Fasting, both intermittent (< 24 hr) and extended, are increasingly being recognized as powerful tools to lose weight and cure/prevent diet-related conditions like diabetes and metabolic disorder, thanks to the work of people like Drs. Peter Attia and Jason Fung. In my experience IF is an easy way to cut out excess calories, and EF gives me amazing energy and mental clarity, while helping me have a healthier relationship with food. My simplistic view on fasting is that my body stored all that excess energy as fat for the purpose of being used when food is not so readily available, a situation that may have been common in the not-too-distant past but just doesn't happen for me or most Americans today; therefore it's incumbent on me to restrict food occasionally and let the body use these stores, while performing other maintenance that is limited when digestion is occurring (notably autophagy). Note: when I refer to fasting I mean water-only (also non-caloric drinks like tea and coffee), with electrolyte supplementation for extended fasts.

I'm not an anthropologist of biologist, but I think modern life is basically incompatible with how humans evolved. I mean, we are hunters. If we do not spend the the energy to hunt what we eat, it seems clear that we get obese. Our natural instincts tell us to eat as much as we can whenever food is available. This is because we evolved without any guarantee of frequent meals. Post food-scarcity society seems basically against our natural instincts.

Compounding the problem, we've identified what activates these instincts (fat and sugar), and hyper-optimized food to target the reward centers and cause people to eat _even more_ food that they don't need. Then we use what we've learned about psychology to trigger people's desire for food even when they're not eating. Then we invent expensive drugs (see TFA) to help people lose the weight (and throw commercials at them for _those_)...

  Obesity rates started soaring only in the later 20th century. I'm suspicious of explanations for recent and rapid upward obesity trends that cite our evolutionary history from before the Neolithic Revolution. Human genetics did not undergo a massive shift in the last couple of generations. We did not just recently transition away from nomadic hunting lifestyles either. No single factor seems to line up with increasing obesity rates well enough to be blamed as The Cause. I think it may be a combination of small nudges that form strongly obesity-promoting environments.

    Marketing for unhealthy foods is a 20th century thing. And marketing something as healthy when it's actually not (fat free craze of yesteryear). To me it seems this is one of the major problems. Lack of education on healthy eating, damaging advertising, and a lack of regulation around food labeling.
