Another anecdote, but others might find it useful: I have been doing intermittent fasting for years now. I currently eat once per day. My eating window is usually an hour or less. I eat dinner, have dessert, go to bed. I run five miles every morning on an empty stomach. During the day I drink only water and I put an electrolyte fizzy tablet in my first glass. It works great for me for maintaining my energy level and managing my weight. It probably does not work for everybody, but I think more people should try it. Most humans currently living and who have lived didn't eat three meals every day. It's a recent phenomenon driven by those marketing food and snacks. Observing obesity rates, more people should try hunger and learn how to manage it. I should add: I do occasionally have breakfast and lunch meetings or social engagements at which I feel compelled to eat or have a treat. I find that once I break my fast for the day, my hunger is awakened and it is harder to abstain.
