Fresh analysis indicates that individuals who discontinue blockbuster weight-loss injections like semaglutide or tirzepatide may regain shed pounds at a significantly accelerated pace than those who halt traditional diet and exercise regimens.
Published data in a major health publication shows that while obese individuals often shed a large proportion of their body weight while using the jabs, the mass comes back at an average rate of nearly a kilo each month upon discontinuation.
"Individuals buying these treatments need to be informed of the potential of quick weight regain when the therapy ends," cautioned researcher Dr. Susan Jebb.
That rate of regain means a return to original mass in about one and a half years.
Weighing Approaches
The research, which looked at 37 of trials involving over 9,000 of participants, compared the outcomes of the injectable medications with conventional dieting.
The team emphasize that individuals who lose weight through lifestyle changes alone usually see a slower weight regain—approximately 100 grams monthly—post-intervention.
The Reason for the Rapid Regain
Nutrition scientists believe the mechanism of the injections accounts for the heightened rebound.
The injections mimic a natural hormone called GLP-1, which moderates feelings of fullness.
"Sustained high doses of the hormone concentrations several times higher than normal might result in the system to generate a reduced amount of its endogenous hormone, and could reduce responsiveness to its effects," noted Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this hormone supplement results in hunger is no longer kept in check, making overeating far more likely."
A Chronic Disease?
Health authorities advise the injections for people with obesity-related health risks, alongside prescribed diet and exercise modifications.
Professionals say that, given the significant potential of relapse, the therapy should be considered ongoing.
This opinion is reinforced by pharmaceutical companies, who note that the results "highlight the chronic character of excess weight," comparing it to managing conditions like hypertension.
Patient Testimonies
People who have discontinued the medication describe a sudden resurgence of hunger.
"I experienced a switch that goes on and I was suddenly extremely hungry," said a patient.
This challenge is compounded if individuals have not adopted lasting dietary or behavioural changes during treatment.
Significant Interest
Recent estimates suggest that millions of people in the UK have tried these injections in the last 12 months, with desire remaining high.
- Use is higher among females compared to men.
- The 40s and 50s demographic shows the greatest level of interest.
- Many access the medications through private healthcare rather than public health services.
In conclusion, experts emphasize that while GLP-1 drugs are potent agents for shedding pounds, they are not a permanent fix and maintained weight loss likely depends on ongoing behavioural support.
