Fresh analysis indicates that patients who discontinue new slimming jabs like Mounjaro or Wegovy tend to recover lost weight far faster than those who end conventional diet and exercise programs.
Findings released in a leading medical journal shows that while overweight individuals frequently drop substantial amounts of their total mass while on the medication, the weight is regained at an estimated rate of 0.8 kg per month once they quit.
"Users using these drugs must be cognizant of the danger of rapid weight regain when the treatment is stopped," cautioned researcher Dr. Susan Jebb.
This pace of recovery means a return to original mass in about a year and a half.
Comparing Therapies
The research, which looked at dozens of trials involving over 9,000 of participants, contrasted the results of GLP-1 agonists with conventional dieting.
Researchers emphasize that people who shed pounds through diet and exercise generally see a slower weight regain—perhaps 0.1 kg a month—once they finish.
Explaining the Fast Rebound
Doctors propose the mode of action of the jabs accounts for the amplified regain.
GLP-1 drugs copy a natural hormone called GLP-1, which moderates appetite.
"Artificially providing the hormone levels far above than normal may cause the body to generate a reduced amount of its endogenous hormone, and could lessen responsiveness to its effects," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement results in appetite is no longer kept in check, making binge eating a significant risk."
A Lifelong Condition?
Health authorities advise the jabs for individuals with obesity-related health risks, alongside prescribed diet and exercise modifications.
Professionals argue that, given the likelihood of weight regain, the treatment should be considered life-long.
This perspective is reinforced by pharmaceutical companies, who note that the results "highlight the chronic character of obesity," similar to managing diseases like diabetes.
Patient Testimonies
Users who have stopped the jabs describe a intense return of hunger.
"It was like something activating and I was suddenly extremely hungry," recalled a patient.
The struggle is compounded if individuals have not established permanent lifestyle or habit modifications during therapy.
Growing Adoption
Survey data suggest that a significant number of people in the UK have used these injections in the past year, with interest being substantial.
- Adoption is greater among women compared to men.
- The 40s and 50s age group shows the greatest level of interest.
- Many access the medications through private healthcare rather than public health services.
Ultimately, experts stress that while these medications are potent agents for weight loss, they are not a magic solution and maintained weight loss likely depends on ongoing behavioural support.
