New research suggests that patients who stop using popular slimming jabs like semaglutide or tirzepatide may regain reduced body mass much more quickly than those who halt traditional lifestyle plans.
Published data in a prominent medical journal points out that while obese individuals can lose substantial amounts of their total mass while undergoing treatment, the weight is regained at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals using these drugs must be aware of the risk of rapid rebound weight gain when the therapy concludes," warns lead investigator Dr. Susan Jebb.
Such speed of regain implies a return to starting weight within about a year and a half.
Comparing Treatments
The analysis, which looked at 37 of studies involving over 9,000 of participants, compared the results of GLP-1 agonists with other pills.
Scientists point out that individuals who lose weight through lifestyle changes alone generally have a less rapid weight regain—perhaps 0.1 kg a month—after stopping.
The Reason for the Quick Regain
Nutrition scientists believe the mode of action of the jabs explains the amplified weight return.
The injections copy a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Long-term administration of the hormone levels far above than normal could lead to the body to generate a reduced amount of its own natural GLP-1, and may also lessen responsiveness to its actions," explained Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this hormone supplement means hunger is uncontrolled, making binge eating far more likely."
An Ongoing Condition?
The NHS recommend the injections for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians contend that, due to the high risk of weight regain, the treatment should be considered ongoing.
This perspective is supported by drug manufacturers, who note that the findings "underscore the persistent character of obesity," comparing it to managing conditions like high blood pressure.
User Testimonies
Individuals who have discontinued the medication describe a powerful return of cravings.
"It felt as if a trigger activating and you're instantly ravenous," described a patient.
This difficulty is exacerbated if patients have not developed lasting dietary or behavioural modifications during therapy.
Widespread Interest
Figures show that a significant number of adults in the UK have tried these injections in the last 12 months, with interest continuing to grow.
- Use is greater among females than males.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion access the drugs through private healthcare rather than public health services.
In conclusion, experts stress that while these medications are powerful agents for shedding pounds, they are not a permanent cure and maintained weight loss hinges on integrated lifestyle support.
