Fresh analysis reveals that patients who stop using new weight-loss injections like Wegovy and Mounjaro tend to recover shed pounds far faster than those who stop conventional lifestyle plans.
Findings released in a major medical journal demonstrates that while obese people can lose about a fifth of their total mass while undergoing treatment, the mass comes back at an average rate of 0.8 kg per month after stopping.
"Individuals buying these drugs must be cognizant of the danger of fast weight regain when the treatment ends," warns expert Dr. Susan Jebb.
That rate of regain means a reversion to original weight in about one and a half years.
Weighing Approaches
The analysis, which reviewed 37 of studies involving over 9,000 of patients, contrasted the outcomes of the injectable medications with older methods.
Researchers note that individuals who lose weight through dieting usually experience a less rapid weight regain—perhaps 100 grams monthly—after stopping.
Understanding the Rapid Rebound
Nutrition scientists propose the way of the injections accounts for the accelerated weight return.
These medications imitate a natural hormone called GLP-1, which controls feelings of fullness.
"Long-term administration of GLP-1 levels far above than the body's typical production might result in the body to generate a reduced amount of its endogenous hormone, and may also diminish responsiveness to its effects," explained Dr. Adam Collins, a nutrition expert.
"Discontinuation of this hormone supplement results in appetite is no longer kept in check, making binge eating far more likely."
A Chronic Disease?
The NHS suggest the jabs for people with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
Professionals contend that, given the high risk of weight regain, the therapy is often ongoing.
This perspective is supported by pharmaceutical companies, who state that the findings "underscore the long-term nature of excess weight," similar to managing diseases like high blood pressure.
Patient Accounts
Individuals who have stopped the medication describe a powerful return of appetite.
"It was like a trigger flipping and you're instantly starving," recalled one woman.
The struggle is worsened if users have not adopted permanent dietary or behavioural changes during therapy.
Growing Use
Figures indicate that millions of people in the UK have used weight-loss jabs in the past year, with interest remaining high.
- Adoption is greater among women than men.
- The 40s and 50s demographic shows the highest usage rates.
- Many access the drugs through private healthcare rather than the NHS.
In conclusion, experts stress that while these medications are effective agents for weight loss, they are not a permanent fix and maintained weight loss relies on ongoing behavioural management.
