Semaglutide is a medication initially developed to treat type 2 diabetes.

Semaglutide works for weight loss by affecting various mechanisms in the body, particularly related to appetite and food intake. When used at a higher dose than typically prescribed for diabetes, it has been shown to:

1. **Appetite Reduction:** Semaglutide influences the areas in the brain that regulate appetite, leading to a decrease in hunger and food cravings.
2. **Delayed Gastric Emptying:** The medication slows down the emptying of the stomach, which can contribute to a feeling of fullness, helping individuals eat less and reduce calorie intake.
3. **Increased Energy Expenditure:** It may also have an impact on energy expenditure, potentially enhancing the body’s ability to burn calories.

These combined effects make semaglutide an effective tool for weight loss.
