Patients Discontinuing Anti-Obesity Injections Gain Back Weight Four Times Faster Than People Using Diet and Exercise

New research reveals that people who stop using blockbuster weight-loss injections like Mounjaro or Wegovy can put back on lost weight far faster than those who end traditional lifestyle plans.

Findings released in a prominent medical journal points out that while overweight individuals frequently drop a large proportion of their total mass while using the jabs, the weight is regained at an estimated rate of 0.8 kg per month upon discontinuation.

"People buying these medications need to be informed of the risk of fast weight regain when the treatment concludes," stated lead investigator Dr. Susan Jebb.

That rate of recovery means a reversion to original mass in about a year and a half.

Weighing Approaches

The study, which looked at 37 of trials involving thousands of participants, compared the outcomes of GLP-1 agonists with conventional dieting.

The team note that people who shed pounds through diet and exercise usually have a slower creep back—approximately 100 grams monthly—after stopping.

Explaining the Quick Rebound

Experts propose the mechanism of the injections accounts for the accelerated rebound.

The injections copy a body's own chemical called GLP-1, which moderates feelings of fullness.

"Sustained high doses of GLP-1 concentrations far above than the body's typical production may cause the system to produce less of its own natural GLP-1, and could reduce responsiveness to its effects," explained Dr. Adam Collins, a nutrition researcher.

"Withdrawal of this medication results in hunger is unsuppressed, making binge eating much more probable."

A Lifelong Condition?

Medical guidelines recommend the jabs for individuals with weight-linked health risks, alongside recommended diet and exercise modifications.

A number of clinicians argue that, due to the significant potential of weight regain, the therapy should be considered ongoing.

This perspective is supported by drug manufacturers, who note that the results "underscore the chronic nature of obesity," akin to managing diseases like high blood pressure.

Patient Accounts

Users who have discontinued the jabs explain a powerful return of cravings.

"I experienced a switch activating and I was suddenly starving," recalled an individual.

The struggle is compounded if users have not developed lasting dietary or behavioural modifications during therapy.

Significant Use

Survey data suggest that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with desire continuing to grow.

• Use is more common among females compared to men.
• The 40s and 50s age group shows the highest usage rates.
• Many access the drugs through private healthcare rather than public health services.

In conclusion, researchers caution that while the jabs are powerful tools for weight loss, they are not a magic solution and long-term success relies on combined behavioural management.
