New research suggests that patients who come off popular weight-loss injections like semaglutide or tirzepatide can put back on lost weight at a significantly accelerated pace than those who stop conventional lifestyle plans.
Published data in a leading health publication shows that while overweight people can lose a large proportion of their body weight while undergoing treatment, the mass is regained at an average rate of nearly a kilo each month upon discontinuation.
"Users using these drugs should be cognizant of the risk of quick weight regain when the treatment is stopped," stated lead investigator Dr. Susan Jebb.
This pace of recovery implies a return to starting weight in about one and a half years.
Comparing Therapies
The research, which looked at dozens of studies involving thousands of patients, contrasted the effects of the injectable medications with other pills.
The team point out that individuals who shed pounds through dieting usually have a more gradual creep back—around 100 grams monthly—after stopping.
Explaining the Rapid Regain
Nutrition scientists suggest the mechanism of the injections explains the heightened rebound.
GLP-1 drugs mimic a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 levels far above than normal could lead to the body to generate a reduced amount of its own natural GLP-1, and may also lessen responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.
"Stopping of this GLP-1 'fix' leads to hunger is uncontrolled, making excessive eating much more probable."
A Chronic Condition?
Health authorities advise the jabs for individuals with obesity-related health risks, accompanied by prescribed diet and exercise modifications.
A number of clinicians say that, due to the likelihood of weight regain, the therapy should be considered long-term.
This view is reinforced by drug manufacturers, who note that the findings "highlight the persistent nature of obesity," comparing it to managing conditions like hypertension.
User Accounts
Individuals who have stopped the jabs describe a powerful resurgence of hunger.
"It was like a trigger that goes on and you're instantly ravenous," recalled a patient.
The struggle is worsened if individuals have not developed permanent lifestyle or habit changes during treatment.
Significant Adoption
Survey data suggest that millions of people in the UK have tried weight-loss jabs in the last 12 months, with interest continuing to grow.
- Adoption is greater among females than men.
- The 40s and 50s demographic shows the highest usage rates.
- Many obtain 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 standalone solution and lasting health benefits relies on combined lifestyle support.
