in your diet. “Eating too much sugar or flour makes insulin spike, then crash ― even after a large ‘healthy’ meal,” Dr. Hyman says.This puts the brake on your appetite, telling your brain, “Oh, I’m full. I don’t need any more food.” Leptin won’t work as well when you eat a lot of sugar, processed foods and flour.This “hunger hormone,” produced in your stomach, helps regulate your appetite.
It says, “I should eat ― I’m hungry!” and may spike when you’re sleep deprived, Dr. Hyman says.This hormone, made in your intestines, says, “Hey, I’m full! I’ve had enough to eat. I don’t need to eat any more.” Peptide YY levels may drop when you don’t get sleep.? This drives up cortisol , adding to your hunger, raising blood sugar and insulin, and starting a vicious cycle.If you binge time and time again, your body can’t burn those extra calories, Dr. Hyman says. So it stores them as fat.
