New research indicates that people who discontinue popular slimming jabs like semaglutide or tirzepatide can put back on shed pounds at a significantly accelerated pace than those who end conventional lifestyle programs.
Published data in a prominent medical journal points out that while obese individuals frequently drop about a fifth of their total mass while undergoing treatment, the weight is regained at an average rate of 0.8 kg per month upon discontinuation.
"Individuals purchasing these medications should be cognizant of the risk of rapid rebound weight gain when the medication concludes," warns expert Dr. Susan Jebb.
Such speed of recovery suggests a reversion to starting weight within about one and a half years.
Analyzing Treatments
The analysis, which looked at dozens of trials involving thousands of participants, compared the results of the injectable medications with other pills.
Scientists emphasize that people who shed pounds through lifestyle changes alone usually see a more gradual weight regain—perhaps 0.1 kg a month—after stopping.
Explaining the Quick Regain
Nutrition scientists suggest the mechanism of the jabs accounts for the amplified weight return.
These medications mimic a body's own chemical called GLP-1, which moderates appetite.
"Sustained high doses of the hormone levels far above than normal may cause the body to generate a reduced amount of its own natural hormone, and could diminish sensitivity to its actions," said Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this hormone supplement results in hunger is no longer kept in check, making excessive eating a significant risk."
An Ongoing Condition?
The NHS recommend the injections for people with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
A number of clinicians argue that, given the significant potential of weight regain, the treatment is often ongoing.
This view is supported by drug manufacturers, who note that the results "highlight the persistent character of obesity," similar to managing diseases like high blood pressure.
Patient Experiences
Individuals who have discontinued the medication describe a powerful return of cravings.
"It was like a trigger flipping and I was suddenly ravenous," recalled a patient.
This challenge is compounded if patients have not adopted lasting dietary or behavioural changes during treatment.
Significant Adoption
Survey data suggest that a significant number of adults in the UK have tried weight-loss jabs in the last 12 months, with desire continuing to grow.
- Use is higher among females compared to men.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion access the drugs through private healthcare rather than public health services.
In conclusion, clinicians stress that while the jabs are powerful tools for shedding pounds, they are not a magic cure and long-term success likely depends on integrated lifestyle management.
