A recent study suggests that patients who stop using blockbuster weight-loss injections like Wegovy and Mounjaro can put back on shed pounds far faster than those who end conventional diet and exercise plans.
Research printed in a leading health publication shows that while overweight people often shed about a fifth of their total mass while using the jabs, the weight is regained at an estimated rate of 0.8 kg per month upon discontinuation.
"Users buying these medications should be cognizant of the potential of quick weight regain when the therapy is stopped," cautioned researcher Dr. Susan Jebb.
Such speed of recovery means a return to starting mass in about a year and a half.
Weighing Therapies
The study, which examined 37 of studies involving thousands of patients, contrasted the effects of these new drugs with other pills.
Researchers point out that individuals who lose weight through diet and exercise typically experience a more gradual creep back—approximately 100 grams monthly—post-intervention.
Explaining the Rapid Rebound
Experts suggest the mode of action of the jabs is key to understanding the amplified weight return.
The injections imitate a body's own chemical called GLP-1, which helps regulate appetite.
"Artificially providing the hormone concentrations several times higher than the body's typical production may cause the body to generate a reduced amount of its own natural hormone, and could diminish responsiveness to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this GLP-1 'fix' leads to appetite is unsuppressed, making excessive eating far more likely."
An Ongoing Condition?
The NHS recommend the injections for people with weight-linked medical conditions, alongside recommended diet and exercise modifications.
Professionals contend that, given the likelihood of relapse, the therapy might need to be long-term.
This perspective is echoed by drug manufacturers, who say that the findings "underscore the chronic nature of excess weight," similar to managing conditions like hypertension.
Patient Accounts
People who have come off the jabs explain a sudden return of appetite.
"It was like something flipping and you become extremely hungry," recalled one woman.
This difficulty is compounded if individuals have not established permanent lifestyle or habit changes during treatment.
Significant Use
Survey data suggest that millions of people in the UK have used these injections in the past year, with demand being substantial.
- Use is greater among women compared to males.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion obtain the medications through private healthcare rather than public health services.
In conclusion, clinicians stress that while GLP-1 drugs are effective agents for weight loss, they are not a standalone cure and long-term success relies on ongoing lifestyle management.
