New research indicates that individuals who discontinue blockbuster weight-loss injections like Wegovy and Mounjaro tend to recover shed pounds much more quickly than those who halt conventional lifestyle programs.
Research printed in a leading medical journal points out that while obese individuals often shed a large proportion of their body weight while undergoing treatment, the mass returns at an average rate of 0.8 kg per month after stopping.
"Individuals using such treatments must be cognizant of the danger of quick weight regain when the medication concludes," cautioned expert Dr. Susan Jebb.
This pace of recovery suggests a return to pre-treatment mass in about one and a half years.
Analyzing Therapies
The study, which looked at dozens of studies involving over 9,000 of patients, compared the outcomes of these new drugs with older methods.
Scientists point out that people who shed pounds through lifestyle changes alone typically experience a more gradual weight regain—approximately 100 grams monthly—post-intervention.
Explaining the Rapid Regain
Nutrition scientists propose the mode of action of the jabs explains the heightened regain.
GLP-1 drugs mimic a natural hormone called glucagon-like peptide-1, which moderates feelings of fullness.
"Sustained high doses of GLP-1 levels far above than normal might result in the body to generate a reduced amount of its own natural GLP-1, and could diminish responsiveness to its effects," noted Dr. Adam Collins, a nutrition specialist.
"Stopping of this GLP-1 'fix' means appetite is no longer kept in check, making overeating much more probable."
A Chronic Condition?
Medical guidelines suggest the injections for people with obesity-related health risks, alongside prescribed diet and exercise modifications.
A number of clinicians argue that, considering the likelihood of weight regain, the treatment is often life-long.
This opinion is reinforced by drug manufacturers, who note that the findings "emphasize the persistent character of excess weight," similar to managing conditions like diabetes.
Patient Accounts
People who have come off the medication explain a intense return of cravings.
"I experienced something that goes on and I was suddenly starving," recalled one woman.
This difficulty is exacerbated if individuals have not developed sustainable dietary or behavioural changes during treatment.
Growing Adoption
Figures indicate that a significant number of people in the UK have used these injections in the past year, with demand being substantial.
- Use is greater among females compared to men.
- The middle-aged age group shows the greatest level of interest.
- Many obtain the drugs through private healthcare rather than the NHS.
In conclusion, researchers stress that while GLP-1 drugs are effective agents for shedding pounds, they are not a standalone fix and maintained weight loss likely depends on combined lifestyle support.
