muscle. And metabolizing fat is more efficient than metabolizing muscle. So while it's cool that you can do pull-ups, your fat neighbor will easily outlast you in a famine unless you're willing to eat him.
