A recent study suggests that patients who stop using popular weight-loss injections like semaglutide or tirzepatide can put back on lost weight much more quickly than those who halt traditional diet and exercise regimens.
Findings released in a prominent health publication points out that while obese people can lose a large proportion of their body weight while undergoing treatment, the mass returns at an estimated rate of nearly a kilo each month after stopping.
"People using such treatments need to be informed of the danger of fast rebound weight gain when the treatment is stopped," cautioned researcher Dr. Susan Jebb.
Such speed of recovery implies a reversion to starting mass in about one and a half years.
Weighing Approaches
The study, which examined dozens of trials involving over 9,000 of patients, contrasted the results of GLP-1 agonists with other pills.
Scientists point out that individuals who shed pounds through lifestyle changes alone typically have a less rapid creep back—approximately 100 grams monthly—post-intervention.
Explaining the Rapid Regain
Experts believe the mechanism of the jabs accounts for the amplified weight return.
These medications mimic a body's own chemical called GLP-1, which moderates 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 hormone, and could diminish sensitivity to its actions," explained Dr. Adam Collins, a nutrition expert.
"Discontinuation of this medication results in appetite is uncontrolled, making excessive eating a significant risk."
A Chronic Issue?
Medical guidelines recommend the jabs for people with weight-linked health risks, accompanied by recommended diet and exercise modifications.
Professionals argue that, due to the high risk of relapse, the treatment should be considered ongoing.
This view is reinforced by drug manufacturers, who state that the findings "emphasize the long-term character of obesity," comparing it to managing conditions like diabetes.
User Experiences
Individuals who have come off the medication explain a powerful return of hunger.
"It was like a trigger flipping and you're instantly starving," described a patient.
This challenge is exacerbated if individuals have not established lasting dietary or behavioural modifications during therapy.
Significant Interest
Recent estimates indicate that millions of people in the UK have used weight-loss jabs in the past year, with interest remaining high.
- Adoption is higher among females than men.
- The 40s and 50s age group shows the highest usage rates.
- Many access the medications through private prescriptions rather than public health services.
In conclusion, clinicians caution that while these medications are effective tools for shedding pounds, they are not a magic cure and long-term success hinges on ongoing behavioural support.
