I used to weight twice what I do today, so I know a thing or two about eating too many calories, and I lost that weight so I know a thing or two about not eating that many calories.

Thing is, a rule like "only eat in an eight hour window" leaves plenty of time to consume huge amounts of calories. I've been known to pack away 4k+ in a meal, both in the past and today. It's not even hard for me. In fact, it's rather hard not to once I start eating because like many people who are of have been fat I'm a food addict.

Some here are saying things like "well, good luck eating 4k of lettuce dude!" and yeah, that is hard. But if you're eating lettuce and vegetables and all that low calorie stuff already you probably don't need the 8 hour window restriction!.
