Did you know exercise creates a chemical in your body that literally shuts down hunger signals? This means your workouts aren’t just burning calories — they’re flipping switches in your brain that control how hungry you feel.
I’m Deborah Maragopoulos, an integrative nurse practitioner, and I’ve spent decades studying how the hypothalamus — your body’s command center — controls weight, energy, and hormones.
Inside Your Brain Is a Tiny Gland Called the Hypothalamus
Two groups of hypothalamic neurons — agouti-related peptide neurons and the paraventricular nucleus— work like traffic lights for your appetite. Normally, AgRP neurons tell you to eat. But when you exercise, your body produces something called Lac-Phe. And Lac-Phe actually quiets those hunger neurons, which lets the paraventricular nucleus turn on and reduce your appetite.
That’s why sometimes after a really good workout, you don’t even feel hungry. Your brain chemistry is actively lowering your drive to eat.
So if you’re struggling with constant cravings, it’s not just about willpower. Your hypothalamus needs to be in balance so exercise can do its job.
Your Brain — Not Your Stomach — Decides How Hungry You Are
When your hypothalamus is supported, exercise becomes more effective for both appetite and weight balance. That’s why I created Genesis Gold® — to feed and balance your hypothalamus naturally.
