New research reveals that people who stop using new weight-loss injections like Wegovy and Mounjaro may regain reduced body mass much more quickly than those who halt conventional diet and exercise programs.
Findings released in a prominent medical journal demonstrates that while overweight people often shed substantial amounts of their total mass while on the medication, the weight is regained at an estimated rate of 0.8 kg per month once they quit.
"Individuals purchasing these drugs should be informed of the risk of rapid rebound weight gain when the therapy is stopped," warns lead investigator Dr. Susan Jebb.
This pace of recovery implies a return to original mass within about 18 months.
Analyzing Approaches
The research, which reviewed 37 of trials involving thousands of participants, contrasted the effects of GLP-1 agonists with other pills.
Researchers point out that people who shed pounds through lifestyle changes alone usually experience a slower creep back—perhaps 0.1 kg a month—once they finish.
Explaining the Quick Rebound
Experts believe the way of the injections explains the accelerated weight return.
GLP-1 drugs imitate a natural hormone called GLP-1, which moderates feelings of fullness.
"Long-term administration of GLP-1 concentrations several times higher than the body's typical production might result in the body to generate a reduced amount of its endogenous hormone, and may also lessen sensitivity to its effects," noted Dr. Adam Collins, a nutrition specialist.
"Stopping of this medication means appetite is uncontrolled, making overeating much more probable."
An Ongoing Condition?
The NHS advise the injections for people with obesity-related health risks, accompanied by recommended diet and exercise modifications.
A number of clinicians say that, given the likelihood of weight regain, the therapy might need to be long-term.
This opinion is reinforced by pharmaceutical companies, who note that the results "underscore the persistent character of obesity," similar to managing diseases like high blood pressure.
Patient Testimonies
Users who have discontinued the medication report a sudden return of cravings.
"It was like something that goes on and you're instantly extremely hungry," said an individual.
This challenge is worsened if patients have not developed permanent lifestyle or habit modifications during therapy.
Significant Adoption
Recent estimates indicate that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with interest being substantial.
- Use is greater among females than males.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion obtain the drugs through private healthcare rather than public health services.
In conclusion, researchers caution that while the jabs are potent tools for weight loss, they are not a standalone fix and maintained weight loss relies on integrated behavioural management.
