A recent study indicates that individuals who come off blockbuster weight-loss injections like Wegovy and Mounjaro may regain lost weight far faster than those who end traditional lifestyle programs.
Research printed in a prominent medical journal shows that while obese people frequently drop about a fifth of their body weight while using the jabs, the weight comes back at an average rate of 0.8 kg per month once they quit.
"Users buying these treatments should be aware of the danger of fast weight regain when the treatment ends," stated lead investigator Dr. Susan Jebb.
That rate of regain means a return to starting weight within about one and a half years.
Comparing Treatments
The analysis, which reviewed dozens of trials involving thousands of participants, compared the effects of these new drugs with conventional dieting.
Scientists emphasize that people who lose weight through lifestyle changes alone generally see a slower creep back—perhaps 100 grams monthly—once they finish.
Explaining the Quick Regain
Doctors propose the way of the injections explains the heightened rebound.
The injections copy a natural hormone called GLP-1, which controls appetite.
"Sustained high doses of GLP-1 levels several times higher than normal could lead to the system to produce less of its endogenous hormone, and could diminish sensitivity to its actions," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this medication means appetite is uncontrolled, making overeating much more probable."
A Lifelong Condition?
The NHS advise the jabs for individuals with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
Professionals argue that, due to the high risk of relapse, the therapy should be considered life-long.
This perspective is reinforced by pharmaceutical companies, who say that the findings "underscore the persistent nature of obesity," comparing it to managing diseases like diabetes.
Patient Accounts
People who have come off the jabs report a intense return of cravings.
"I experienced a trigger that goes on and you're instantly ravenous," recalled one woman.
This difficulty is exacerbated if patients have not adopted permanent lifestyle or habit modifications during treatment.
Significant Interest
Recent estimates indicate that a significant number of adults in the UK have used weight-loss jabs in the past year, with demand continuing to grow.
- Adoption is higher among women than males.
- The middle-aged demographic shows the highest usage rates.
- Many access the medications through private prescriptions rather than the NHS.
In conclusion, researchers caution that while these medications are powerful agents for weight loss, they are not a permanent solution and long-term success hinges on integrated lifestyle changes.
