New research suggests that individuals who come off blockbuster slimming jabs like Wegovy and Mounjaro may regain lost weight much more quickly than those who halt conventional diet and exercise programs.
Findings released in a leading health publication shows that while obese people can lose a large proportion of their body weight while on the medication, the mass is regained at an average rate of nearly a kilo each month after stopping.
"Individuals buying these treatments should be cognizant of the risk of rapid weight regain when the medication is stopped," warns lead investigator Dr. Susan Jebb.
This pace of recovery suggests a reversion to pre-treatment mass in about a year and a half.
Analyzing Treatments
The study, which examined dozens of studies involving over 9,000 of patients, compared the effects of these new drugs with conventional dieting.
Scientists note that individuals who shed pounds through dieting generally see a less rapid weight regain—perhaps 0.1 kg a month—after stopping.
Understanding the Fast Rebound
Nutrition scientists propose the mechanism of the jabs accounts for the accelerated regain.
These medications mimic a natural hormone called GLP-1, which controls feelings of fullness.
"Sustained high doses of the hormone concentrations several times higher than the body's typical production may cause the system to produce less of its own natural GLP-1, and may also lessen responsiveness to its actions," said Dr. Adam Collins, a nutrition expert.
"Withdrawal of this hormone supplement means appetite is uncontrolled, making overeating a significant risk."
An Ongoing Condition?
The NHS suggest the injections for individuals with weight-linked health risks, accompanied by recommended diet and exercise modifications.
A number of clinicians argue that, due to the significant potential of relapse, the therapy is often life-long.
This perspective is reinforced by pharmaceutical companies, who state that the findings "highlight the persistent character of excess weight," comparing it to managing diseases like diabetes.
Patient Testimonies
Individuals who have stopped the medication report a powerful return of cravings.
"I experienced a trigger activating and you become ravenous," said a patient.
This difficulty is worsened if users have not established permanent lifestyle or habit changes during therapy.
Widespread Use
Survey data show that millions of adults in the UK have tried these injections in the last 12 months, with desire being substantial.
- Use is more common among females compared to males.
- The middle-aged age group shows the highest level of interest.
- A large proportion access the medications through private prescriptions rather than the NHS.
In conclusion, researchers stress that while these medications are powerful tools for weight loss, they are not a magic cure and lasting health benefits likely depends on integrated lifestyle management.
