Users Discontinuing Anti-Obesity Injections Put On Weight Four Times Faster Than People Using Diet and Exercise

Fresh analysis suggests that individuals who discontinue popular weight-loss injections like semaglutide or tirzepatide can put back on lost weight far faster than those who stop traditional diet and exercise regimens.

Findings released in a major health publication shows that while obese individuals often shed about a fifth of their total mass while using the jabs, the mass comes back at an estimated rate of nearly a kilo each month once they quit.

"People buying these treatments need to be cognizant of the danger of rapid rebound weight gain when the therapy concludes," warns researcher Dr. Susan Jebb.

This pace of recovery means a reversion to pre-treatment mass within about one and a half years.

Weighing Therapies

The study, which examined dozens of studies involving over 9,000 of patients, contrasted the effects of these new drugs with conventional dieting.

The team emphasize that people who lose weight through diet and exercise generally have a more gradual creep back—perhaps 100 grams monthly—after stopping.

Explaining the Fast Regain

Doctors suggest the mechanism of the drugs is key to understanding the accelerated regain.

These medications mimic a natural hormone called GLP-1, which controls hunger.

"Long-term administration of the hormone levels several times higher than normal could lead to the body to produce less of its endogenous hormone, and may also reduce sensitivity to its actions," explained Dr. Adam Collins, a nutrition expert.

"Discontinuation of this medication results in appetite is unsuppressed, making overeating a significant risk."

A Chronic Disease?

The NHS advise the jabs for people with weight-linked health risks, alongside prescribed diet and exercise modifications.

A number of clinicians argue that, considering the high risk of weight regain, the therapy might need to be life-long.

This perspective is reinforced by drug manufacturers, who say that the findings "underscore the persistent character of excess weight," akin to managing diseases like high blood pressure.

Patient Accounts

People who have discontinued the jabs describe a sudden return of appetite.

"I experienced a trigger flipping and I was suddenly starving," said a patient.

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

Widespread Use

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

• Adoption is greater among females compared to males.
• The 40s and 50s demographic shows the highest level of interest.
• A large proportion obtain the drugs through private prescriptions rather than the NHS.

Finally, experts stress that while these medications are potent agents for weight loss, they are not a standalone cure and maintained weight loss relies on integrated lifestyle support.
