Keeping off the weight you lost
- Talk with your prescriber first, so your plan covers follow-up visits plus any other medicines.
- Keep the habits you built while taking the drug. Include protein at each meal, eat smaller portions, and have fewer sugary drinks.
- Keep moving. Strength training helps protect the muscle you have now.
- Use a set schedule to weigh yourself. Agree in advance on the amount of change that means you call your prescriber.
- If you take it because of diabetes, ask how your blood sugar will be managed after you stop.
