Individuals Stopping Weight-Loss Medications Put On Weight Far More Rapidly Compared to People Using Diet and Exercise

New research reveals that patients who stop using new weight-loss injections like Wegovy and Mounjaro tend to recover lost weight at a significantly accelerated pace than those who stop conventional diet and exercise programs.

Published data in a prominent medical journal shows that while overweight people often shed substantial amounts of their body weight while undergoing treatment, the weight returns at an estimated rate of 0.8 kg per month after stopping.

"People purchasing these treatments need to be informed of the danger of quick rebound weight gain when the medication concludes," warns researcher Dr. Susan Jebb.

Such speed of regain implies a reversion to starting mass within about one and a half years.

Analyzing Therapies

The study, which reviewed dozens of studies involving over 9,000 of patients, compared the results of GLP-1 agonists with older methods.

Scientists emphasize that individuals who shed pounds through diet and exercise generally see a slower weight regain—approximately 100 grams monthly—once they finish.

Explaining the Rapid Rebound

Nutrition scientists propose the mode of action of the jabs explains the accelerated regain.

These medications copy a natural hormone called GLP-1, which controls feelings of fullness.

"Long-term administration of GLP-1 concentrations several times higher than the body's typical production might result in the system to produce less of its own natural hormone, and could lessen responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.

"Withdrawal of this hormone supplement results in appetite is no longer kept in check, making excessive eating much more probable."

A Chronic Issue?

The NHS advise the jabs for people with weight-linked medical conditions, alongside prescribed lifestyle changes.

Professionals contend that, considering the high risk of weight regain, the treatment should be considered long-term.

This view is reinforced by drug manufacturers, who note that the results "emphasize the chronic nature of excess weight," akin to managing conditions like hypertension.

Patient Accounts

Users who have discontinued the jabs explain a powerful return of hunger.

"I experienced a switch that goes on and you become starving," described a patient.

The struggle is exacerbated if patients have not established sustainable dietary or behavioural modifications during treatment.

Widespread Use

Figures suggest that millions of adults in the UK have used weight-loss jabs in the past year, with desire being substantial.

• Adoption is higher among women compared to men.
• The 40s and 50s age group shows the highest level of interest.
• A large proportion access the medications through private prescriptions rather than public health services.

In conclusion, researchers stress that while GLP-1 drugs are effective tools for shedding pounds, they are not a magic fix and long-term success relies on ongoing behavioural changes.
