New research indicates that individuals who come off blockbuster weight-loss injections like Wegovy and Mounjaro can put back on lost weight far faster than those who stop conventional diet and exercise regimens.
Published data in a major health publication demonstrates that while overweight people often shed a large proportion of their total mass while on the medication, the mass returns at an estimated rate of nearly a kilo each month upon discontinuation.
"People buying these drugs should be aware of the potential of quick weight regain when the therapy concludes," cautioned lead investigator Dr. Susan Jebb.
This pace of regain implies a reversion to starting weight within about a year and a half.
Analyzing Approaches
The research, which examined dozens of studies involving over 9,000 of participants, contrasted the outcomes of the injectable medications with other pills.
Researchers point out that people who shed pounds through lifestyle changes alone typically experience a slower weight regain—around 0.1 kg a month—after stopping.
Understanding the Fast Regain
Experts believe the way of the drugs is key to understanding the heightened rebound.
These medications imitate a natural hormone called GLP-1, which helps regulate appetite.
"Artificially providing GLP-1 levels far above than the body's typical production could lead to the system to generate a reduced amount of its own natural hormone, and could lessen responsiveness to its actions," said Dr. Adam Collins, a nutrition expert.
"Discontinuation of this hormone supplement means hunger is unsuppressed, making excessive eating a significant risk."
An Ongoing Disease?
Medical guidelines advise the injections for individuals with obesity-related medical conditions, alongside recommended diet and exercise modifications.
Professionals contend that, considering the likelihood of weight regain, the treatment is often life-long.
This view is supported by pharmaceutical companies, who say that the findings "emphasize the persistent nature of excess weight," similar to managing conditions like hypertension.
Patient Accounts
Individuals who have discontinued the jabs explain a intense resurgence of appetite.
"I experienced a switch activating and you become ravenous," said one woman.
This difficulty is worsened if patients have not adopted sustainable dietary or behavioural changes during therapy.
Significant Interest
Survey data suggest that millions of adults in the UK have used these injections in the past year, with interest being substantial.
- Adoption is greater among women than males.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion obtain the medications through private healthcare rather than public health services.
Finally, experts stress that while GLP-1 drugs are effective agents for weight loss, they are not a magic fix and maintained weight loss relies on combined lifestyle changes.
