Fresh analysis suggests that individuals who come off popular weight-loss injections like semaglutide or tirzepatide can put back on reduced body mass at a significantly accelerated pace than those who stop traditional diet and exercise programs.
Research printed in a leading health publication shows that while overweight individuals can lose about a fifth of their body weight while undergoing treatment, the weight is regained at an estimated rate of nearly a kilo each month after stopping.
"Individuals purchasing such drugs should be cognizant of the potential of quick rebound weight gain when the treatment concludes," warns expert Dr. Susan Jebb.
That rate of regain suggests a reversion to starting mass in about 18 months.
Comparing Therapies
The study, which looked at 37 of trials involving over 9,000 of patients, compared the effects of these new drugs with older methods.
Researchers note that individuals who shed pounds through lifestyle changes alone usually experience a more gradual creep back—around 100 grams monthly—once they finish.
Explaining the Fast Rebound
Doctors suggest the way of the jabs explains the amplified regain.
GLP-1 drugs imitate a body's own chemical called GLP-1, which controls appetite.
"Artificially providing the hormone concentrations far above than normal might result in the body to generate a reduced amount of its endogenous GLP-1, and may also lessen responsiveness to its actions," noted Dr. Adam Collins, a nutrition researcher.
"Stopping of this medication leads to hunger is unsuppressed, making binge eating much more probable."
A Chronic Condition?
Health authorities advise the injections for individuals with weight-linked medical conditions, accompanied by recommended lifestyle changes.
Professionals contend that, given the likelihood of weight regain, the therapy might need to be long-term.
This opinion is reinforced by drug manufacturers, who say that the findings "emphasize the persistent nature of excess weight," similar to managing diseases like hypertension.
User Experiences
People who have come off the medication describe a sudden return of appetite.
"It was like a trigger that goes on and I was suddenly extremely hungry," said an individual.
The struggle is worsened if individuals have not adopted lasting dietary or behavioural changes during therapy.
Significant Interest
Survey data indicate that millions of adults in the UK have tried these injections in the past year, with desire remaining high.
- Adoption is greater among women than males.
- The 40s and 50s demographic shows the highest usage rates.
- Many access the drugs through private prescriptions rather than the NHS.
Ultimately, experts stress that while the jabs are effective tools for weight loss, they are not a magic cure and long-term success likely depends on combined lifestyle management.
