GLP 1 & Weight Loss

How Does Zepbound Help You Lose Weight

Zepbound helps you lose weight by mimicking two hormones that regulate appetite and blood sugar. The medication contains tirzepatide, which activates GLP-1 and GIP receptors in your body. These receptors slow gastric emptying, making you feel full longer after eating, and reduce food cravings by affecting brain appetite centers. Clinical trials showed patients lost an average of 15-20% of their body weight over 72 weeks. Zepbound also improves insulin sensitivity, helping your body process glucose more efficiently. The medication works best when combined with a reduced-calorie diet and increased physical activity, as it doesn't replace healthy lifestyle habits but makes them more achievable.
