Intermittent fasting has been the best trend, because it validates my irresponsible meal-skipping lifestyle! Don't feel like eating breakfast every day since you were thirteen? Cool, now my first meal is at noon! Eat dinner at 6:00 when you get home from work? Great, I only ate in a six hour window today!
N=19 is not reassuring. But hey it worked on 397 mices : https://www.cell.com/cell-metabolism/fulltext/S1550-4131(14)00498-7 Any excuse to not have 3meals a day is good. Now let try to get back to 2 sleep a day : http://theconversation.com/did-we-used-to-have-two-sleeps-rather-than-one-should-we-again-57806
Without really planning it, I decided to listen to the hungry one on me and I realized I am not hungry when I wake up. I used to have a heavy breakfast out of habit, and then feel actual hunger around noon. Now I drop the breakfast and I don't feel hungry till noon... Also, noticed that if I eat right before bed, I have nightmares and sleep bad (was diagnosed with sleep apnea last year). So I don't eat later than 8/9pm. Without really planning, I am doing some kind of intermittent fasting, I guess? I lost some weight, but not a lot. Will see how this develops with time.
My boss has been doing a version of this along with a new circadian rhythm thing, and it's working for him. He is a HARD CORE data geek, pretty dang fit, and wants to just lose the last few pounds. The combination of fasting-plus-Circadian-thingie has allowed him to eat literally anything he wants, and as much of it as he wants (McDonald's, pizzas, etc.), and still lose 6 pounds over a 2-week period including the Thanksgiving holiday. He tracks HUNDREDS of metrics and has been "hypermiling" his body for years. This latest experiment is kinda blowing his mind, and shaking a lot of what he thought he knew. He's still got 6 more weeks of data to gather and then process, but from all early indications, the circadian/fasting thing is working in every metric, including productivity, sleep quality, and overall vitality. It's kinda nuts.
