Individuals Coming Off Weight-Loss Injections Gain Back Weight Far More Rapidly Compared to Dieters

A recent study reveals that patients who come off new GLP-1 drugs like Wegovy and Mounjaro can put back on lost weight far faster than those who end conventional lifestyle regimens.

Findings released in a major health publication shows that while obese individuals often shed substantial amounts of their body weight while undergoing treatment, the weight returns at an average rate of 0.8 kg per month after stopping.

"People using such medications need to be cognizant of the danger of quick weight regain when the therapy concludes," stated researcher Dr. Susan Jebb.

Such speed of regain means a reversion to starting weight within about one and a half years.

Comparing Therapies

The analysis, which reviewed dozens of trials involving thousands of participants, compared the effects of these new drugs with conventional dieting.

The team point out that individuals who lose weight through diet and exercise usually have a less rapid weight regain—perhaps 100 grams monthly—post-intervention.

The Reason for the Rapid Rebound

Experts propose the mode of action of the jabs explains the accelerated weight return.

These medications copy a body's own chemical called GLP-1, which controls hunger.

"Sustained high doses of the hormone concentrations several times higher than normal might result in the body to produce less of its own natural hormone, and may also diminish sensitivity to its effects," noted Dr. Adam Collins, a dietetics expert.

"Stopping of this GLP-1 'fix' means hunger is uncontrolled, making excessive eating a significant risk."

An Ongoing Disease?

Medical guidelines suggest the jabs for people with weight-linked health risks, alongside recommended diet and exercise modifications.

Professionals contend that, due to the significant potential of weight regain, the treatment is often ongoing.

This perspective is reinforced by drug manufacturers, who state that the results "underscore the persistent character of obesity," comparing it to managing diseases like diabetes.

User Experiences

People who have come off the medication explain a sudden resurgence of hunger.

"I experienced a trigger flipping and I was suddenly starving," recalled an individual.

The struggle is worsened if patients have not adopted sustainable dietary or behavioural modifications during therapy.

Widespread Interest

Survey data indicate that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with desire being substantial.

• Use is greater among females compared to men.
• The 40s and 50s age group shows the highest usage rates.
• Many obtain the medications through private prescriptions rather than the NHS.

Ultimately, experts stress that while these medications are powerful tools for weight loss, they are not a permanent fix and maintained weight loss likely depends on integrated lifestyle management.
