Fresh analysis reveals that people who stop using blockbuster slimming jabs like Mounjaro or Wegovy may regain lost weight at a significantly accelerated pace than those who end traditional diet and exercise plans.
Findings released in a major medical journal shows that while obese people often shed a large proportion of their total mass while undergoing treatment, the mass is regained at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals buying these treatments must be aware of the danger of fast rebound weight gain when the treatment is stopped," cautioned expert Dr. Susan Jebb.
That rate of regain means a reversion to starting mass within about one and a half years.
Analyzing Approaches
The analysis, which looked at dozens of trials involving thousands of patients, contrasted the outcomes of the injectable medications with conventional dieting.
The team point out that individuals who lose weight through dieting typically experience a more gradual creep back—approximately 0.1 kg a month—post-intervention.
Understanding the Fast Rebound
Experts propose the mechanism of the drugs accounts for the amplified regain.
The injections copy a natural hormone called glucagon-like peptide-1, which controls appetite.
"Artificially providing GLP-1 levels far above than normal could lead to the body to generate a reduced amount of its own natural GLP-1, and may also lessen sensitivity to its effects," explained Dr. Adam Collins, a nutrition expert.
"Withdrawal of this medication results in hunger is uncontrolled, making overeating a significant risk."
An Ongoing Condition?
Health authorities advise the jabs for individuals with weight-linked medical conditions, alongside prescribed lifestyle changes.
Professionals say that, given the significant potential of weight regain, the therapy should be considered long-term.
This view is supported by drug manufacturers, who note that the findings "emphasize the chronic character of obesity," akin to managing diseases like hypertension.
User Testimonies
Individuals who have come off the jabs report a intense resurgence of hunger.
"It felt as if something flipping and you become starving," recalled one woman.
The struggle is exacerbated if patients have not developed lasting lifestyle or habit changes during therapy.
Growing Adoption
Figures suggest that a significant number of people in the UK have tried these injections in the past year, with desire being substantial.
- Adoption is higher among women than men.
- The 40s and 50s age group shows the highest usage rates.
- Many access the drugs through private healthcare rather than the NHS.
Ultimately, experts stress that while these medications are potent agents for weight loss, they are not a standalone cure and long-term success likely depends on combined behavioural support.
