I'm not sure if I get what you meant with the dark minute and collapsing, but here I come anyway: more often I eat, more often I get hungry. I'll try to put it this way - it's about being without(any) food for longer periods of time. After you break your fast, it doesn't really matter what and how much you eat. It's during the fast that the magic happens. Because most of the times you feel hungry, you're not. Not really. It's just your body running out of sugar supplies. And since your body is used to be fed first thing in the morning and last thing before bed, it won't even try to reach for fat supplies. It doesn't have to. Unless it's given a good reason, which is - you guessed it - fasting. Forcing the body to use fat as energy.

And after a while, you don't "force" it so much anymore. Your blood sugar levels drop to a minimum and you don't even feel hungry. You don't even feel the need for sugar.

But when you mess up and raise those glucose levels(by eating shit or eating too often), you're back to square one, which is, "forcing" the body to start burning fat for energy, or if you like it, dropping those glucose levels back to a minimum.

Hope that answered your question! And thank you for your amazing support!
