Fresh analysis suggests that patients who come off new GLP-1 drugs like semaglutide or tirzepatide can put back on shed pounds far faster than those who stop traditional lifestyle regimens.
Research printed in a leading health publication shows that while overweight people can lose about a fifth of their total mass while using the jabs, the weight comes back at an average rate of 0.8 kg per month after stopping.
"People purchasing these treatments should be informed of the potential of quick rebound weight gain when the treatment concludes," warns lead investigator Dr. Susan Jebb.
That rate of regain suggests a reversion to starting weight in about 18 months.
Weighing Approaches
The study, which reviewed dozens of trials involving thousands of patients, compared the outcomes of the injectable medications with conventional dieting.
Researchers note that individuals who shed pounds through dieting typically have a less rapid weight regain—perhaps 0.1 kg a month—once they finish.
The Reason for the Quick Rebound
Nutrition scientists believe the way of the jabs accounts for the heightened weight return.
These medications copy a natural hormone called glucagon-like peptide-1, which moderates appetite.
"Sustained high doses of the hormone concentrations far above than normal may cause the body to produce less of its own natural hormone, and could diminish sensitivity to its actions," noted Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this medication leads to appetite is unsuppressed, making overeating far more likely."
An Ongoing Disease?
Medical guidelines advise the jabs for individuals with obesity-related health risks, alongside prescribed lifestyle changes.
Many experts contend that, due to the high risk of weight regain, the treatment might need to be long-term.
This opinion is supported by drug manufacturers, who note that the results "highlight the long-term nature of excess weight," akin to managing diseases like hypertension.
User Experiences
Individuals who have come off the medication report a intense resurgence of cravings.
"It felt as if something activating and you're instantly extremely hungry," described an individual.
The struggle is compounded if patients have not adopted lasting lifestyle or habit modifications during treatment.
Significant Interest
Figures suggest that a significant number of people in the UK have used these injections in the past year, with demand being substantial.
- Adoption is greater among females than males.
- The 40s and 50s demographic shows the highest usage rates.
- Many access the drugs through private prescriptions rather than the NHS.
Ultimately, researchers caution that while the jabs are potent agents for weight loss, they are not a magic fix and lasting health benefits relies on ongoing lifestyle management.
