Patients Discontinuing Slimming Jabs Put On Weight Four Times Faster Than Those on Conventional Diets

A recent study suggests that people who discontinue popular slimming jabs like semaglutide or tirzepatide tend to recover reduced body mass at a significantly accelerated pace than those who stop traditional lifestyle programs.

Published data in a major health publication shows that while obese individuals often shed substantial amounts of their body weight while using the jabs, the weight comes back at an estimated rate of 0.8 kg per month upon discontinuation.

"Users buying such treatments should be informed of the potential of fast rebound weight gain when the medication ends," warns expert Dr. Susan Jebb.

Such speed of regain suggests a return to pre-treatment mass within about one and a half years.

Weighing Treatments

The analysis, which looked at 37 of trials involving thousands of participants, contrasted the results of the injectable medications with other pills.

Scientists emphasize that people who lose weight through lifestyle changes alone typically have a slower weight regain—perhaps 0.1 kg a month—after stopping.

Explaining the Rapid Rebound

Doctors propose the mode of action of the drugs explains the amplified rebound.

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

"Long-term administration of GLP-1 levels far above than the body's typical production might result in the body to produce less of its endogenous hormone, and may also lessen sensitivity to its effects," said Dr. Adam Collins, a dietetics specialist.

"Stopping of this GLP-1 'fix' leads to appetite is unsuppressed, making overeating much more probable."

A Lifelong Disease?

Medical guidelines advise the injections for people with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.

Professionals contend that, considering the high risk of relapse, the therapy might need to be long-term.

This view is echoed by pharmaceutical companies, who note that the findings "highlight the long-term nature of excess weight," comparing it to managing diseases like high blood pressure.

User Experiences

Users who have come off the jabs report a powerful return of cravings.

"It felt as if a switch flipping and you become ravenous," recalled an individual.

This difficulty is exacerbated if patients have not established sustainable dietary or behavioural modifications during therapy.

Growing Use

Recent estimates suggest that a significant number of adults in the UK have tried these injections in the last 12 months, with desire remaining high.

• Use is greater among women compared to men.
• The 40s and 50s age group shows the greatest level of interest.
• Many access the drugs through private healthcare rather than the NHS.

Ultimately, clinicians stress that while these medications are powerful agents for shedding pounds, they are not a standalone cure and maintained weight loss likely depends on ongoing behavioural support.
