Ever wonder why sometimes you feel full and other times you can't stop eating? The answer lies in the intricate workings of your body's hormones. Let's dive into how hormones like ghrelin, leptin, and those in your intestines, such as CCK, PYY, and GLP-1, regulate hunger and fullness.
What are Hormones?
Have you ever wondered what hormones are? These chemical messengers travel through your bloodstream, reaching various tissues and organs to help regulate functions such as growth, metabolism, and mood. How do specific hormones influence your brain's signals about when to eat and when to stop, particularly concerning hunger and satiety?
What are Ghrelin and Leptin?
Ghrelin: Have you ever felt those hunger pangs that make you reach for a snack? That's ghrelin at work. This "hunger hormone" is produced in your stomach and signals your brain that it’s time to eat.
Leptin: Do you know the feeling of being satisfied after a meal? That's leptin, the "satiety hormone," which is produced by fat cells and tells your brain when you’re full. How balanced are these hormones in your body?
How Do Intestinal Satiety Hormones Work?
CCK (Cholecystokinin): Did you know that eating fat and protein releases CCK? This hormone helps you feel full after a meal.
PYY (Peptide YY): Are you aware that protein triggers PYY release in your intestines? This hormone reduces your appetite and helps keep you feeling satisfied.
GLP-1 (Glucagon-like Peptide-1): Ever noticed how you stay full longer after a high-protein meal? GLP-1, released in your intestines, slows digestion and makes you feel full.
Why is Protein So Important?
Unlike carbs that mainly affect GLP-1 or fats that influence both CCK and GLP-1, protein triggers all three key satiety hormones—PYY, GLP-1, and CCK. Until your body gets enough protein, it will keep signaling you to eat more. Are you getting enough protein in your diet?
What Does Research Say?
Studies show that people on a high-protein diet, even without calorie restriction, ate 30-50% fewer calories overall compared to those on a low-protein diet. This isn’t just a theory—it's backed by research. If you often feel hungry no matter how much you eat, could it be that your protein intake is too low?
What Can You Do?
To better manage your hunger, focus on getting enough protein. This can help regulate your hunger hormones and keep you feeling satisfied longer. How will you adjust your diet to include more protein?
