New research indicates that people who come off new GLP-1 drugs like Wegovy and Mounjaro may regain reduced body mass at a significantly accelerated pace than those who end traditional lifestyle regimens.
Research printed in a prominent health publication shows that while overweight individuals frequently drop substantial amounts of their body weight while undergoing treatment, the weight returns at an average rate of 0.8 kg per month upon discontinuation.
"People using these treatments need to be cognizant of the danger of quick rebound weight gain when the therapy is stopped," cautioned expert Dr. Susan Jebb.
That rate of regain implies a reversion to starting weight in about a year and a half.
Weighing Treatments
The analysis, which examined 37 of studies involving thousands of patients, contrasted the effects of these new drugs with other pills.
The team point out that individuals who lose weight through dieting generally experience a less rapid weight regain—perhaps 100 grams monthly—post-intervention.
Understanding the Fast Rebound
Nutrition scientists propose the mode of action of the injections explains the heightened rebound.
The injections copy a natural hormone called glucagon-like peptide-1, which helps regulate hunger.
"Artificially providing the hormone levels several times higher than the body's typical production may cause the system to generate a reduced amount of its endogenous GLP-1, and may also reduce sensitivity to its effects," noted Dr. Adam Collins, a dietetics researcher.
"Stopping of this hormone supplement results in hunger is uncontrolled, making excessive eating far more likely."
A Lifelong Condition?
Medical guidelines advise the injections for people with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
A number of clinicians contend that, given the likelihood of relapse, the therapy might need to be ongoing.
This opinion is reinforced by pharmaceutical companies, who state that the findings "underscore the long-term character of obesity," akin to managing diseases like hypertension.
User Accounts
Users who have come off the jabs explain a sudden resurgence of appetite.
"It was like a switch activating and I was suddenly extremely hungry," recalled a patient.
The struggle is exacerbated if patients have not developed permanent lifestyle or habit changes during treatment.
Growing Use
Recent estimates indicate that a significant number of adults in the UK have used weight-loss jabs in the past year, with desire being substantial.
- Use is higher among women than males.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Ultimately, clinicians emphasize that while the jabs are powerful tools for shedding pounds, they are not a magic solution and long-term success hinges on integrated lifestyle support.
