The final phase needs a plan too
Stopping treatment and reducing weight-regain risk
Appetite and biological pressure to regain weight can return after Wegovy or Mounjaro is stopped. Preparing month by month with a specialist medical team helps turn temporary changes into a realistic long-term maintenance plan.

What clinical withdrawal studies foundSTEP 1 extension SURMOUNT-4
Weight regain is not a failure of willpower
The medicine’s appetite-regulating effect does not permanently rewrite every biological driver of weight. Trial averages do not predict one person’s exact outcome, but they explain why maintenance should be planned before the final injection.
After semaglutide withdrawal
About two-thirdsParticipants regained approximately two-thirds of their prior semaglutide-associated weight loss during the year after treatment and lifestyle intervention were withdrawn.

A month-by-month medical maintenance plan
Establish the baseline
Confirm why treatment is ending. Record weight, waist, blood pressure, appetite, current dose, side effects, relevant blood results, medicines and the routines that have worked.
Protect the daily structure
Plan regular meals, adequate protein and fibre, hydration, resistance and aerobic activity, sleep and a consistent—not obsessive—weighing schedule. Review returning hunger early.
Review the trajectory
Compare weight and waist trends rather than one measurement. Adjust the nutrition and activity plan, assess sleep and mood, and review blood pressure or glucose where clinically relevant.
Act before a small change becomes a large one
Agree in advance what upward trend or symptom should trigger contact. The next step may be coaching, investigation of another cause, medicine review or reassessment of a clinical treatment pathway.
Specialist follow-up
The objective is to finish with skills—not simply finish the injections
Monthly progress reviews can help patients practise meal planning, recognise hunger and fullness, improve food quality, build strength and aerobic capacity, protect sleep and prepare for holidays, stress and disrupted routines.
This support can improve the maintenance plan, but it cannot guarantee that no weight will return. Early review is important if appetite rises sharply or weight and waist measurements show a sustained upward trend.

Decide why and when treatment is ending
Pregnancy planning, side effects, inadequate benefit, cost, availability or a change in health can require different clinical plans. Do not simply stop because the current pen has finished.
Agree what will be monitored
Weight and waist are part of the picture. Blood pressure, glucose, lipids, sleep, appetite, eating patterns, activity and other weight-related conditions may also need follow-up.
Define the response to regain
Agree when to contact the team and what will be reviewed. A sustained increase should prompt assessment, not shame or extreme dieting.

Safety first
Do not restart leftover pens at an old dose
After a treatment break, suitability and tolerability need reassessment. Restarting a previous high dose can increase the risk of adverse effects.
Call 112 for a life-threatening emergency.
Common questions
Stopping treatment and weight regain: questions
Will everyone regain weight after stopping?
No, individual outcomes vary, but clinical withdrawal studies show that weight regain is common enough to require a planned maintenance strategy.
Can healthy habits guarantee that I will not regain weight?
No strategy can guarantee this. Nutrition, activity, sleep and follow-up can support maintenance, while biology, medical conditions and medicines also influence weight.
Do Wegovy or Mounjaro need to be tapered?
Do not create a taper yourself. The doctor decides how treatment should end or change based on the medicine, reason for stopping, response and current symptoms.
Why can hunger return after treatment stops?
The appetite-regulating effect of the medicine diminishes after treatment ends, so hunger and food thoughts may increase again.
How often should I check my weight?
Use a regular schedule agreed with the clinical team rather than reacting to daily fluctuations. Weight and waist trends are more informative than a single reading.
What should trigger an earlier review?
A sustained upward weight or waist trend, rapidly increasing hunger, loss of routine, worsening blood glucose or blood pressure, or distress about eating should prompt review.
Can I restart treatment later?
Possibly, after a new medical assessment. Never restart leftover pens or a previous high dose after a break without advice.
What monitoring may continue after stopping?
Depending on individual risk, follow-up may include weight, waist, blood pressure, glucose or HbA1c, lipids, nutrition, physical activity and other medical conditions.
