Patients Discontinuing Weight-Loss Medications Put On Weight at a Quadrupled Rate Compared to People Using Diet and Exercise
Fresh analysis reveals that individuals who stop using blockbuster slimming jabs like semaglutide or tirzepatide can put back on reduced body mass far faster than those who halt conventional lifestyle programs.
Research printed in a leading medical journal points out that while obese people can lose about a fifth of their body weight while undergoing treatment, the mass comes back at an average rate of nearly a kilo each month once they quit.
"Users buying such drugs must be informed of the risk of rapid rebound weight gain when the therapy ends," cautioned expert Dr. Susan Jebb.
That rate of regain implies a reversion to pre-treatment weight in about a year and a half.
Comparing Approaches
The analysis, which looked at 37 of trials involving thousands of patients, contrasted the results of these new drugs with other pills.
Researchers emphasize that people who lose weight through dieting usually experience a less rapid creep back—approximately 0.1 kg a month—after stopping.
Explaining the Fast Regain
Doctors propose the mode of action of the injections is key to understanding the heightened rebound.
These medications mimic a body's own chemical called glucagon-like peptide-1, which controls feelings of fullness.
"Artificially providing the hormone levels far above than normal may cause the system to generate a reduced amount of its own natural hormone, and could lessen sensitivity to its actions," noted Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement results in appetite is uncontrolled, making excessive eating a significant risk."
A Chronic Disease?
The NHS advise the jabs for individuals with obesity-related health risks, alongside recommended diet and exercise modifications.
Many experts contend that, considering the high risk of relapse, the therapy is often ongoing.
This perspective is reinforced by pharmaceutical companies, who note that the results "emphasize the chronic nature of excess weight," akin to managing conditions like diabetes.
User Testimonies
People who have stopped the jabs explain a intense resurgence of hunger.
"I experienced something flipping and I was suddenly extremely hungry," recalled one woman.
This difficulty is exacerbated if patients have not developed lasting dietary or behavioural modifications during therapy.
Significant Use
Figures suggest that a significant number of adults in the UK have used weight-loss jabs in the past year, with interest being substantial.
- Adoption is greater among women than males.
- The middle-aged age group shows the highest usage rates.
- A large proportion obtain the medications through private healthcare rather than public health services.
Ultimately, researchers stress that while GLP-1 drugs are potent agents for shedding pounds, they are not a standalone cure and long-term success hinges on ongoing lifestyle changes.
