Fresh analysis suggests that individuals who come off new slimming jabs like semaglutide or tirzepatide tend to recover lost weight far faster than those who halt conventional lifestyle programs.
Findings released in a leading health publication demonstrates that while overweight people frequently drop substantial amounts of their total mass while using the jabs, the weight is regained at an average rate of nearly a kilo each month once they quit.
"Individuals buying such medications need to be aware of the risk of fast weight regain when the medication ends," cautioned lead investigator Dr. Susan Jebb.
That rate of recovery suggests a return to pre-treatment weight within about a year and a half.
Weighing Treatments
The study, which looked at 37 of trials involving over 9,000 of patients, compared the outcomes of these new drugs with older methods.
Researchers point out that individuals who lose weight through diet and exercise generally see a slower creep back—perhaps 100 grams monthly—after stopping.
Understanding the Fast Regain
Nutrition scientists believe the way of the jabs is key to understanding the heightened rebound.
These medications imitate a natural hormone called glucagon-like peptide-1, which controls hunger.
"Artificially providing the hormone levels several times higher than the body's typical production may cause the system to produce less of its endogenous hormone, and may also lessen responsiveness to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this GLP-1 'fix' means hunger is unsuppressed, making excessive eating much more probable."
An Ongoing Condition?
Medical guidelines suggest the jabs for individuals with obesity-related health risks, accompanied by recommended lifestyle changes.
A number of clinicians argue that, considering the likelihood of relapse, the therapy is often long-term.
This view is supported by pharmaceutical companies, who say that the findings "emphasize the chronic nature of excess weight," similar to managing conditions like hypertension.
Patient Testimonies
Individuals who have come off the jabs explain a sudden return of appetite.
"It was like a switch that goes on and you're instantly extremely hungry," recalled an individual.
The struggle is worsened if patients have not developed lasting dietary or behavioural changes during therapy.
Widespread Adoption
Figures indicate that millions of adults in the UK have used these injections in the last 12 months, with desire continuing to grow.
- Adoption is higher among females compared to men.
- The 40s and 50s age group shows the highest level of interest.
- Many obtain the drugs through private prescriptions rather than the NHS.
Ultimately, clinicians caution that while the jabs are effective tools for weight loss, they are not a magic fix and maintained weight loss hinges on integrated behavioural support.
