New research suggests that patients who discontinue popular weight-loss injections like semaglutide or tirzepatide can put back on reduced body mass at a significantly accelerated pace than those who halt conventional lifestyle plans.
Findings released in a prominent health publication demonstrates that while obese individuals often shed substantial amounts of their total mass while using the jabs, the mass is regained at an estimated rate of nearly a kilo each month upon discontinuation.
"Users purchasing these medications need to be cognizant of the danger of fast weight regain when the medication ends," cautioned expert Dr. Susan Jebb.
Such speed of regain implies a return to pre-treatment weight within about 18 months.
Weighing Approaches
The research, which examined dozens of trials involving thousands of patients, contrasted the effects of these new drugs with conventional dieting.
The team emphasize that people who lose weight through lifestyle changes alone usually have a less rapid weight regain—around 0.1 kg a month—after stopping.
The Reason for the Fast Rebound
Nutrition scientists suggest the way of the injections explains the accelerated rebound.
GLP-1 drugs copy a natural hormone called GLP-1, which controls hunger.
"Long-term administration of the hormone levels several times higher than normal may cause the body to produce less of its endogenous hormone, and could lessen sensitivity to its actions," noted Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this medication leads to appetite is uncontrolled, making excessive eating much more probable."
A Lifelong Issue?
Medical guidelines suggest the jabs for people with obesity-related medical conditions, alongside prescribed lifestyle changes.
Professionals argue that, given the high risk of weight regain, the treatment should be considered ongoing.
This view is reinforced by drug manufacturers, who note that the results "highlight the chronic character of obesity," similar to managing conditions like hypertension.
Patient Accounts
People who have come off the jabs describe a sudden return of hunger.
"It felt as if a switch that goes on and you become ravenous," recalled a patient.
The struggle is worsened if individuals have not adopted lasting dietary or behavioural changes during therapy.
Growing Interest
Recent estimates show that millions of people in the UK have tried weight-loss jabs in the past year, with desire continuing to grow.
- Use is more common among females than males.
- The 40s and 50s age group shows the highest level of interest.
- Many obtain the medications through private prescriptions rather than public health services.
In conclusion, researchers emphasize that while these medications are powerful tools for shedding pounds, they are not a magic cure and lasting health benefits hinges on integrated lifestyle support.
