Understanding Weight Loss Medications
August, 2025
Obesity affects more than 40% of US adults and is recognized as a chronic disease requiring long-term management. The introduction of GLP-1 medications has revolutionized weight management, creating significant opportunities and challenges for the food industry.
What is GLP-1?
GLP-1 (glucagon-like peptide-1) is a natural hormone released from cells in the small intestine. This hormone:
- Lowers blood glucose by triggering insulin release
- Slows digestion
- Increases feelings of fullness (satiety)
GLP-1 receptor agonist medications mimic these natural actions, reducing appetite and food intake, which results in significant weight loss.
