Users Coming Off Anti-Obesity Medications Put On Weight Four Times Faster Than People Using Diet and Exercise

A recent study indicates that people who discontinue new GLP-1 drugs like Wegovy and Mounjaro may regain reduced body mass at a significantly accelerated pace than those who stop traditional diet and exercise regimens.

Published data in a leading medical journal points out that while obese people 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 after stopping.

"Individuals buying these treatments should be aware of the risk of fast rebound weight gain when the therapy is stopped," stated expert Dr. Susan Jebb.

Such speed of recovery suggests a return to pre-treatment weight in about 18 months.

Comparing Treatments

The analysis, which examined dozens of studies involving over 9,000 of patients, compared the effects of these new drugs with older methods.

The team note that individuals who shed pounds through lifestyle changes alone usually see a less rapid weight regain—around 0.1 kg a month—once they finish.

Understanding the Rapid Regain

Doctors suggest the way of the drugs is key to understanding the heightened regain.

GLP-1 drugs imitate a natural hormone called glucagon-like peptide-1, which controls appetite.

"Sustained high doses of GLP-1 concentrations several times higher than normal may cause the system to produce less of its own natural GLP-1, and could lessen sensitivity to its actions," explained Dr. Adam Collins, a dietetics specialist.

"Withdrawal of this GLP-1 'fix' leads to appetite is unsuppressed, making excessive eating far more likely."

A Chronic Issue?

Medical guidelines advise the injections for people with weight-linked health risks, accompanied by prescribed diet and exercise modifications.

Professionals say that, given the likelihood of weight regain, the treatment is often ongoing.

This perspective is echoed by drug manufacturers, who state that the findings "highlight the persistent character of obesity," comparing it to managing conditions like hypertension.

Patient Accounts

People who have stopped the medication describe a powerful return of hunger.

"I experienced a switch that goes on and you become ravenous," recalled one woman.

This difficulty is exacerbated if users have not adopted permanent lifestyle or habit changes during therapy.

Widespread Use

Recent estimates indicate that millions of people in the UK have tried these injections in the past year, with interest continuing to grow.

• Use is more common among females compared to men.
• The 40s and 50s demographic shows the highest level of interest.
• A large proportion access the drugs through private prescriptions rather than the NHS.

In conclusion, researchers stress that while these medications are potent tools for shedding pounds, they are not a magic solution and long-term success likely depends on combined lifestyle support.
