Individuals Coming Off Anti-Obesity Medications Regain Weight Four Times Faster Compared to People Using Diet and Exercise

New research indicates that people who discontinue popular slimming jabs like Wegovy and Mounjaro can put back on reduced body mass far faster than those who end conventional lifestyle regimens.

Research printed in a major health publication points out that while obese people frequently drop a large proportion of their body weight while on the medication, the weight returns at an estimated rate of 0.8 kg per month once they quit.

"People buying these medications should be cognizant of the potential of quick weight regain when the therapy ends," cautioned researcher Dr. Susan Jebb.

That rate of recovery suggests a return to original weight in about a year and a half.

Comparing Therapies

The analysis, which looked at dozens of trials involving thousands of patients, compared the effects of GLP-1 agonists with older methods.

The team emphasize that people who lose weight through diet and exercise usually have a slower creep back—perhaps 0.1 kg a month—after stopping.

The Reason for the Quick Regain

Experts suggest the way of the drugs accounts for the heightened regain.

GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.

"Long-term administration of the hormone concentrations far above than the body's typical production may cause the body to produce less of its own natural hormone, and may also diminish sensitivity to its actions," said Dr. Adam Collins, a dietetics expert.

"Discontinuation of this hormone supplement results in hunger is unsuppressed, making overeating a significant risk."

A Lifelong Condition?

Medical guidelines recommend the injections for people with weight-linked health risks, alongside recommended lifestyle changes.

Many experts say that, due to the significant potential of relapse, the therapy should be considered life-long.

This perspective is supported by drug manufacturers, who say that the results "emphasize the persistent nature of obesity," akin to managing conditions like diabetes.

Patient Testimonies

People who have stopped the jabs explain a sudden return of appetite.

"I experienced a switch that goes on and you're instantly starving," recalled an individual.

This difficulty is compounded if patients have not established permanent dietary or behavioural changes during treatment.

Growing Use

Recent estimates show that a significant number of adults in the UK have used weight-loss jabs in the last 12 months, with desire continuing to grow.

• Use is more common among women compared to men.
• The middle-aged age group shows the greatest level of interest.
• Many access the medications through private prescriptions rather than the NHS.

In conclusion, researchers caution that while the jabs are potent agents for weight loss, they are not a permanent cure and lasting health benefits relies on ongoing lifestyle management.
