Fresh analysis reveals that individuals who come off popular weight-loss injections like semaglutide or tirzepatide can put back on shed pounds much more quickly than those who halt traditional diet and exercise programs.
Findings released in a prominent medical journal shows that while overweight individuals can lose substantial amounts of their total mass while undergoing treatment, the mass comes back at an average rate of 0.8 kg per month after stopping.
"Individuals using these medications need to be aware of the potential of quick weight regain when the therapy ends," warns expert Dr. Susan Jebb.
Such speed of recovery suggests a return to starting mass within about one and a half years.
Analyzing Treatments
The research, which examined dozens of studies involving thousands of patients, contrasted the effects of the injectable medications with conventional dieting.
Researchers point out that people who lose weight through dieting generally see a less rapid creep back—around 100 grams monthly—once they finish.
Explaining the Rapid Rebound
Nutrition scientists believe the mode of action of the drugs is key to understanding the amplified rebound.
The injections imitate a natural hormone called GLP-1, which controls hunger.
"Long-term administration of the hormone levels far above than the body's typical production might result in the body to produce less of its own natural GLP-1, and could lessen responsiveness to its effects," explained Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' means hunger is unsuppressed, making excessive eating far more likely."
An Ongoing Disease?
Health authorities advise the jabs for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Professionals say that, given the significant potential of weight regain, the treatment might need to be ongoing.
This view is reinforced by pharmaceutical companies, who say that the findings "underscore the long-term character of excess weight," comparing it to managing diseases like hypertension.
Patient Testimonies
Individuals who have stopped the jabs explain a intense resurgence of hunger.
"It was like a trigger flipping and you become ravenous," said one woman.
This challenge is compounded if users have not developed lasting dietary or behavioural changes during therapy.
Growing Interest
Survey data show that a significant number of adults in the UK have tried weight-loss jabs in the past year, with interest continuing to grow.
- Adoption is greater among females than males.
- The 40s and 50s age group shows the greatest usage rates.
- Many obtain the drugs through private healthcare rather than the NHS.
In conclusion, researchers caution that while the jabs are powerful agents for weight loss, they are not a magic cure and long-term success relies on ongoing lifestyle changes.
