## In their own words

How each source describes the effect on appetite, and the diet it pairs with.

- **Mounjaro**: Appetite: "Mounjaro primarily works by regulating your appetite, giving you a sense of satiety (‘fullness’), making you feel less hungry and experience less food cravings." ([Mounjaro KwikPen patient leaflet](https://www.medicines.org.uk/emc/product/15481/pil)); Diet alongside: "Mounjaro is also used together with reduced-calorie diet and increased physical activity for weight loss" ([Mounjaro KwikPen patient leaflet](https://www.medicines.org.uk/emc/product/15481/pil))
- **Wegovy**: Appetite: "wegovy® works by acting on receptors in the brain that control your appetite, causing you to feel fuller and less hungry and experience less craving for food." ([Wegovy FlexTouch patient leaflet](https://www.medicines.org.uk/emc/product/13800/pil)); Diet alongside: "wegovy® should be used with a reduced calorie meal plan and increased physical activity." ([Wegovy FlexTouch patient leaflet](https://www.medicines.org.uk/emc/product/13800/pil))
- **NHS**: Appetite: "Tirzepatide works for weight loss by reducing your appetite and helping you feel fuller for longer." ([NHS: Tirzepatide](https://www.nhs.uk/medicines/tirzepatide/)); Diet alongside: "You'll need to eat a healthy, balanced diet while using semaglutide." ([NHS: Semaglutide](https://www.nhs.uk/medicines/semaglutide/))

## Meals and drinks

- **With or without food**: Mounjaro, Zepbound, Wegovy and Ozempic can each be injected at any time, with or without food, their leaflets and label say.
- **Tablets are different**: Rybelsus’s leaflet says fast at least 8 hours first, then wait at least 30 minutes before food, drink or oral medicines.
- **Alcohol**: The NHS says it’s best not to drink alcohol while you use it, as it can increase side effects like feeling or being sick.
- **Fluids when you’re sick**: If you’re sick or have diarrhoea, Mounjaro’s, Wegovy’s and Ozempic’s leaflets say drink fluids to prevent dehydration.
