A recent study reveals that patients who stop using popular weight-loss injections like semaglutide or tirzepatide can put back on lost weight at a significantly accelerated pace than those who halt traditional lifestyle programs.
Published data in a major medical journal demonstrates that while overweight individuals can lose a large proportion of their total mass while using the jabs, the weight comes back at an average rate of 0.8 kg per month once they quit.
"Users using these treatments should be aware of the danger of rapid weight regain when the medication concludes," stated researcher Dr. Susan Jebb.
Such speed of recovery implies a return to starting mass in about 18 months.
Comparing Therapies
The study, which examined 37 of trials involving over 9,000 of patients, contrasted the outcomes of these new drugs with conventional dieting.
Scientists point out that individuals who shed pounds through lifestyle changes alone typically see a slower weight regain—around 100 grams monthly—post-intervention.
Understanding the Quick Rebound
Doctors believe the mode of action of the injections accounts for the amplified weight return.
The injections mimic a natural hormone called glucagon-like peptide-1, which helps regulate hunger.
"Long-term administration of the hormone concentrations several times higher than normal may cause the body to generate a reduced amount of its own natural GLP-1, and could lessen sensitivity to its effects," noted Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this GLP-1 'fix' means appetite is no longer kept in check, making overeating a significant risk."
A Chronic Condition?
The NHS recommend the injections for people with obesity-related health risks, alongside recommended diet and exercise modifications.
A number of clinicians contend that, due to the high risk of relapse, the therapy is often life-long.
This opinion is reinforced by pharmaceutical companies, who note that the results "underscore the long-term character of obesity," comparing it to managing diseases like high blood pressure.
User Accounts
People who have discontinued the medication report a intense return of appetite.
"It felt as if something flipping and you're instantly extremely hungry," recalled an individual.
The struggle is exacerbated if users have not developed lasting dietary or behavioural changes during treatment.
Widespread Adoption
Survey data suggest that a significant number of adults in the UK have tried weight-loss jabs in the past year, with interest being substantial.
- Use is greater among females compared to males.
- The middle-aged age group shows the highest usage rates.
- Many obtain the drugs through private healthcare rather than the NHS.
Ultimately, experts stress that while the jabs are potent agents for shedding pounds, they are not a standalone solution and maintained weight loss hinges on ongoing behavioural changes.
