Users Coming Off Anti-Obesity Injections Regain Pounds Far More Rapidly Than Those on Conventional Diets

A recent study indicates that people who discontinue blockbuster GLP-1 drugs like Mounjaro or Wegovy can put back on shed pounds at a significantly accelerated pace than those who end conventional lifestyle regimens.

Research printed in a leading medical journal shows that while obese individuals can lose a large proportion of their total mass while using the jabs, the mass returns at an average rate of 0.8 kg per month after stopping.

"Individuals purchasing such drugs should be informed of the risk of quick rebound weight gain when the medication is stopped," cautioned lead investigator Dr. Susan Jebb.

This pace of recovery suggests a reversion to starting weight within about one and a half years.

Comparing Approaches

The research, which examined 37 of trials involving thousands of patients, compared the outcomes of these new drugs with other pills.

The team emphasize that individuals who shed pounds through dieting usually experience a slower weight regain—perhaps 0.1 kg a month—after stopping.

Explaining the Fast Regain

Experts propose the mechanism of the injections accounts for the heightened weight return.

These medications imitate a natural hormone called GLP-1, which moderates feelings of fullness.

"Long-term administration of GLP-1 levels far above than normal might result in the body to generate a reduced amount of its endogenous hormone, and may also diminish sensitivity to its effects," noted Dr. Adam Collins, a dietetics expert.

"Stopping of this hormone supplement leads to hunger is uncontrolled, making overeating a significant risk."

A Lifelong Disease?

Medical guidelines advise the injections for people with weight-linked medical conditions, alongside recommended lifestyle changes.

Professionals contend that, given the significant potential of weight regain, the treatment should be considered ongoing.

This opinion is reinforced by drug manufacturers, who say that the findings "emphasize the chronic nature of excess weight," similar to managing diseases like hypertension.

User Accounts

People who have come off the jabs report a powerful return of cravings.

"It felt as if a trigger that goes on and you become starving," recalled an individual.

This challenge is worsened if individuals have not developed sustainable dietary or behavioural modifications during treatment.

Widespread Interest

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

• Use is greater among females compared to men.
• The 40s and 50s demographic shows the highest usage rates.
• A large proportion obtain the medications through private healthcare rather than the NHS.

Ultimately, experts caution that while these medications are powerful agents for weight loss, they are not a standalone cure and lasting health benefits hinges on integrated lifestyle changes.
