New research reveals that patients who discontinue blockbuster weight-loss injections like Mounjaro or Wegovy may regain reduced body mass much more quickly than those who halt conventional diet and exercise regimens.
Published data in a major medical journal demonstrates that while overweight individuals frequently drop a large proportion of their total mass while using the jabs, the weight returns at an estimated rate of nearly a kilo each month upon discontinuation.
"Users buying such medications must be aware of the potential of quick rebound weight gain when the medication is stopped," warns lead investigator Dr. Susan Jebb.
Such speed of regain suggests a reversion to starting weight within about one and a half years.
Analyzing Therapies
The research, which examined dozens of trials involving over 9,000 of participants, contrasted the effects of these new drugs with conventional dieting.
The team note that individuals who shed pounds through diet and exercise typically see a slower weight regain—around 0.1 kg a month—post-intervention.
Explaining the Fast Regain
Experts propose the mode of action of the jabs explains the accelerated regain.
The injections copy a natural hormone called GLP-1, which controls feelings of fullness.
"Sustained high doses of GLP-1 concentrations several times higher than normal 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.
"Discontinuation of this medication means hunger is unsuppressed, making overeating a significant risk."
A Lifelong Issue?
The NHS recommend the injections for individuals with weight-linked health risks, alongside recommended diet and exercise modifications.
Professionals say that, considering the significant potential of weight regain, the treatment might need to be long-term.
This view is reinforced by pharmaceutical companies, who say that the findings "underscore the persistent nature of excess weight," comparing it to managing conditions like high blood pressure.
User Testimonies
People who have discontinued the jabs describe a powerful resurgence of cravings.
"It felt as if a trigger activating and you're instantly starving," recalled one woman.
This difficulty is exacerbated if patients have not developed sustainable dietary or behavioural modifications during treatment.
Significant Interest
Figures show that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with desire continuing to grow.
- Adoption is more common among females compared to males.
- The middle-aged age group shows the highest usage rates.
- A large proportion access the medications through private prescriptions rather than the NHS.
In conclusion, experts stress that while the jabs are potent agents for weight loss, they are not a permanent cure and long-term success likely depends on ongoing lifestyle management.
