Fresh analysis suggests that individuals who come off popular slimming jabs like Mounjaro or Wegovy tend to recover lost weight at a significantly accelerated pace than those who halt conventional lifestyle programs.
Published data in a prominent medical journal shows that while obese people frequently drop about a fifth of their body weight while using the jabs, the weight returns at an estimated rate of nearly a kilo each month once they quit.
"Individuals purchasing these drugs need to be aware of the risk of fast rebound weight gain when the treatment is stopped," stated lead investigator Dr. Susan Jebb.
This pace of regain means a reversion to starting weight within about one and a half years.
Analyzing Therapies
The research, which looked at dozens of studies involving over 9,000 of participants, compared the results of GLP-1 agonists with conventional dieting.
Scientists emphasize that individuals who shed pounds through lifestyle changes alone typically experience a slower creep back—perhaps 100 grams monthly—once they finish.
The Reason for the Fast Regain
Experts suggest the mode of action of the jabs is key to understanding the heightened rebound.
GLP-1 drugs copy a natural hormone called GLP-1, which controls hunger.
"Sustained high doses of the hormone concentrations several times higher than the body's typical production could lead to the body to generate a reduced amount of its endogenous GLP-1, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this hormone supplement leads to appetite is uncontrolled, making overeating far more likely."
A Chronic Condition?
The NHS suggest the injections for individuals with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
Many experts contend that, considering the significant potential of relapse, the therapy is often long-term.
This opinion is reinforced by drug manufacturers, who say that the findings "underscore the chronic character of excess weight," akin to managing conditions like high blood pressure.
User Accounts
Users who have stopped the jabs explain a intense resurgence of appetite.
"I experienced something activating and you're instantly extremely hungry," said an individual.
This difficulty is exacerbated if users have not adopted sustainable dietary or behavioural modifications during treatment.
Widespread Use
Recent estimates suggest that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with interest remaining high.
- Use is more common among females compared to males.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion access the medications through private healthcare rather than the NHS.
In conclusion, experts emphasize that while these medications are potent agents for weight loss, they are not a magic fix and long-term success hinges on integrated lifestyle support.
