Fresh analysis reveals that individuals who come off new weight-loss injections like Wegovy and Mounjaro can put back on shed pounds much more quickly than those who stop traditional lifestyle plans.
Published data in a major health publication demonstrates that while overweight individuals often shed about a fifth of their body weight while undergoing treatment, the mass is regained at an average rate of nearly a kilo each month after stopping.
"Individuals purchasing these medications need to be informed of the danger of quick rebound weight gain when the treatment concludes," stated researcher Dr. Susan Jebb.
Such speed of recovery implies a return to pre-treatment mass within about a year and a half.
Analyzing Treatments
The analysis, which looked at 37 of trials involving over 9,000 of participants, compared the effects of the injectable medications with other pills.
Scientists emphasize that individuals who shed pounds through lifestyle changes alone usually experience a less rapid creep back—perhaps 0.1 kg a month—post-intervention.
Understanding the Fast Rebound
Nutrition scientists propose the mode of action of the jabs accounts for the heightened weight return.
The injections imitate a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of the hormone levels several times higher than the body's typical production could lead to the body to produce less of its own natural hormone, and could reduce responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' means hunger is unsuppressed, making excessive eating far more likely."
A Lifelong Condition?
Medical guidelines recommend the injections for individuals with obesity-related health risks, alongside recommended diet and exercise modifications.
Professionals contend that, due to the significant potential of weight regain, the treatment is often long-term.
This view is echoed by pharmaceutical companies, who note that the findings "highlight the persistent character of obesity," similar to managing diseases like high blood pressure.
Patient Testimonies
Users who have come off the medication describe a sudden return of cravings.
"It was like a switch activating and you become starving," recalled an individual.
The struggle is compounded if patients have not established lasting lifestyle or habit modifications during treatment.
Widespread Use
Recent estimates suggest that a significant number of people in the UK have used these injections in the past year, with demand being substantial.
- Adoption is higher among women compared to men.
- The middle-aged age group shows the greatest usage rates.
- Many obtain the medications through private healthcare rather than the NHS.
Ultimately, experts stress that while GLP-1 drugs are powerful agents for weight loss, they are not a standalone solution and maintained weight loss hinges on integrated lifestyle support.
