A recent study indicates that people who discontinue blockbuster slimming jabs like semaglutide or tirzepatide can put back on reduced body mass far faster than those who halt traditional diet and exercise plans.
Research printed in a leading health publication shows that while obese individuals often shed a large proportion of their total mass while on the medication, the weight comes back at an average rate of 0.8 kg per month upon discontinuation.
"People purchasing these treatments must be cognizant of the potential of fast weight regain when the medication concludes," warns researcher Dr. Susan Jebb.
That rate of recovery suggests a reversion to starting mass within about one and a half years.
Comparing Treatments
The research, which examined 37 of trials involving thousands of patients, compared the outcomes of these new drugs with other pills.
The team point out that people who shed pounds through dieting typically see a slower weight regain—approximately 100 grams monthly—post-intervention.
Explaining the Quick Regain
Doctors suggest the mechanism of the jabs accounts for the amplified regain.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which helps regulate hunger.
"Artificially providing GLP-1 levels far above than the body's typical production could lead to the system to generate a reduced amount of its endogenous hormone, and may also diminish responsiveness to its actions," noted Dr. Adam Collins, a nutrition expert.
"Withdrawal of this medication means appetite is no longer kept in check, making binge eating much more probable."
A Lifelong Condition?
Medical guidelines advise the jabs for people with obesity-related health risks, accompanied by prescribed lifestyle changes.
A number of clinicians say that, considering the likelihood of relapse, the therapy might need to be life-long.
This opinion is supported by drug manufacturers, who note that the findings "emphasize the persistent character of excess weight," akin to managing diseases like high blood pressure.
Patient Testimonies
Users who have stopped the medication explain a sudden return of appetite.
"I experienced something flipping and you're instantly starving," described an individual.
The struggle is exacerbated if patients have not adopted permanent lifestyle or habit modifications during therapy.
Significant Interest
Figures show that millions of people in the UK have used weight-loss jabs in the past year, with demand being substantial.
- Adoption is greater among females compared to men.
- The middle-aged age group shows the highest usage rates.
- A large proportion access the medications through private healthcare rather than the NHS.
Finally, clinicians stress that while GLP-1 drugs are potent agents for shedding pounds, they are not a standalone solution and maintained weight loss relies on ongoing behavioural changes.
