Patients Coming Off Weight-Loss Jabs Put On Weight Far More Rapidly Compared to People Using Diet and Exercise

Fresh analysis suggests that patients who stop using blockbuster weight-loss injections like semaglutide or tirzepatide can put back on reduced body mass much more quickly than those who halt conventional diet and exercise plans.

Findings released in a major medical journal points out that while obese people often shed substantial amounts of their body weight while undergoing treatment, the mass returns at an estimated rate of 0.8 kg per month after stopping.

"People buying such medications need to be cognizant of the risk of quick rebound weight gain when the medication is stopped," cautioned expert Dr. Susan Jebb.

This pace of recovery suggests a reversion to pre-treatment weight within about a year and a half.

Comparing Therapies

The research, which reviewed dozens of trials involving thousands of participants, contrasted the results of these new drugs with older methods.

Researchers emphasize that people who shed pounds through diet and exercise usually see a slower creep back—perhaps 0.1 kg a month—after stopping.

The Reason for the Rapid Regain

Doctors suggest the mode of action of the jabs explains the accelerated weight return.

GLP-1 drugs mimic a body's own chemical called GLP-1, which controls feelings of fullness.

"Sustained high doses of GLP-1 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 responsiveness to its actions," explained Dr. Adam Collins, a nutrition researcher.

"Discontinuation of this hormone supplement leads to appetite is unsuppressed, making overeating much more probable."

A Chronic Issue?

Medical guidelines suggest the jabs for people with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.

Many experts contend that, considering the likelihood of weight regain, the treatment is often life-long.

This perspective is echoed by pharmaceutical companies, who note that the results "emphasize the persistent character of obesity," comparing it to managing diseases like high blood pressure.

Patient Accounts

People who have stopped the medication describe a sudden resurgence of hunger.

"It was like a switch that goes on and you become starving," said a patient.

This difficulty is worsened if individuals have not adopted lasting lifestyle or habit changes during therapy.

Widespread Interest

Figures indicate that a significant number of people in the UK have used weight-loss jabs in the past year, with demand continuing to grow.

• Adoption is higher among women than males.
• The middle-aged demographic shows the highest usage rates.
• Many obtain the medications through private prescriptions rather than the NHS.

Finally, researchers emphasize that while these medications are potent agents for weight loss, they are not a magic cure and maintained weight loss hinges on integrated lifestyle management.
