Patients Stopping Weight-Loss Jabs Put On Pounds Four Times Faster Compared to People Using Diet and Exercise

A recent study indicates that individuals who stop using blockbuster weight-loss injections like semaglutide or tirzepatide can put back on shed pounds much more quickly than those who halt traditional lifestyle programs.

Findings released in a leading health publication shows that while obese individuals often shed substantial amounts of their total mass while using the jabs, the weight is regained at an estimated rate of 0.8 kg per month once they quit.

"Individuals purchasing such drugs must be cognizant of the danger of fast rebound weight gain when the medication ends," cautioned expert Dr. Susan Jebb.

That rate of recovery means a reversion to starting mass within about one and a half years.

Weighing Treatments

The study, which reviewed 37 of trials involving over 9,000 of patients, compared the effects of the injectable medications with conventional dieting.

The team emphasize that individuals who lose weight through lifestyle changes alone typically experience a more gradual creep back—around 0.1 kg a month—after stopping.

Explaining the Fast Rebound

Experts propose the mechanism of the injections is key to understanding the amplified rebound.

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

"Long-term administration of GLP-1 levels far above than the body's typical production could lead to the body to produce less of its endogenous GLP-1, and could reduce responsiveness to its actions," said Dr. Adam Collins, a dietetics researcher.

"Withdrawal of this hormone supplement leads to hunger is unsuppressed, making overeating a significant risk."

A Lifelong Disease?

Medical guidelines suggest the injections for people with obesity-related health risks, alongside recommended diet and exercise modifications.

Professionals say that, due to the significant potential of weight regain, the treatment might need to be long-term.

This view is supported by drug manufacturers, who state that the findings "highlight the persistent nature of excess weight," akin to managing conditions like diabetes.

User Experiences

People who have come off the jabs explain a powerful return of appetite.

"It was like something that goes on and you're instantly starving," described an individual.

This challenge is worsened if patients have not developed permanent dietary or behavioural modifications during treatment.

Significant Use

Recent estimates show that millions of people in the UK have used these injections in the last 12 months, with desire being substantial.

• Use is greater among women compared to males.
• The middle-aged age group shows the greatest level of interest.
• A large proportion access the drugs through private healthcare rather than public health services.

Finally, clinicians emphasize that while the jabs are potent tools for shedding pounds, they are not a permanent cure and long-term success relies on ongoing lifestyle support.
