Users Coming Off Slimming Injections Put On Pounds Four Times Faster Than Dieters

Obesity treatment involves ongoing approaches.

New research indicates that people who stop using popular weight-loss injections like semaglutide or tirzepatide can put back on lost weight at a significantly accelerated pace than those who halt traditional lifestyle regimens.

Findings released in a leading medical journal points out that while overweight individuals can lose a large proportion of their body weight while on the medication, the weight returns at an average rate of nearly a kilo each month after stopping.

"Users purchasing these medications must be informed of the danger of quick weight regain when the therapy concludes," stated expert Dr. Susan Jebb.

Such speed of regain suggests a return to original weight within about 18 months.

Analyzing Treatments

The analysis, which reviewed 37 of studies involving over 9,000 of participants, contrasted the results of these new drugs with conventional dieting.

Scientists emphasize that individuals who lose weight through lifestyle changes alone typically experience a slower creep back—around 100 grams monthly—after stopping.

The Reason for the Quick Regain

Experts believe the mode of action of the drugs explains the amplified regain.

The injections imitate a natural hormone called GLP-1, which helps regulate feelings of fullness.

"Artificially providing the hormone concentrations far above than normal may cause the system to generate a reduced amount of its endogenous hormone, and may also diminish sensitivity to its effects," noted Dr. Adam Collins, a nutrition specialist.

"Withdrawal of this GLP-1 'fix' results in hunger is unsuppressed, making overeating much more probable."

A Lifelong Disease?

Health authorities advise the injections for individuals with obesity-related health risks, accompanied by recommended diet and exercise modifications.

Professionals say that, given the significant potential of weight regain, the therapy is often ongoing.

This view is supported by pharmaceutical companies, who state that the results "underscore the persistent nature of excess weight," akin to managing diseases like hypertension.

User Accounts

Individuals who have discontinued the jabs explain a intense return of hunger.

"I experienced a trigger flipping and you become extremely hungry," said an individual.

This difficulty is exacerbated if users have not established lasting lifestyle or habit changes during treatment.

Significant Use

Survey data suggest that a significant number of adults in the UK have tried these injections in the past year, with demand continuing to grow.

  • Use is greater among females compared to men.
  • The 40s and 50s age group shows the highest level of interest.
  • A large proportion obtain the drugs through private prescriptions rather than public health services.

Ultimately, clinicians caution that while GLP-1 drugs are potent tools for shedding pounds, they are not a magic solution and maintained weight loss hinges on integrated behavioural changes.
