Individuals Discontinuing Anti-Obesity Jabs Gain Back Pounds Far More Rapidly Compared to Those on Conventional Diets

Fresh analysis suggests that individuals who come off new weight-loss injections like Wegovy and Mounjaro can put back on shed pounds much more quickly than those who stop traditional lifestyle plans.

Published data in a leading health publication points out that while overweight individuals can lose a large proportion of their total mass while using the jabs, the weight is regained at an estimated rate of nearly a kilo each month once they quit.

"Individuals buying these treatments should be informed of the risk of rapid rebound weight gain when the therapy concludes," warns lead investigator Dr. Susan Jebb.

That rate of regain suggests a return to original weight within about one and a half years.

Comparing Treatments

The research, which examined 37 of trials involving over 9,000 of patients, compared the effects of GLP-1 agonists with conventional dieting.

The team emphasize that people who lose weight through lifestyle changes alone usually see a more gradual weight regain—perhaps 0.1 kg a month—after stopping.

The Reason for the Quick Rebound

Doctors suggest the mechanism of the injections explains the amplified regain.

The injections copy a natural hormone called GLP-1, which helps regulate hunger.

"Long-term administration of the hormone levels several times higher than the body's typical production might result in the system to generate a reduced amount of its own natural hormone, and could lessen sensitivity to its actions," noted Dr. Adam Collins, a dietetics specialist.

"Stopping of this medication leads to hunger is unsuppressed, making excessive eating far more likely."

An Ongoing Issue?

Health authorities suggest the jabs for individuals with weight-linked health risks, accompanied by recommended lifestyle changes.

A number of clinicians say that, considering the significant potential of weight regain, the therapy is often long-term.

This opinion is supported by pharmaceutical companies, who state that the findings "underscore the long-term character of excess weight," akin to managing conditions like diabetes.

User Accounts

Individuals who have discontinued the medication describe a intense resurgence of cravings.

"It felt as if a trigger that goes on and I was suddenly starving," said a patient.

This difficulty is compounded if users have not adopted lasting lifestyle or habit changes during therapy.

Widespread Use

Figures suggest that millions of people in the UK have used weight-loss jabs in the last 12 months, with demand remaining high.

• Adoption is greater among females than men.
• The 40s and 50s age group shows the greatest usage rates.
• Many obtain the medications through private prescriptions rather than the NHS.

Finally, clinicians emphasize that while the jabs are potent agents for weight loss, they are not a permanent fix and lasting health benefits hinges on ongoing lifestyle changes.
