Patients Discontinuing Weight-Loss Injections Put On Weight at a Quadrupled Rate Than Dieters
Fresh analysis reveals that patients who come off popular GLP-1 drugs like semaglutide or tirzepatide tend to recover shed pounds at a significantly accelerated pace than those who end traditional lifestyle regimens.
Findings released in a prominent health publication points out that while overweight individuals often shed a large proportion of their total mass while on the medication, the weight is regained at an estimated rate of nearly a kilo each month once they quit.
"Individuals using these drugs need to be informed of the potential of rapid rebound weight gain when the medication concludes," warns lead investigator Dr. Susan Jebb.
That rate of regain implies a return to pre-treatment weight within about one and a half years.
Weighing Treatments
The study, which examined dozens of studies involving over 9,000 of patients, contrasted the outcomes of these new drugs with conventional dieting.
The team emphasize that people who shed pounds through diet and exercise generally experience a less rapid creep back—around 0.1 kg a month—once they finish.
The Reason for the Rapid Rebound
Nutrition scientists suggest the mechanism of the drugs is key to understanding the heightened rebound.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.
"Artificially providing the hormone concentrations far above than the body's typical production could lead to the body to produce less of its endogenous hormone, and may also reduce sensitivity to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this medication leads to hunger is unsuppressed, making overeating far more likely."
A Chronic Disease?
Health authorities suggest the injections for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians argue that, given the likelihood of weight regain, the therapy might need to be life-long.
This view is echoed by pharmaceutical companies, who state that the results "underscore the persistent nature of excess weight," akin to managing conditions like diabetes.
User Experiences
Users who have come off the jabs explain a powerful return of cravings.
"It felt as if something flipping and you become extremely hungry," said an individual.
The struggle is exacerbated if users have not adopted lasting dietary or behavioural changes during therapy.
Widespread Use
Recent estimates indicate that millions of people in the UK have used weight-loss jabs in the past year, with desire continuing to grow.
- Use is greater among females compared to men.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion access the drugs through private healthcare rather than the NHS.
Ultimately, experts stress that while these medications are effective agents for weight loss, they are not a permanent cure and lasting health benefits hinges on ongoing behavioural support.
