A recent study reveals that individuals who come off blockbuster weight-loss injections like Wegovy and Mounjaro may regain shed pounds far faster than those who stop traditional lifestyle programs.
Findings released in a leading medical journal demonstrates that while obese people can lose substantial amounts of their body weight while on the medication, the mass comes back at an average rate of nearly a kilo each month upon discontinuation.
"Users using these medications should be informed of the potential of rapid rebound weight gain when the treatment ends," warns expert Dr. Susan Jebb.
This pace of regain means a reversion to starting mass in about 18 months.
Weighing Therapies
The study, which looked at dozens of studies involving thousands of participants, contrasted the results of these new drugs with older methods.
The team point out that individuals who shed pounds through dieting generally experience a more gradual weight regain—around 0.1 kg a month—after stopping.
The Reason for the Quick Regain
Experts believe the mode of action of the drugs accounts for the accelerated weight return.
The injections copy a body's own chemical called glucagon-like peptide-1, which helps regulate hunger.
"Artificially providing the hormone concentrations far above than normal may cause the body to produce less of its endogenous hormone, and could reduce sensitivity to its effects," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this GLP-1 'fix' means appetite is no longer kept in check, making binge eating a significant risk."
A Chronic Disease?
Medical guidelines recommend the jabs for people with weight-linked medical conditions, alongside recommended diet and exercise modifications.
Professionals say that, due to the likelihood of weight regain, the treatment is often ongoing.
This perspective is reinforced by drug manufacturers, who note that the findings "underscore the persistent character of excess weight," similar to managing diseases like high blood pressure.
Patient Experiences
Users who have stopped the medication describe a intense resurgence of cravings.
"It was like something flipping and you become ravenous," described one woman.
This challenge is exacerbated if individuals have not adopted sustainable lifestyle or habit modifications during therapy.
Growing Interest
Survey data suggest that a significant number of people in the UK have tried these injections in the last 12 months, with demand remaining high.
- Use is higher among women than males.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion access the medications through private healthcare rather than public health services.
In conclusion, researchers emphasize that while GLP-1 drugs are effective agents for shedding pounds, they are not a magic solution and maintained weight loss likely depends on integrated lifestyle support.
