Food, drink and alcohol

Mounjaro’s and Wegovy’s leaflets say they make you feel less hungry, and pair them with a reduced-calorie diet and more activity. The NHS says you’ll need a healthy, balanced diet, and that it’s best not to drink alcohol, as it can increase feeling or being sick.

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.

Questions

Mounjaro’s leaflet says it works by regulating your appetite and making you feel less hungry, and Wegovy’s says much the same.

Is there a set diet?

Patterns

Jabwise shows how your food noise is changing.

Each check-in asks how loud your food noise is. Then and Now sets your first 4 weeks beside your latest, and names a change only once the numbers bear it out.

Jabwise Then and Now: food noise quieter than at the start, quiet in 6 of 10 check-ins lately against none in the first four weeks
