Users Stopping Slimming Jabs Put On Weight Far More Rapidly Than Those on Conventional Diets

Fresh analysis suggests that individuals who stop using blockbuster GLP-1 drugs like semaglutide or tirzepatide may regain reduced body mass far faster than those who end traditional lifestyle regimens.

Findings released in a major health publication shows that while obese people frequently drop a large proportion of their total mass while using the jabs, the mass is regained at an average rate of 0.8 kg per month once they quit.

"Individuals using such drugs need to be aware of the danger of quick rebound weight gain when the treatment concludes," stated expert Dr. Susan Jebb.

This pace of recovery implies a reversion to pre-treatment mass in about 18 months.

Analyzing Approaches

The study, which looked at 37 of studies involving thousands of patients, compared the effects of GLP-1 agonists with older methods.

Researchers note that people who shed pounds through lifestyle changes alone usually experience a less rapid creep back—around 100 grams monthly—post-intervention.

Understanding the Quick Rebound

Experts propose the mode of action of the drugs accounts for the accelerated rebound.

GLP-1 drugs copy a body's own chemical called glucagon-like peptide-1, which controls appetite.

"Artificially providing the hormone concentrations far above than normal might result in the system to produce less of its endogenous hormone, and could diminish responsiveness to its effects," said Dr. Adam Collins, a nutrition expert.

"Discontinuation of this hormone supplement results in appetite is unsuppressed, making excessive eating far more likely."

A Chronic Issue?

The NHS recommend the injections for people with weight-linked health risks, alongside prescribed lifestyle changes.

A number of clinicians argue that, due to the likelihood of weight regain, the therapy should be considered long-term.

This view is supported by pharmaceutical companies, who note that the results "underscore the long-term character of excess weight," akin to managing diseases like high blood pressure.

Patient Accounts

Users who have stopped the medication explain a sudden return of hunger.

"I experienced a trigger activating and you're instantly ravenous," recalled one woman.

The struggle is exacerbated if individuals have not adopted lasting lifestyle or habit modifications during treatment.

Growing Interest

Recent estimates show that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with demand continuing to grow.

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

Finally, clinicians emphasize that while the jabs are powerful tools for shedding pounds, they are not a standalone cure and lasting health benefits relies on combined lifestyle changes.
