New research suggests that individuals who come off blockbuster slimming jabs like semaglutide or tirzepatide can put back on reduced body mass far faster than those who halt conventional diet and exercise regimens.
Published data in a major medical journal points out that while overweight people frequently drop a large proportion of their body weight while using the jabs, the mass is regained at an estimated rate of 0.8 kg per month after stopping.
"Individuals using such medications must be informed of the danger of fast weight regain when the medication ends," cautioned researcher Dr. Susan Jebb.
Such speed of recovery implies a reversion to pre-treatment mass in about 18 months.
Analyzing Therapies
The study, which reviewed dozens of studies involving over 9,000 of patients, compared the outcomes of the injectable medications with conventional dieting.
The team note that individuals who shed pounds through diet and exercise usually see a slower creep back—perhaps 100 grams monthly—post-intervention.
Understanding the Quick Rebound
Doctors believe the way of the injections explains the amplified rebound.
These medications imitate a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 concentrations far above than normal may cause the system to generate a reduced amount of its own natural GLP-1, and may also diminish sensitivity to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this GLP-1 'fix' leads to hunger is no longer kept in check, making overeating far more likely."
A Lifelong Issue?
Health authorities recommend the jabs for people with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Many experts say that, due to the significant potential of weight regain, the therapy might need to be life-long.
This opinion is supported by pharmaceutical companies, who note that the results "highlight the persistent nature of excess weight," comparing it to managing diseases like diabetes.
Patient Testimonies
People who have come off the medication explain a intense return of appetite.
"It was like a switch that goes on and I was suddenly ravenous," recalled one woman.
This difficulty is exacerbated if users have not developed sustainable lifestyle or habit modifications during therapy.
Widespread Interest
Recent estimates show that millions of adults in the UK have tried weight-loss jabs in the past year, with interest remaining high.
- Use is greater among females compared to males.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion access the drugs through private healthcare rather than the NHS.
In conclusion, researchers caution that while the jabs are effective agents for weight loss, they are not a standalone fix and lasting health benefits hinges on integrated behavioural support.
