New research indicates that individuals who stop using new weight-loss injections like semaglutide or tirzepatide can put back on shed pounds much more quickly than those who halt traditional diet and exercise regimens.
Research printed in a major medical journal demonstrates that while overweight people often shed about a fifth of their total mass while undergoing treatment, the weight comes back at an average rate of nearly a kilo each month after stopping.
"People purchasing such treatments need to be informed of the potential of fast weight regain when the treatment ends," cautioned expert Dr. Susan Jebb.
That rate of regain implies a reversion to original weight within about one and a half years.
Weighing Therapies
The analysis, which examined dozens of trials involving over 9,000 of participants, contrasted the outcomes of GLP-1 agonists with older methods.
Researchers emphasize that individuals who lose weight through dieting generally see a slower creep back—approximately 100 grams monthly—after stopping.
Understanding the Fast Regain
Experts propose the mode of action of the drugs accounts for the heightened rebound.
GLP-1 drugs imitate a body's own chemical called GLP-1, which controls hunger.
"Long-term administration of the hormone concentrations several times higher than the body's typical production could lead to the system to produce less of its own natural GLP-1, and may also reduce responsiveness to its actions," explained Dr. Adam Collins, a dietetics expert.
"Stopping of this GLP-1 'fix' means appetite is no longer kept in check, making binge eating much more probable."
A Lifelong Condition?
Medical guidelines advise the injections for individuals with obesity-related health risks, accompanied by recommended diet and exercise modifications.
Professionals argue that, considering the significant potential of relapse, the treatment might need to be ongoing.
This opinion is supported by pharmaceutical companies, who note that the results "underscore the long-term nature of obesity," comparing it to managing conditions like hypertension.
Patient Accounts
People who have come off the medication describe a sudden resurgence of appetite.
"It was like a trigger activating and you become ravenous," recalled an individual.
The struggle is exacerbated if patients have not established lasting lifestyle or habit changes during therapy.
Significant Adoption
Figures indicate that millions of adults in the UK have used these injections in the past year, with demand being substantial.
- Adoption is greater among females than men.
- The 40s and 50s age group shows the highest level of interest.
- Many obtain the medications through private prescriptions rather than public health services.
In conclusion, researchers caution that while GLP-1 drugs are powerful agents for shedding pounds, they are not a standalone fix and long-term success hinges on ongoing behavioural support.
