Fresh analysis reveals that individuals who come off blockbuster weight-loss injections like Mounjaro or Wegovy tend to recover shed pounds far faster than those who halt conventional diet and exercise plans.
Research printed in a leading medical journal demonstrates that while obese people frequently drop about a fifth of their body weight while on the medication, the mass returns at an estimated rate of 0.8 kg per month once they quit.
"Individuals using such treatments should be aware of the danger of quick weight regain when the therapy concludes," cautioned expert Dr. Susan Jebb.
That rate of recovery implies a return to pre-treatment mass within about one and a half years.
Weighing Approaches
The study, which examined 37 of studies involving thousands of participants, compared the outcomes of these new drugs with conventional dieting.
Scientists point out that people who shed pounds through lifestyle changes alone generally have a slower weight regain—perhaps 0.1 kg a month—after stopping.
Explaining the Quick Rebound
Doctors suggest the way of the drugs accounts for the amplified regain.
These medications mimic a natural hormone called glucagon-like peptide-1, which controls appetite.
"Artificially providing GLP-1 levels several times higher than normal might result in the system to produce less of its endogenous GLP-1, and could diminish sensitivity to its effects," said Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this hormone supplement leads to hunger is unsuppressed, making excessive eating much more probable."
A Chronic Condition?
The NHS advise the injections for people with obesity-related health risks, accompanied by prescribed diet and exercise modifications.
Professionals contend that, considering the significant potential of weight regain, the treatment should be considered ongoing.
This perspective is supported by drug manufacturers, who state that the findings "highlight the chronic character of excess weight," similar to managing conditions like hypertension.
Patient Experiences
Users who have discontinued the jabs report a intense resurgence of hunger.
"It was like a switch that goes on and you become extremely hungry," said one woman.
This challenge is exacerbated if patients have not established sustainable dietary or behavioural modifications during therapy.
Significant Adoption
Recent estimates suggest that a significant number of adults in the UK have tried weight-loss jabs in the past year, with interest continuing to grow.
- Use is more common among females compared to males.
- The middle-aged age group shows the greatest level of interest.
- Many obtain the medications through private prescriptions rather than the NHS.
In conclusion, experts emphasize that while these medications are effective tools for weight loss, they are not a magic solution and lasting health benefits hinges on combined behavioural changes.
