A recent study suggests that individuals who stop using new weight-loss injections like semaglutide or tirzepatide can put back on reduced body mass far faster than those who end conventional lifestyle regimens.
Findings released in a major health publication demonstrates that while overweight people often shed substantial amounts of their total mass while using the jabs, the weight comes back at an average rate of nearly a kilo each month after stopping.
"Individuals using these drugs must be aware of the potential of rapid weight regain when the treatment ends," stated expert Dr. Susan Jebb.
This pace of recovery suggests a return to starting weight in about 18 months.
Comparing Approaches
The study, which looked at 37 of trials involving thousands of patients, contrasted the outcomes of GLP-1 agonists with conventional dieting.
Scientists note that people who lose weight through diet and exercise usually have a slower creep back—around 100 grams monthly—post-intervention.
The Reason for the Fast Regain
Experts believe the way of the jabs accounts for the amplified weight return.
The injections imitate a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 levels far above than the body's typical production might result in the body to generate a reduced amount of its endogenous GLP-1, and could diminish responsiveness to its actions," said Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this GLP-1 'fix' leads to appetite is unsuppressed, making overeating a significant risk."
A Lifelong Disease?
Medical guidelines recommend the injections for people with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
A number of clinicians say that, given the high risk of weight regain, the treatment might need to be life-long.
This opinion is supported by drug manufacturers, who state that the results "emphasize the chronic nature of excess weight," akin to managing diseases like diabetes.
User Experiences
Users who have stopped the jabs describe a powerful resurgence of hunger.
"It felt as if a switch activating and you're instantly ravenous," recalled a patient.
The struggle is exacerbated if users have not developed sustainable dietary or behavioural changes during treatment.
Significant Adoption
Recent estimates indicate that a significant number of people in the UK have tried these injections in the last 12 months, with interest being substantial.
- Adoption is higher among women than men.
- The middle-aged demographic shows the greatest level of interest.
- Many access the medications through private healthcare rather than public health services.
Ultimately, clinicians stress that while the jabs are potent tools for shedding pounds, they are not a permanent cure and long-term success likely depends on integrated lifestyle support.
