Patients Coming Off Anti-Obesity Injections Regain Pounds Four Times Faster Compared to People Using Diet and Exercise
A recent study indicates that patients who come off new slimming jabs like Wegovy and Mounjaro can put back on lost weight at a significantly accelerated pace than those who stop conventional diet and exercise regimens.
Findings released in a major medical journal demonstrates that while overweight individuals frequently drop about a fifth of their body weight while on the medication, the mass comes back at an estimated rate of 0.8 kg per month upon discontinuation.
"People purchasing such drugs should be aware of the potential of rapid rebound weight gain when the treatment is stopped," warns lead investigator Dr. Susan Jebb.
That rate of recovery suggests a reversion to pre-treatment mass in about one and a half years.
Comparing Therapies
The research, which reviewed dozens of trials involving over 9,000 of participants, contrasted the outcomes of GLP-1 agonists with conventional dieting.
The team note that individuals who shed pounds through dieting usually see a more gradual creep back—around 0.1 kg a month—post-intervention.
The Reason for the Fast Rebound
Experts believe the way of the jabs explains the amplified rebound.
The injections mimic a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 levels far above than normal may cause the system to generate a reduced amount of its endogenous hormone, and may also lessen responsiveness to its actions," explained Dr. Adam Collins, a nutrition expert.
"Stopping of this medication means hunger is unsuppressed, making binge eating much more probable."
A Chronic Condition?
The NHS advise the injections for people with obesity-related health risks, alongside recommended lifestyle changes.
Professionals contend that, due to the likelihood of relapse, the treatment should be considered life-long.
This perspective is echoed by drug manufacturers, who state that the results "highlight the persistent character of excess weight," comparing it to managing diseases like diabetes.
Patient Accounts
Individuals who have stopped the jabs describe a intense resurgence of appetite.
"I experienced a trigger flipping and you're instantly ravenous," described one woman.
This difficulty is compounded if individuals have not developed lasting dietary or behavioural modifications during treatment.
Significant Use
Recent estimates show that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with demand being substantial.
- Use is higher among women than men.
- The middle-aged age group shows the highest level of interest.
- A large proportion obtain the medications through private prescriptions rather than the NHS.
Finally, researchers emphasize that while the jabs are potent tools for shedding pounds, they are not a magic solution and lasting health benefits likely depends on integrated lifestyle support.
