New research indicates that people who come off popular GLP-1 drugs like semaglutide or tirzepatide can put back on reduced body mass at a significantly accelerated pace than those who halt traditional lifestyle programs.
Published data in a leading health publication points out that while obese people often shed a large proportion of their total mass while undergoing treatment, the weight returns at an estimated rate of nearly a kilo each month upon discontinuation.
"Users using such treatments need to be informed of the danger of fast rebound weight gain when the medication is stopped," cautioned expert Dr. Susan Jebb.
Such speed of recovery suggests a reversion to pre-treatment weight within about one and a half years.
Analyzing Therapies
The study, which reviewed dozens of trials involving thousands of patients, contrasted the effects of these new drugs with older methods.
Researchers point out that people who shed pounds through diet and exercise generally experience a less rapid weight regain—perhaps 0.1 kg a month—post-intervention.
Explaining the Fast Regain
Experts propose the mode of action of the drugs is key to understanding the amplified rebound.
The injections imitate a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Long-term administration of the hormone concentrations far above than normal might result in the system to produce less of its endogenous hormone, and could diminish responsiveness to its actions," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement means appetite is unsuppressed, making overeating much more probable."
An Ongoing Issue?
Health authorities suggest the injections for individuals with weight-linked medical conditions, alongside recommended diet and exercise modifications.
Professionals argue that, given the significant potential of weight regain, the therapy might need to be ongoing.
This perspective is reinforced by drug manufacturers, who state that the findings "highlight the persistent character of excess weight," comparing it to managing diseases like diabetes.
Patient Testimonies
Users who have discontinued the jabs describe a powerful return of appetite.
"I experienced a switch flipping and you're instantly extremely hungry," described an individual.
This difficulty is worsened if users have not developed sustainable dietary or behavioural changes during treatment.
Widespread Adoption
Survey data suggest that a significant number of adults in the UK have used these injections in the past year, with demand remaining high.
- Use is greater among women compared to males.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion access the drugs through private prescriptions rather than public health services.
In conclusion, clinicians stress that while the jabs are potent tools for shedding pounds, they are not a permanent fix and lasting health benefits relies on ongoing behavioural changes.
