Users Coming Off Anti-Obesity Jabs Regain Weight Four Times Faster Than People Using Diet and Exercise

A recent study suggests that people who come off popular slimming jabs like Mounjaro or Wegovy can put back on reduced body mass far faster than those who stop conventional lifestyle regimens.

Findings released in a major health publication points out that while obese people often shed about a fifth of their total mass while using the jabs, the weight comes back at an estimated rate of 0.8 kg per month after stopping.

"Individuals purchasing these drugs need to be cognizant of the danger of fast rebound weight gain when the treatment ends," stated researcher Dr. Susan Jebb.

Such speed of regain suggests a return to pre-treatment weight in about 18 months.

Weighing Treatments

The research, which examined dozens of studies involving over 9,000 of patients, contrasted the effects of the injectable medications with older methods.

Scientists emphasize that people who shed pounds through lifestyle changes alone usually see a more gradual creep back—around 100 grams monthly—post-intervention.

Understanding the Quick Regain

Doctors believe the way of the drugs accounts for the heightened rebound.

GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which moderates hunger.

"Artificially providing GLP-1 concentrations far above than normal might result in the body to generate a reduced amount of its own natural GLP-1, and could lessen responsiveness to its actions," noted Dr. Adam Collins, a nutrition researcher.

"Withdrawal of this medication means hunger is unsuppressed, making binge eating far more likely."

A Chronic Issue?

Medical guidelines suggest the injections for people with weight-linked health risks, accompanied by recommended lifestyle changes.

A number of clinicians contend that, given the likelihood of weight regain, the treatment might need to be life-long.

This view is reinforced by pharmaceutical companies, who say that the findings "highlight the chronic nature of obesity," similar to managing diseases like high blood pressure.

Patient Accounts

People who have come off the medication report a sudden return of appetite.

"It felt as if something flipping and I was suddenly extremely hungry," recalled one woman.

The struggle is exacerbated if users have not adopted lasting lifestyle or habit changes during therapy.

Growing Interest

Survey data show that a significant number of adults in the UK have used weight-loss jabs in the past year, with desire remaining high.

• Use is higher among women than men.
• The middle-aged age group shows the greatest usage rates.
• Many access the medications through private prescriptions rather than public health services.

Ultimately, researchers stress that while these medications are powerful tools for weight loss, they are not a standalone solution and lasting health benefits hinges on integrated behavioural changes.
