A recent study indicates that people who come off popular slimming jabs like Mounjaro or Wegovy may regain reduced body mass far faster than those who halt traditional diet and exercise regimens.
Published data in a major health publication demonstrates that while obese individuals frequently drop a large proportion of their total mass while on the medication, the weight returns at an estimated rate of nearly a kilo each month upon discontinuation.
"People buying these treatments must be cognizant of the potential of quick rebound weight gain when the therapy ends," stated researcher Dr. Susan Jebb.
That rate of regain suggests a return to original weight in about one and a half years.
Analyzing Therapies
The research, which reviewed 37 of trials involving thousands of patients, compared the results of these new drugs with conventional dieting.
Scientists emphasize that people who shed pounds through dieting generally see a more gradual weight regain—approximately 0.1 kg a month—post-intervention.
The Reason for the Rapid Rebound
Nutrition scientists believe the mechanism of the jabs explains the heightened regain.
These medications mimic a body's own chemical called GLP-1, which helps regulate hunger.
"Sustained high doses of GLP-1 levels far above than the body's typical production might result in the system to produce less of its endogenous hormone, and may also diminish responsiveness to its effects," noted Dr. Adam Collins, a dietetics expert.
"Withdrawal of this medication means appetite is no longer kept in check, making overeating a significant risk."
A Chronic Condition?
The NHS advise the injections for individuals with obesity-related health risks, alongside prescribed lifestyle changes.
Many experts argue that, due to the significant potential of weight regain, the therapy might need to be long-term.
This opinion is reinforced by drug manufacturers, who state that the results "highlight the persistent character of obesity," akin to managing diseases like hypertension.
User Experiences
People who have come off the medication describe a intense resurgence of appetite.
"It was like something activating and you become starving," described an individual.
The struggle is exacerbated if users have not established permanent dietary or behavioural changes during therapy.
Widespread Adoption
Recent estimates suggest that millions of adults in the UK have used weight-loss jabs in the last 12 months, with demand remaining high.
- Use is more common among women compared to males.
- The 40s and 50s age group shows the highest level of interest.
- A large proportion access the drugs through private prescriptions rather than public health services.
In conclusion, clinicians emphasize that while GLP-1 drugs are effective tools for shedding pounds, they are not a permanent fix and lasting health benefits relies on combined lifestyle support.
