A recent study indicates that individuals who come off new slimming jabs like semaglutide or tirzepatide tend to recover lost weight far faster than those who halt traditional lifestyle regimens.
Published data in a major medical journal demonstrates that while overweight people frequently drop a large proportion of their body weight while undergoing treatment, the weight returns at an average rate of nearly a kilo each month once they quit.
"Users purchasing these drugs should be cognizant of the potential of fast weight regain when the medication ends," stated expert Dr. Susan Jebb.
This pace of regain means a return to pre-treatment mass in about 18 months.
Comparing Therapies
The research, which looked at 37 of studies involving over 9,000 of patients, compared the results of the injectable medications with other pills.
The team emphasize that people who lose weight through lifestyle changes alone usually see a slower weight regain—perhaps 0.1 kg a month—post-intervention.
Explaining the Rapid Rebound
Nutrition scientists propose the mechanism of the drugs explains the heightened weight return.
GLP-1 drugs imitate a body's own chemical called GLP-1, which moderates hunger.
"Artificially providing GLP-1 levels far above than normal might result in the system to generate a reduced amount of its endogenous GLP-1, and could reduce responsiveness to its effects," noted Dr. Adam Collins, a nutrition researcher.
"Stopping of this hormone supplement results in hunger is no longer kept in check, making binge eating far more likely."
An Ongoing Disease?
Health authorities suggest the injections for individuals with weight-linked medical conditions, accompanied by recommended lifestyle changes.
Professionals argue that, given the significant potential of weight regain, the therapy might need to be life-long.
This opinion is reinforced by pharmaceutical companies, who state that the findings "underscore the persistent nature of obesity," akin to managing conditions like diabetes.
User Experiences
People who have discontinued the jabs report a powerful return of cravings.
"I experienced a trigger that goes on and you're instantly starving," recalled one woman.
This difficulty is exacerbated if patients have not developed sustainable lifestyle or habit modifications during therapy.
Widespread Use
Recent estimates show that a significant number of adults in the UK have tried these injections in the last 12 months, with interest continuing to grow.
- Adoption is more common among women than males.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion obtain the medications through private prescriptions rather than public health services.
Ultimately, researchers caution that while the jabs are effective agents for weight loss, they are not a standalone cure and maintained weight loss likely depends on combined behavioural changes.
