Fresh analysis suggests that individuals who discontinue blockbuster slimming jabs like semaglutide or tirzepatide may regain lost weight at a significantly accelerated pace than those who halt traditional diet and exercise regimens.
Findings released in a prominent health publication points out that while obese people frequently drop substantial amounts of their body weight while on the medication, the mass comes back at an average rate of nearly a kilo each month once they quit.
"Users purchasing such treatments must be cognizant of the risk of rapid rebound weight gain when the treatment concludes," stated expert Dr. Susan Jebb.
That rate of regain implies a return to original mass in about 18 months.
Comparing Therapies
The analysis, which looked at 37 of trials involving thousands of patients, contrasted the effects of these new drugs with other pills.
Researchers emphasize that individuals who shed pounds through diet and exercise usually see a more gradual creep back—approximately 100 grams monthly—post-intervention.
Understanding the Fast Regain
Experts propose the mechanism of the injections accounts for the accelerated weight return.
GLP-1 drugs imitate a body's own chemical called GLP-1, which helps regulate hunger.
"Long-term administration of the hormone concentrations far above than normal might result in the body to generate a reduced amount of its own natural GLP-1, and could lessen sensitivity to its actions," noted Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this hormone supplement means hunger is uncontrolled, making excessive eating far more likely."
An Ongoing Disease?
Medical guidelines suggest the injections for people with obesity-related health risks, accompanied by recommended diet and exercise modifications.
Many experts contend that, considering the likelihood of relapse, the treatment should be considered ongoing.
This opinion is echoed by pharmaceutical companies, who note that the results "underscore the chronic nature of excess weight," similar to managing conditions like hypertension.
Patient Testimonies
Individuals who have come off the medication report a intense return of appetite.
"It was like a switch that goes on and you're instantly ravenous," recalled one woman.
This challenge is exacerbated if users have not established lasting dietary or behavioural modifications during treatment.
Growing Use
Figures show that millions of people in the UK have used these injections in the past year, with demand continuing to grow.
- Adoption is greater among women compared to men.
- The middle-aged age group shows the highest usage rates.
- Many access the medications through private healthcare rather than the NHS.
In conclusion, researchers emphasize that while the jabs are effective tools for weight loss, they are not a magic fix and long-term success likely depends on combined lifestyle changes.
