New research reveals that patients who discontinue new weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds at a significantly accelerated pace than those who end traditional diet and exercise plans.
Findings released in a major medical journal points out that while obese people frequently drop substantial amounts of their total mass while using the jabs, the mass is regained at an average rate of 0.8 kg per month once they quit.
"Individuals buying these drugs need to be aware of the risk of rapid weight regain when the medication concludes," warns expert Dr. Susan Jebb.
That rate of recovery suggests a reversion to pre-treatment mass in about a year and a half.
Weighing Approaches
The analysis, which examined dozens of studies involving thousands of participants, compared the results of GLP-1 agonists with other pills.
The team note that people who shed pounds through dieting generally see a slower creep back—approximately 0.1 kg a month—post-intervention.
Explaining the Fast Rebound
Experts suggest the way of the jabs accounts for the amplified weight return.
These medications imitate a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 levels far above than the body's typical production may cause the body to generate a reduced amount of its endogenous hormone, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this GLP-1 'fix' means hunger is unsuppressed, making overeating a significant risk."
A Lifelong Disease?
Health authorities suggest the jabs for individuals with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
Many experts contend that, due to the high risk of relapse, the treatment might need to be long-term.
This opinion is reinforced by pharmaceutical companies, who say that the findings "highlight the long-term nature of excess weight," akin to managing diseases like hypertension.
User Experiences
Users who have stopped the medication explain a sudden return of cravings.
"I experienced a trigger activating and you're instantly starving," said an individual.
This challenge is worsened if patients have not adopted sustainable lifestyle or habit changes during therapy.
Growing Interest
Survey data suggest that a significant number of people in the UK have tried weight-loss jabs in the past year, with desire being substantial.
- Adoption is higher among females compared to men.
- The 40s and 50s age group shows the highest usage rates.
- Many obtain the medications through private healthcare rather than the NHS.
Ultimately, clinicians caution that while the jabs are effective tools for shedding pounds, they are not a standalone cure and maintained weight loss hinges on combined behavioural support.
