Fresh analysis reveals that individuals who discontinue popular weight-loss injections like Wegovy and Mounjaro tend to recover shed pounds far faster than those who halt conventional diet and exercise programs.
Findings released in a major health publication points out that while overweight people frequently drop about a fifth of their body weight while on the medication, the weight comes back at an estimated rate of 0.8 kg per month once they quit.
"Users buying these drugs should be cognizant of the risk of quick rebound weight gain when the medication concludes," warns expert Dr. Susan Jebb.
That rate of regain means a return to starting mass within about one and a half years.
Comparing Approaches
The analysis, which looked at dozens of trials involving thousands of participants, contrasted the results of these new drugs with conventional dieting.
Scientists emphasize that individuals who lose weight through lifestyle changes alone generally have a more gradual weight regain—around 0.1 kg a month—post-intervention.
Understanding the Rapid Regain
Doctors propose the way of the jabs accounts for the amplified weight return.
These medications copy a body's own chemical called glucagon-like peptide-1, which moderates appetite.
"Sustained high doses of GLP-1 concentrations several times higher than the body's typical production may cause the body to generate a reduced amount of its own natural hormone, and may also reduce sensitivity to its actions," said Dr. Adam Collins, a dietetics expert.
"Discontinuation of this GLP-1 'fix' results in appetite is uncontrolled, making binge eating much more probable."
A Chronic Disease?
The NHS recommend the injections for people with obesity-related health risks, accompanied by recommended lifestyle changes.
A number of clinicians contend that, given the likelihood of weight regain, the therapy might need to be life-long.
This perspective is echoed by drug manufacturers, who say that the results "highlight the persistent character of excess weight," similar to managing conditions like hypertension.
User Accounts
People who have stopped the jabs report a intense resurgence of cravings.
"I experienced a trigger flipping and you're instantly starving," described a patient.
The struggle is exacerbated if patients have not established permanent lifestyle or habit changes during treatment.
Significant Use
Survey data indicate that a significant number of people in the UK have used these injections in the past year, with interest remaining high.
- Adoption is more common among females compared to men.
- The middle-aged age group shows the greatest usage rates.
- A large proportion access the drugs through private healthcare rather than the NHS.
In conclusion, clinicians caution that while the jabs are effective tools for shedding pounds, they are not a permanent fix and maintained weight loss relies on combined lifestyle support.
