Users Coming Off Anti-Obesity Injections Gain Back Weight Four Times Faster Than Dieters
A recent study indicates that individuals who come off blockbuster GLP-1 drugs like semaglutide or tirzepatide can put back on lost weight at a significantly accelerated pace than those who stop traditional lifestyle regimens.
Research printed in a major medical journal shows that while obese people often shed substantial amounts of their body weight while undergoing treatment, the mass is regained at an average rate of nearly a kilo each month after stopping.
"Individuals using such drugs need to be informed of the danger of quick rebound weight gain when the treatment ends," warns lead investigator Dr. Susan Jebb.
This pace of regain suggests a return to original weight within about one and a half years.
Weighing Approaches
The analysis, which examined 37 of trials involving over 9,000 of patients, contrasted the effects of the injectable medications with other pills.
Scientists emphasize that people who lose weight through dieting typically have a slower weight regain—approximately 100 grams monthly—once they finish.
Understanding the Fast Regain
Nutrition scientists propose the way of the jabs accounts for the accelerated regain.
GLP-1 drugs imitate a body's own chemical called GLP-1, which moderates appetite.
"Long-term administration of GLP-1 concentrations far above than the body's typical production may cause the system to generate a reduced amount of its endogenous GLP-1, and could lessen sensitivity to its effects," said Dr. Adam Collins, a dietetics researcher.
"Stopping of this GLP-1 'fix' means appetite is unsuppressed, making binge eating a significant risk."
An Ongoing Disease?
Health authorities recommend the jabs for people with obesity-related health risks, alongside recommended diet and exercise modifications.
Professionals contend that, due to the likelihood of weight regain, the therapy might need to be long-term.
This opinion is supported by drug manufacturers, who note that the findings "emphasize the persistent character of excess weight," similar to managing diseases like diabetes.
Patient Testimonies
Individuals who have stopped the medication report a sudden resurgence of cravings.
"It was like something flipping and you're instantly starving," said an individual.
The struggle is worsened if users have not developed sustainable lifestyle or habit modifications during treatment.
Widespread Interest
Figures suggest that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with demand remaining high.
- Use is higher among women than males.
- The middle-aged age group shows the highest level of interest.
- Many obtain the drugs through private healthcare rather than the NHS.
Ultimately, researchers caution that while these medications are effective tools for shedding pounds, they are not a magic fix and lasting health benefits hinges on ongoing lifestyle management.
