Fast for 20 hours, eat for 4, then do whatever I want 1 day a week. I've lost 50 pounds and kept it off for 8 years. Any time I start to creep back up, I'll start fasting again. Magic.
What OP is referring to is intermittent fasting. In a 24 hour day, you don't eat or fast for x # hours and then allow yourself a time window of y # hours where you are allowed to eat. In OP's case, they are fasting for 20 hours and allow themselves a 4 hour time period per day where they can eat. It helps with a calorie deficit by limiting when you can eat, rather than mindless eating throughout the day. It can be a helpful tool for some.
It's possible to do, but harder than it seems. Especially if you add in requirements like getting a few cups of green veggies and a 100g of protein. That shit will fill you up fast!
Yeah, I suppose if you have the willpower to go through with it you're probably gonna do it the right way and not just get a huge plate of Chinese food
Sometimes I do just eat a huge plate of Chinese food, but I'll feel really gross after. It's like my body knows it needs the best food so I'm always craving green veggies and nuts
