New research indicates that individuals who stop using new weight-loss injections like Wegovy and Mounjaro can put back on lost weight much more quickly than those who halt traditional diet and exercise plans.
Findings released in a prominent health publication shows that while overweight people frequently drop about a fifth of their total mass while using the jabs, the mass is regained at an average rate of 0.8 kg per month upon discontinuation.
"Users buying these treatments need to be informed of the risk of rapid weight regain when the treatment is stopped," cautioned researcher Dr. Susan Jebb.
Such speed of recovery suggests a reversion to starting mass within about 18 months.
Analyzing Approaches
The analysis, which examined dozens of trials involving thousands of patients, compared the results of GLP-1 agonists with older methods.
The team note that individuals who shed pounds through lifestyle changes alone usually experience a more gradual creep back—around 0.1 kg a month—post-intervention.
Explaining the Quick Regain
Doctors propose the way of the injections explains the accelerated weight return.
The injections copy a natural hormone called GLP-1, which moderates hunger.
"Sustained high doses of the hormone levels far above than the body's typical production might result in the body to produce less of its own natural GLP-1, and may also diminish sensitivity to its effects," noted Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this GLP-1 'fix' leads to appetite is unsuppressed, making binge eating much more probable."
A Lifelong Disease?
Health authorities recommend the injections for people with weight-linked medical conditions, accompanied by recommended lifestyle changes.
Many experts argue that, due to the significant potential of weight regain, the therapy should be considered life-long.
This perspective is echoed by pharmaceutical companies, who say that the findings "highlight the persistent character of obesity," akin to managing diseases like high blood pressure.
User Accounts
Individuals who have come off the jabs report a powerful resurgence of cravings.
"I experienced a trigger that goes on and I was suddenly ravenous," recalled a patient.
The struggle is compounded if patients have not established sustainable lifestyle or habit changes during treatment.
Widespread Adoption
Figures show that millions of adults in the UK have tried these injections in the last 12 months, with interest continuing to grow.
- Use is greater among women than males.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the medications through private healthcare rather than the NHS.
Ultimately, experts stress that while GLP-1 drugs are effective tools for weight loss, they are not a magic solution and long-term success likely depends on integrated lifestyle management.
