Fresh analysis indicates that individuals who come off blockbuster slimming jabs like Wegovy and Mounjaro may regain lost weight far faster than those who halt conventional diet and exercise programs.
Findings released in a major health publication demonstrates that while obese people often shed substantial amounts of their body weight while undergoing treatment, the weight is regained at an average rate of nearly a kilo each month upon discontinuation.
"Users using such drugs need to be cognizant of the potential of rapid rebound weight gain when the treatment ends," cautioned expert Dr. Susan Jebb.
That rate of recovery implies a return to starting weight within about 18 months.
Comparing Therapies
The analysis, which looked at 37 of studies involving thousands of patients, contrasted the outcomes of the injectable medications with conventional dieting.
The team point out that people who shed pounds through diet and exercise usually experience a slower creep back—approximately 100 grams monthly—once they finish.
Understanding the Rapid Regain
Doctors believe the way of the drugs accounts for the heightened regain.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.
"Artificially providing the hormone concentrations far above than the body's typical production may cause the system to generate a reduced amount of its endogenous GLP-1, and may also lessen responsiveness to its actions," said Dr. Adam Collins, a dietetics expert.
"Stopping of this medication results in hunger is no longer kept in check, making overeating much more probable."
A Chronic Condition?
The NHS recommend the injections for people with weight-linked medical conditions, accompanied by recommended lifestyle changes.
A number of clinicians contend that, due to the high risk of weight regain, the treatment should be considered long-term.
This opinion is reinforced by drug manufacturers, who state that the findings "highlight the chronic character of excess weight," akin to managing diseases like hypertension.
Patient Testimonies
People who have come off the jabs report a intense return of hunger.
"I experienced something that goes on and you become extremely hungry," said an individual.
This difficulty is worsened if patients have not developed lasting lifestyle or habit changes during therapy.
Significant Use
Recent estimates suggest that a significant number of adults in the UK have used these injections in the past year, with demand being substantial.
- Use is greater among females compared to males.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion access the drugs through private healthcare rather than public health services.
Ultimately, researchers emphasize that while these medications are potent tools for weight loss, they are not a magic solution and maintained weight loss likely depends on combined lifestyle support.
