Users Coming Off Slimming Medications Gain Back Pounds Far More Rapidly Than Dieters

New research suggests that patients who stop using popular GLP-1 drugs like semaglutide or tirzepatide may regain reduced body mass far faster than those who halt conventional diet and exercise programs.

Findings released in a leading health publication points out that while obese people often shed about a fifth of their body weight while using the jabs, the weight is regained at an estimated rate of nearly a kilo each month after stopping.

"People purchasing such drugs must be cognizant of the risk of rapid rebound weight gain when the treatment concludes," cautioned researcher Dr. Susan Jebb.

Such speed of regain suggests a reversion to pre-treatment weight in about one and a half years.

Weighing Treatments

The study, which reviewed 37 of trials involving thousands of participants, compared the results of GLP-1 agonists with older methods.

Scientists point out that individuals who shed pounds through diet and exercise generally experience a more gradual weight regain—around 0.1 kg a month—after stopping.

Understanding the Quick Regain

Nutrition scientists suggest the way of the injections explains the accelerated rebound.

These medications mimic a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.

"Sustained high doses of the hormone levels several times higher than normal could lead to the body to produce less of its own natural GLP-1, and could diminish responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.

"Stopping of this hormone supplement leads to hunger is no longer kept in check, making overeating far more likely."

A Lifelong Condition?

Medical guidelines suggest the jabs for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.

A number of clinicians argue that, considering the likelihood of relapse, the therapy is often ongoing.

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

User Accounts

Users who have discontinued the jabs explain a powerful resurgence of cravings.

"It was like something that goes on and you're instantly starving," said one woman.

This difficulty is exacerbated if users have not developed lasting dietary or behavioural modifications during therapy.

Widespread Use

Figures indicate that millions of people in the UK have used these injections in the last 12 months, with demand remaining high.

• Adoption is more common among females than men.
• The middle-aged age group shows the greatest usage rates.
• Many access the medications through private prescriptions rather than the NHS.

Ultimately, clinicians stress that while the jabs are powerful agents for shedding pounds, they are not a magic solution and lasting health benefits relies on ongoing lifestyle support.
