New research suggests that individuals who come off new slimming jabs like semaglutide or tirzepatide can put back on reduced body mass far faster than those who stop conventional lifestyle regimens.
Research printed in a prominent health publication demonstrates that while overweight people frequently drop a large proportion of their total mass while undergoing treatment, the weight returns at an estimated rate of 0.8 kg per month after stopping.
"Individuals buying such treatments should be informed of the danger of quick rebound weight gain when the treatment ends," cautioned expert Dr. Susan Jebb.
That rate of recovery implies a return to original mass in about 18 months.
Analyzing Treatments
The study, which examined 37 of studies involving over 9,000 of patients, contrasted the outcomes of GLP-1 agonists with older methods.
The team point out that individuals who lose weight through lifestyle changes alone usually have a slower weight regain—perhaps 100 grams monthly—once they finish.
Explaining the Quick Rebound
Doctors propose the mode of action of the injections accounts for the heightened rebound.
These medications mimic a natural hormone called GLP-1, which controls feelings of fullness.
"Long-term administration of the hormone concentrations several times higher than normal could lead to the system to produce less of its endogenous GLP-1, and may also diminish sensitivity to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this medication means appetite is uncontrolled, making overeating a significant risk."
An Ongoing Condition?
Medical guidelines recommend the jabs for people with weight-linked health risks, accompanied by recommended diet and exercise modifications.
A number of clinicians contend that, given the significant potential of relapse, the treatment is often life-long.
This view is echoed by pharmaceutical companies, who note that the results "emphasize the persistent character of obesity," similar to managing diseases like hypertension.
Patient Experiences
Users who have stopped the medication explain a powerful resurgence of appetite.
"It felt as if a switch that goes on and you become extremely hungry," described a patient.
This difficulty is compounded if individuals have not developed sustainable lifestyle or habit modifications during treatment.
Widespread Interest
Figures suggest that a significant number of adults in the UK have tried these injections in the last 12 months, with demand remaining high.
- Use is greater among women compared to men.
- The middle-aged demographic shows the highest usage rates.
- Many access the medications through private healthcare rather than public health services.
Finally, experts caution that while the jabs are potent tools for weight loss, they are not a permanent fix and lasting health benefits likely depends on combined behavioural support.
