New research indicates that patients who stop using popular weight-loss injections like Wegovy and Mounjaro may regain lost weight far faster than those who halt traditional diet and exercise plans.
Findings released in a major health publication demonstrates that while obese people frequently drop about a fifth of their total mass while using the jabs, the weight is regained at an estimated rate of nearly a kilo each month after stopping.
"Users buying such drugs should be informed of the potential of fast weight regain when the treatment ends," warns researcher Dr. Susan Jebb.
This pace of recovery suggests a reversion to pre-treatment mass in about one and a half years.
Analyzing Approaches
The study, which looked at dozens of studies involving thousands of participants, compared the effects of GLP-1 agonists with conventional dieting.
Scientists point out that individuals who lose weight through lifestyle changes alone typically experience a more gradual creep back—around 0.1 kg a month—once they finish.
The Reason for the Rapid Rebound
Experts suggest the mode of action of the injections explains the amplified rebound.
These medications imitate a natural hormone called glucagon-like peptide-1, which controls appetite.
"Sustained high doses of the hormone concentrations several times higher than normal could lead to the body to produce less of its endogenous GLP-1, and could reduce responsiveness to its effects," noted Dr. Adam Collins, a dietetics specialist.
"Stopping of this hormone supplement means hunger is uncontrolled, making excessive eating a significant risk."
An Ongoing Issue?
Medical guidelines recommend the jabs for people with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
Many experts say that, given the high risk of relapse, the treatment is often long-term.
This view is echoed by drug manufacturers, who say that the results "underscore the long-term character of obesity," similar to managing conditions like hypertension.
User Testimonies
Individuals who have discontinued the jabs explain a powerful return of appetite.
"It felt as if a trigger that goes on and I was suddenly extremely hungry," said a patient.
This difficulty is worsened if users have not adopted permanent lifestyle or habit modifications during treatment.
Significant Interest
Survey data indicate that a significant number of adults in the UK have tried weight-loss jabs in the last 12 months, with desire being substantial.
- Adoption is higher among women compared to males.
- The middle-aged age group shows the highest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
In conclusion, clinicians caution that while these medications are potent tools for shedding pounds, they are not a permanent solution and lasting health benefits relies on integrated behavioural changes.
