> Intermittent fasting seems like it'd wreck your body if you do moderate to intense exercise. That just seems highly unlikely from an evolutionary perspective: food sources for most animal species tend to be inconsistent and require physical exertion to exploit (especially for predators). If hungry + physical exertion = damage, you'd expect that to get weeded out of the gene pool. Human populations have certainly gone through regular famines and starvation during our history, while still needing to farm manually.
