New research indicates that individuals who come off blockbuster weight-loss injections like Mounjaro or Wegovy can put back on reduced body mass far faster than those who halt conventional diet and exercise programs.
Research printed in a prominent medical journal points out that while obese people can lose substantial amounts of their total mass while undergoing treatment, the mass returns at an estimated rate of nearly a kilo each month after stopping.
"Users using such medications should be aware of the potential of fast weight regain when the medication concludes," cautioned expert Dr. Susan Jebb.
Such speed of recovery suggests a return to original weight within about a year and a half.
Weighing Approaches
The analysis, which examined 37 of studies involving over 9,000 of participants, contrasted the effects of the injectable medications with conventional dieting.
The team emphasize that individuals who shed pounds through lifestyle changes alone typically experience a slower weight regain—approximately 100 grams monthly—post-intervention.
Understanding the Rapid Regain
Experts propose the way of the drugs explains the heightened weight return.
GLP-1 drugs imitate a natural hormone called GLP-1, which moderates appetite.
"Artificially providing GLP-1 concentrations several times higher than normal may cause the system to produce less of its own natural hormone, and may also lessen responsiveness to its effects," noted Dr. Adam Collins, a dietetics researcher.
"Stopping of this GLP-1 'fix' results in appetite is unsuppressed, making excessive eating a significant risk."
A Chronic Disease?
The NHS advise the injections for people with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
A number of clinicians say that, given the likelihood of relapse, the therapy might need to be ongoing.
This view is reinforced by drug manufacturers, who say that the results "underscore the long-term character of excess weight," similar to managing diseases like diabetes.
Patient Testimonies
Individuals who have come off the medication describe a intense resurgence of cravings.
"It felt as if a switch flipping and I was suddenly starving," described an individual.
The struggle is compounded if users have not developed permanent dietary or behavioural modifications during treatment.
Growing Interest
Survey data suggest that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with demand remaining high.
- Use is greater among females compared to males.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion obtain the drugs through private healthcare rather than public health services.
In conclusion, clinicians stress that while the jabs are effective agents for shedding pounds, they are not a standalone fix and maintained weight loss relies on combined lifestyle support.
