Individuals Discontinuing Slimming Medications Regain Pounds Far More Rapidly Compared to People Using Diet and Exercise

A recent study reveals that people who come off blockbuster GLP-1 drugs like Wegovy and Mounjaro can put back on reduced body mass much more quickly than those who end conventional lifestyle regimens.

Findings released in a leading health publication points out that while obese individuals frequently drop substantial amounts of their total mass while using the jabs, the mass returns at an average rate of 0.8 kg per month upon discontinuation.

"Individuals purchasing these drugs must be cognizant of the danger of quick rebound weight gain when the therapy ends," warns researcher Dr. Susan Jebb.

That rate of regain implies a reversion to original weight in about 18 months.

Analyzing Treatments

The study, which looked at dozens of trials involving over 9,000 of participants, compared the effects of GLP-1 agonists with other pills.

Scientists note that people who lose weight through diet and exercise usually have a slower weight regain—perhaps 100 grams monthly—after stopping.

Explaining the Rapid Rebound

Nutrition scientists believe the mode of action of the injections accounts for the heightened weight return.

The injections copy a natural hormone called glucagon-like peptide-1, which helps regulate appetite.

"Sustained high doses of GLP-1 concentrations far above than normal might result in the body to generate a reduced amount of its own natural hormone, and could lessen responsiveness to its actions," said Dr. Adam Collins, a dietetics researcher.

"Withdrawal of this medication means hunger is unsuppressed, making binge eating far more likely."

A Chronic Issue?

The NHS recommend the jabs for individuals with weight-linked medical conditions, alongside recommended lifestyle changes.

Many experts argue that, given the significant potential of relapse, the treatment should be considered life-long.

This opinion is supported by pharmaceutical companies, who say that the findings "emphasize the chronic nature of excess weight," comparing it to managing conditions like diabetes.

Patient Experiences

Individuals who have stopped the medication describe a intense return of hunger.

"It was like a switch activating and you're instantly starving," recalled an individual.

The struggle is exacerbated if users have not adopted permanent lifestyle or habit modifications during therapy.

Growing Interest

Figures indicate that millions of people in the UK have used these injections in the past year, with desire continuing to grow.

• Use is greater among women than men.
• The middle-aged age group shows the highest level of interest.
• A large proportion obtain the medications through private prescriptions rather than public health services.

Finally, researchers stress that while these medications are effective agents for weight loss, they are not a magic fix and lasting health benefits relies on combined behavioural management.
