GLP-1 Weight Loss
GLP-1 (glucagon-like peptide-1) is a hormone that plays a crucial role in blood sugar regulation and appetite control. GLP-1 receptor agonists—like semaglutide (Ozempic, Wegovy), liraglutide (Saxenda, Victoza), Mounjaro (tirzepatide) and others—are medications that mimic this hormone and are used for both type 2 diabetes and weight loss.
Here's how GLP-1 helps with weight loss:
1. Appetite Suppression
GLP-1 slows down the emptying of the stomach, making you feel full longer after eating. It also acts on the brain's appetite centers (like the hypothalamus), reducing hunger and food cravings.
2. Reduced Calorie Intake
By curbing appetite and promoting a feeling of satiety, people on GLP-1 medications often naturally eat fewer calories, which leads to weight loss over time.
3. Improved Insulin Sensitivity
GLP-1 enhances insulin secretion and suppresses glucagon (a hormone that raises blood sugar), helping maintain more stable blood sugar levels. This metabolic balance may indirectly support weight management.
4. Behavioral Reinforcement
People on GLP-1 medications often report fewer binge-eating episodes or reduced emotional eating, making it easier to adhere to healthier diets.
