Dieting Fuels Binge Eating and Overeating

Let’s talk HUNGER HORMONES & APPETITE

.

What happens when you eat foods in a ‘normal’ situation when you are not on a diet?

.

Empty Stomach —> more grehlin (hunger) = increase appetite

.

Filling Stomach —> less grehlin, more CCK, GLP-1, PYY (satiety hormones) = reduce appetite so you stop eating. End of story and you get on with life as normal until your next meal.

.

Now what happens to your appetite when you’ve been on a diet?

.

You feel HUNGRIER when you’ve come off a diet :

  1. Both the satiety hormones (Leptin, CCK, GLP-1, PYY, Oxyntomodulin) AS WELL AS the hunger hormones (Grehlin, Neuropeptide Y) increase after we’ve deprived ourselves of food.

.

  1. The appetite stimulating hormones raise to a greater extent than the satiety producing hormones after being on a diet making patients feel HUNGRIER.

.

  1. Stress hormones (released during periods of dieting) increase appetite and increase intake of food.

.

  1. Once you start feeding yourselves with food again, insulin levels increase; thereby increasing fat synthesis and fat storage preferentially, as well as increasing cravings

.

  1. Serotonin & Dopamine (feel good hormones) get released after eating foods that are sugar-rich [when you go back to eating ‘normal’) and therefore provide a positive bio-feedback to the brain to consume more of these foods.
