Users Coming Off Anti-Obesity Medications Put On Pounds Four Times Faster Compared to People Using Diet and Exercise

New research suggests that individuals who discontinue popular weight-loss injections like Mounjaro or Wegovy may regain shed pounds much more quickly than those who end conventional diet and exercise plans.

Research printed in a leading medical journal demonstrates that while obese people often shed a large proportion of their total mass while undergoing treatment, the weight is regained at an estimated rate of nearly a kilo each month after stopping.

"Individuals purchasing such medications need to be cognizant of the risk of quick weight regain when the treatment ends," cautioned lead investigator Dr. Susan Jebb.

This pace of regain implies a return to pre-treatment mass in about one and a half years.

Comparing Treatments

The research, which examined 37 of trials involving over 9,000 of participants, contrasted the outcomes of the injectable medications with older methods.

Researchers note that individuals who lose weight through diet and exercise typically see a more gradual weight regain—perhaps 0.1 kg a month—post-intervention.

The Reason for the Rapid Rebound

Experts suggest the way of the injections explains the accelerated regain.

GLP-1 drugs copy a natural hormone called GLP-1, which helps regulate feelings of fullness.

"Artificially providing the hormone concentrations several times higher than the body's typical production might result in the body to produce less of its own natural hormone, and could reduce sensitivity to its effects," noted Dr. Adam Collins, a nutrition researcher.

"Stopping of this medication results in appetite is unsuppressed, making excessive eating a significant risk."

A Lifelong Issue?

The NHS recommend the injections for people with obesity-related health risks, alongside prescribed lifestyle changes.

Professionals contend that, given the significant potential of relapse, the therapy is often ongoing.

This perspective is supported by pharmaceutical companies, who say that the results "underscore the persistent character of excess weight," comparing it to managing conditions like hypertension.

Patient Accounts

Individuals who have stopped the jabs report a intense return of cravings.

"It felt as if something activating and you're instantly extremely hungry," described a patient.

This difficulty is compounded if users have not developed sustainable dietary or behavioural modifications during treatment.

Growing Use

Survey data indicate that a significant number of adults in the UK have tried these injections in the last 12 months, with desire continuing to grow.

• Use is more common among females than men.
• The middle-aged age group shows the greatest usage rates.
• Many obtain the drugs through private healthcare rather than the NHS.

In conclusion, researchers stress that while the jabs are effective tools for shedding pounds, they are not a standalone solution and long-term success likely depends on ongoing behavioural changes.
