New research indicates that individuals who stop using new GLP-1 drugs like semaglutide or tirzepatide may regain shed pounds at a significantly accelerated pace than those who end conventional diet and exercise plans.
Findings released in a prominent health publication shows that while obese individuals can lose a large proportion of their body weight while on the medication, the weight comes back at an average rate of nearly a kilo each month upon discontinuation.
"Individuals using such treatments should be aware of the potential of rapid rebound weight gain when the therapy is stopped," cautioned researcher Dr. Susan Jebb.
This pace of regain suggests a reversion to starting mass in about one and a half years.
Weighing Treatments
The research, which reviewed 37 of studies involving over 9,000 of participants, contrasted the results of these new drugs with other pills.
Scientists note that people who lose weight through diet and exercise typically experience a slower creep back—approximately 100 grams monthly—post-intervention.
Explaining the Quick Rebound
Doctors suggest the way of the injections accounts for the heightened rebound.
GLP-1 drugs mimic a natural hormone called glucagon-like peptide-1, which controls feelings of fullness.
"Long-term administration of the hormone levels far above than the body's typical production could lead to the system to produce less of its endogenous GLP-1, and may also diminish sensitivity to its effects," said Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this hormone supplement means hunger is no longer kept in check, making binge eating much more probable."
A Chronic Condition?
Medical guidelines advise the jabs for individuals with weight-linked medical conditions, alongside recommended lifestyle changes.
Many experts say that, given the likelihood of weight regain, the treatment is often life-long.
This opinion is echoed by drug manufacturers, who note that the results "highlight the persistent character of excess weight," similar to managing diseases like diabetes.
Patient Testimonies
Individuals who have stopped the medication report a intense resurgence of cravings.
"It was like something that goes on and I was suddenly ravenous," recalled a patient.
This difficulty is worsened if users have not adopted sustainable lifestyle or habit modifications during treatment.
Growing Interest
Figures suggest that millions of adults in the UK have used these injections in the past year, with desire continuing to grow.
- Adoption is more common among females than males.
- The middle-aged age group shows the highest level of interest.
- Many access the medications through private prescriptions rather than public health services.
Ultimately, experts caution that while these medications are effective agents for weight loss, they are not a permanent solution and maintained weight loss hinges on ongoing behavioural changes.
