New research indicates that people who come off new GLP-1 drugs like Wegovy and Mounjaro tend to recover lost weight far faster than those who end traditional diet and exercise programs.
Findings released in a major health publication demonstrates that while obese individuals frequently drop a large proportion of their total mass while undergoing treatment, the mass returns at an estimated rate of nearly a kilo each month once they quit.
"Individuals using such medications need to be cognizant of the risk of fast rebound weight gain when the treatment is stopped," cautioned lead investigator Dr. Susan Jebb.
This pace of regain implies a reversion to pre-treatment weight in about a year and a half.
Analyzing Therapies
The study, which looked at dozens of trials involving thousands of participants, compared the outcomes of the injectable medications with older methods.
The team point out that people who shed pounds through dieting usually have a slower creep back—approximately 100 grams monthly—post-intervention.
Understanding the Rapid Rebound
Nutrition scientists believe the way of the jabs accounts for the accelerated weight return.
These medications imitate a body's own chemical called GLP-1, which helps regulate appetite.
"Long-term administration of the hormone concentrations several times higher than the body's typical production may cause the body to generate a reduced amount of its endogenous hormone, and may also reduce sensitivity to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this medication results in hunger is uncontrolled, making binge eating much more probable."
An Ongoing Issue?
Medical guidelines advise the jabs for people with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
Many experts say that, due to the significant potential of weight regain, the therapy is often life-long.
This perspective is supported by pharmaceutical companies, who note that the findings "emphasize the chronic nature of obesity," akin to managing diseases like high blood pressure.
User Experiences
Users who have come off the medication explain a sudden resurgence of hunger.
"It felt as if a switch that goes on and you're instantly ravenous," described a patient.
This challenge is exacerbated if individuals have not established lasting lifestyle or habit changes during therapy.
Growing Adoption
Survey data indicate that a significant number of adults in the UK have tried these injections in the last 12 months, with demand remaining high.
- Use is more common among females than men.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion access the medications through private prescriptions rather than the NHS.
In conclusion, experts emphasize that while these medications are potent tools for shedding pounds, they are not a permanent fix and long-term success hinges on ongoing behavioural management.
