Patients Coming Off Slimming Injections Put On Pounds at a Quadrupled Rate Compared to People Using Diet and Exercise

A recent study indicates that people who come off new weight-loss injections like semaglutide or tirzepatide tend to recover reduced body mass far faster than those who halt conventional lifestyle programs.

Findings released in a major health publication points out that while obese individuals often shed a large proportion of their body weight while on the medication, the mass returns at an estimated rate of 0.8 kg per month once they quit.

"People buying these medications should be cognizant of the risk of quick rebound weight gain when the medication concludes," warns researcher Dr. Susan Jebb.

This pace of recovery means a reversion to original weight in about 18 months.

Analyzing Approaches

The study, which examined dozens of trials involving thousands of patients, compared the outcomes of these new drugs with older methods.

Researchers note that people who shed pounds through dieting typically experience a more gradual weight regain—perhaps 0.1 kg a month—after stopping.

Understanding the Fast Regain

Doctors believe the way of the injections accounts for the heightened rebound.

The injections copy a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.

"Artificially providing the hormone concentrations far above than normal may cause the body to produce less of its own natural GLP-1, and could diminish sensitivity to its actions," noted Dr. Adam Collins, a dietetics researcher.

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

An Ongoing Disease?

Health authorities suggest the jabs for individuals with weight-linked health risks, alongside prescribed lifestyle changes.

Many experts say that, due to the likelihood of relapse, the treatment might need to be life-long.

This view is echoed by drug manufacturers, who state that the results "highlight the long-term character of excess weight," similar to managing conditions like hypertension.

Patient Experiences

Users who have come off the medication report a powerful resurgence of appetite.

"It was like a switch flipping and you're instantly ravenous," recalled a patient.

The struggle is compounded if patients have not adopted sustainable lifestyle or habit modifications during therapy.

Widespread Use

Figures show that millions of adults in the UK have used these injections in the last 12 months, with demand being substantial.

• Adoption is more common among women compared to men.
• The 40s and 50s age group shows the highest usage rates.
• Many access the medications through private healthcare rather than the NHS.

Finally, researchers stress that while these medications are powerful tools for weight loss, they are not a magic cure and maintained weight loss relies on integrated lifestyle changes.
