New research reveals that people who discontinue new GLP-1 drugs like semaglutide or tirzepatide can put back on reduced body mass much more quickly than those who halt conventional lifestyle regimens.
Research printed in a prominent health publication shows that while obese individuals frequently drop substantial amounts of their total mass while undergoing treatment, the mass comes back at an estimated rate of nearly a kilo each month once they quit.
"Users using such medications need to be aware of the danger of rapid weight regain when the therapy concludes," cautioned expert Dr. Susan Jebb.
Such speed of regain implies a return to pre-treatment mass in about one and a half years.
Analyzing Therapies
The analysis, which looked at 37 of trials involving thousands of patients, contrasted the effects of the injectable medications with other pills.
Researchers point out that people who lose weight through diet and exercise usually see a less rapid creep back—around 100 grams monthly—post-intervention.
Explaining the Rapid Regain
Experts believe the mode of action of the drugs explains the accelerated weight return.
These medications mimic a natural hormone called glucagon-like peptide-1, which controls appetite.
"Long-term administration of the hormone levels far above than the body's typical production may cause the body to generate a reduced amount of its own natural hormone, and could lessen sensitivity to its actions," noted Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement results in hunger is no longer kept in check, making overeating a significant risk."
An Ongoing Condition?
The NHS suggest the injections for people with weight-linked health risks, accompanied by recommended diet and exercise modifications.
A number of clinicians contend that, due to the significant potential of relapse, the treatment should be considered life-long.
This view is reinforced by pharmaceutical companies, who say that the results "emphasize the persistent character of excess weight," similar to managing diseases like high blood pressure.
Patient Testimonies
Individuals who have stopped the jabs explain a intense return of cravings.
"It was like something activating and you're instantly starving," described an individual.
The struggle is worsened if patients have not adopted sustainable dietary or behavioural changes during treatment.
Growing Adoption
Survey data indicate that millions of people in the UK have used these injections in the past year, with interest being substantial.
- Adoption is greater among females than men.
- The 40s and 50s demographic shows the highest level of interest.
- Many obtain the medications through private prescriptions rather than the NHS.
Ultimately, researchers emphasize that while the jabs are potent agents for shedding pounds, they are not a magic fix and maintained weight loss relies on integrated lifestyle changes.
