A recent study suggests that patients who come off blockbuster weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds far faster than those who end traditional diet and exercise plans.
Findings released in a major medical journal shows that while overweight people can lose substantial amounts of their body weight while undergoing treatment, the mass comes back at an estimated rate of 0.8 kg per month upon discontinuation.
"Users purchasing such drugs must be aware of the danger of quick rebound weight gain when the treatment is stopped," warns expert Dr. Susan Jebb.
This pace of regain implies a reversion to pre-treatment weight within about one and a half years.
Weighing Treatments
The analysis, which looked at 37 of studies involving over 9,000 of participants, compared the outcomes of the injectable medications with conventional dieting.
The team emphasize that individuals who lose weight through dieting usually have a slower creep back—around 100 grams monthly—once they finish.
Understanding the Rapid Regain
Doctors suggest the way of the drugs is key to understanding the heightened weight return.
The injections imitate a body's own chemical called glucagon-like peptide-1, which controls feelings of fullness.
"Sustained high doses of GLP-1 levels far above than the body's typical production may cause the system to produce less of its own natural hormone, and could lessen sensitivity to its actions," noted Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this hormone supplement means hunger is no longer kept in check, making binge eating much more probable."
An Ongoing Issue?
Medical guidelines suggest the jabs for individuals with obesity-related health risks, accompanied by prescribed lifestyle changes.
A number of clinicians contend that, considering the high risk of weight regain, the treatment might need to be long-term.
This view is reinforced by pharmaceutical companies, who say that the results "highlight the persistent character of obesity," comparing it to managing diseases like hypertension.
User Experiences
Users who have come off the jabs describe a intense resurgence of cravings.
"It felt as if a trigger activating and I was suddenly ravenous," recalled a patient.
This challenge is exacerbated if individuals have not developed permanent dietary or behavioural modifications during treatment.
Growing Interest
Survey data show that millions of adults in the UK have used these injections in the last 12 months, with interest remaining high.
- Use is higher among women than men.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion obtain the medications through private prescriptions rather than the NHS.
Ultimately, researchers emphasize that while GLP-1 drugs are effective agents for shedding pounds, they are not a magic cure and lasting health benefits likely depends on ongoing lifestyle support.
