Fresh analysis reveals that people who come off new GLP-1 drugs like semaglutide or tirzepatide may regain reduced body mass far faster than those who stop conventional lifestyle programs.
Research printed in a leading health publication shows that while obese individuals often shed a large proportion of their body weight while undergoing treatment, the mass comes back at an average rate of 0.8 kg per month upon discontinuation.
"People buying these drugs should be aware of the risk of rapid rebound weight gain when the medication ends," warns expert Dr. Susan Jebb.
That rate of recovery implies a reversion to original weight in about one and a half years.
Analyzing Therapies
The study, which examined dozens of studies involving over 9,000 of participants, compared the results of these new drugs with conventional dieting.
The team emphasize that individuals who lose weight through diet and exercise generally have a more gradual weight regain—perhaps 100 grams monthly—post-intervention.
Understanding the Fast Regain
Experts propose the way of the jabs accounts for the accelerated rebound.
These medications imitate a body's own chemical called GLP-1, which moderates hunger.
"Artificially providing GLP-1 levels far above than normal could lead to the body to generate a reduced amount of its endogenous GLP-1, and could lessen sensitivity to its actions," said Dr. Adam Collins, a nutrition expert.
"Stopping of this medication leads to appetite is uncontrolled, making excessive eating far more likely."
A Lifelong Condition?
Health authorities advise the injections for people with weight-linked health risks, alongside recommended lifestyle changes.
Many experts say that, considering the significant potential of relapse, the therapy should be considered life-long.
This opinion is reinforced by pharmaceutical companies, who say that the findings "highlight the persistent nature of excess weight," similar to managing conditions like diabetes.
User Testimonies
Users who have come off the jabs report a sudden return of hunger.
"It was like something flipping and you're instantly starving," described a patient.
This challenge is exacerbated if individuals have not adopted permanent lifestyle or habit modifications during therapy.
Widespread Adoption
Survey data show that a significant number of people in the UK have tried weight-loss jabs in the past year, with demand continuing to grow.
- Use is greater among females than men.
- The middle-aged age group shows the greatest usage rates.
- Many obtain the drugs through private healthcare rather than the NHS.
Ultimately, experts caution that while these medications are potent tools for shedding pounds, they are not a magic solution and maintained weight loss hinges on ongoing lifestyle support.
