Users Coming Off Weight-Loss Injections Put On Pounds Four Times Faster Than People Using Diet and Exercise

A recent study indicates that patients who stop using popular GLP-1 drugs like Wegovy and Mounjaro tend to recover lost weight far faster than those who stop traditional diet and exercise regimens.

Research printed in a leading health publication demonstrates that while obese people can lose a large proportion of their body weight while undergoing treatment, the mass returns at an average rate of 0.8 kg per month after stopping.

"People using these medications must be informed of the potential of fast weight regain when the treatment is stopped," warns lead investigator Dr. Susan Jebb.

That rate of recovery means a reversion to original weight in about 18 months.

Weighing Approaches

The analysis, which examined dozens of studies involving thousands of participants, compared the effects of these new drugs with older methods.

Scientists emphasize that individuals who lose weight through dieting usually have a less rapid weight regain—around 0.1 kg a month—once they finish.

Understanding the Quick Rebound

Nutrition scientists believe the mode of action of the jabs explains the accelerated rebound.

GLP-1 drugs imitate a body's own chemical called GLP-1, which controls hunger.

"Artificially providing the hormone levels far above than the body's typical production could lead to the body to produce less of its own natural GLP-1, and could diminish sensitivity to its actions," explained Dr. Adam Collins, a dietetics expert.

"Stopping of this hormone supplement results in appetite is no longer kept in check, making excessive eating a significant risk."

A Lifelong Disease?

Medical guidelines recommend the jabs for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.

Professionals contend that, due to the likelihood of weight regain, the therapy should be considered ongoing.

This opinion is supported by drug manufacturers, who state that the results "highlight the persistent character of excess weight," akin to managing diseases like high blood pressure.

User Testimonies

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

"I experienced a trigger flipping and you're instantly extremely hungry," described an individual.

This challenge is compounded if individuals have not established lasting dietary or behavioural changes during treatment.

Growing Interest

Recent estimates suggest that millions of adults in the UK have used weight-loss jabs in the last 12 months, with desire remaining high.

• Use is greater among women compared to men.
• The middle-aged age group shows the greatest usage rates.
• Many obtain the drugs through private healthcare rather than the NHS.

Finally, clinicians stress that while the jabs are potent agents for weight loss, they are not a magic fix and lasting health benefits likely depends on integrated behavioural support.
