A recent study indicates that patients who come off new weight-loss injections like semaglutide or tirzepatide can put back on shed pounds much more quickly than those who stop conventional lifestyle plans.
Research printed in a major medical journal shows that while overweight individuals often shed about a fifth of their body weight while using the jabs, the mass is regained at an average rate of 0.8 kg per month once they quit.
"Users purchasing these treatments need to be aware of the danger of fast rebound weight gain when the treatment ends," cautioned researcher Dr. Susan Jebb.
Such speed of regain implies a reversion to starting mass in about a year and a half.
Analyzing Therapies
The study, which examined dozens of trials involving over 9,000 of participants, contrasted the effects of the injectable medications with other pills.
Researchers note that individuals who shed pounds through lifestyle changes alone usually see a slower creep back—approximately 0.1 kg a month—after stopping.
Understanding the Fast Regain
Nutrition scientists propose the way of the jabs is key to understanding the heightened rebound.
These medications imitate a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Artificially providing the hormone concentrations several times higher than normal could lead to the system to produce less of its endogenous hormone, and may also diminish responsiveness to its effects," noted Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this GLP-1 'fix' results in appetite is unsuppressed, making excessive eating a significant risk."
A Chronic Condition?
Health authorities advise the injections for people with weight-linked health risks, accompanied by prescribed lifestyle changes.
Professionals contend that, given the likelihood of relapse, the therapy should be considered life-long.
This opinion is echoed by drug manufacturers, who note that the results "highlight the long-term character of excess weight," comparing it to managing diseases like hypertension.
User Testimonies
Users who have stopped the jabs describe a intense resurgence of cravings.
"It was like a switch activating and I was suddenly starving," described a patient.
This challenge is compounded if users have not developed sustainable dietary or behavioural changes during treatment.
Growing Use
Recent estimates suggest that millions of people in the UK have used these injections in the past year, with demand continuing to grow.
- Use is higher among women than males.
- The middle-aged demographic shows the highest level of interest.
- A large proportion access the medications through private prescriptions rather than public health services.
Finally, clinicians caution that while these medications are potent tools for shedding pounds, they are not a magic solution and maintained weight loss relies on ongoing lifestyle changes.
