Users Coming Off Weight-Loss Medications Put On Weight Far More Rapidly Than People Using Diet and Exercise

Fresh analysis reveals that people who discontinue new slimming jabs like semaglutide or tirzepatide can put back on reduced body mass at a significantly accelerated pace than those who stop traditional lifestyle programs.

Findings released in a prominent health publication shows that while overweight individuals often shed a large proportion of their body weight while undergoing treatment, the weight comes back at an estimated rate of 0.8 kg per month once they quit.

"People buying such treatments need to be aware of the risk of quick rebound weight gain when the medication concludes," cautioned researcher Dr. Susan Jebb.

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

Comparing Therapies

The research, which reviewed dozens of studies involving over 9,000 of participants, compared the effects of these new drugs with older methods.

Researchers note that people who lose weight through dieting usually have a more gradual creep back—perhaps 0.1 kg a month—post-intervention.

Explaining the Quick Regain

Nutrition scientists propose the mode of action of the injections is key to understanding the amplified regain.

The injections mimic a body's own chemical called GLP-1, which moderates appetite.

"Long-term administration of GLP-1 concentrations several times higher than the body's typical production might result in the body to produce less of its endogenous GLP-1, and may also reduce responsiveness to its actions," noted Dr. Adam Collins, a nutrition specialist.

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

A Lifelong Issue?

Health authorities suggest the injections for individuals with obesity-related health risks, accompanied by prescribed diet and exercise modifications.

A number of clinicians argue that, considering the likelihood of relapse, the therapy should be considered long-term.

This perspective is reinforced by drug manufacturers, who note that the findings "highlight the persistent nature of obesity," similar to managing conditions like diabetes.

User Experiences

People who have stopped the jabs explain a powerful resurgence of hunger.

"It was like a switch activating and you're instantly starving," said one woman.

This challenge is compounded if users 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 past year, with interest being substantial.

• Use is greater among females than males.
• The middle-aged demographic shows the greatest usage rates.
• Many access the drugs through private prescriptions rather than public health services.

Ultimately, researchers stress that while the jabs are effective tools for shedding pounds, they are not a magic fix and maintained weight loss relies on combined lifestyle changes.
