Users Discontinuing Slimming Jabs Gain Back Pounds Far More Rapidly Than People Using Diet and Exercise
New research suggests that patients who discontinue new weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds far faster than those who stop traditional diet and exercise regimens.
Research printed in a leading health publication points out that while obese people frequently drop a large proportion of their body weight while undergoing treatment, the mass returns at an average rate of nearly a kilo each month upon discontinuation.
"People buying these treatments should be informed of the risk of rapid rebound weight gain when the treatment concludes," warns expert Dr. Susan Jebb.
Such speed of regain implies a return to original weight within about 18 months.
Weighing Treatments
The analysis, which looked at dozens of trials involving thousands of patients, contrasted the outcomes of these new drugs with conventional dieting.
Scientists point out that people who shed pounds through lifestyle changes alone typically experience a less rapid weight regain—around 0.1 kg a month—once they finish.
The Reason for the Quick Rebound
Doctors believe the way of the jabs explains the accelerated weight return.
These medications copy a body's own chemical called GLP-1, which helps regulate appetite.
"Sustained high doses of GLP-1 concentrations far above than the body's typical production might result in the system to generate a reduced amount of its endogenous hormone, and could lessen sensitivity to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this medication leads to hunger is uncontrolled, making overeating a significant risk."
An Ongoing Issue?
Health authorities suggest the jabs for individuals with obesity-related medical conditions, alongside recommended lifestyle changes.
Professionals argue that, given the high risk of weight regain, the treatment should be considered long-term.
This opinion is supported by drug manufacturers, who say that the results "highlight the persistent nature of excess weight," comparing it to managing conditions like hypertension.
Patient Testimonies
People who have come off the medication explain a intense return of appetite.
"It was like something activating and you become starving," recalled a patient.
The struggle is exacerbated if users have not established lasting lifestyle or habit changes during therapy.
Widespread Interest
Survey data indicate that millions of adults in the UK have used weight-loss jabs in the last 12 months, with interest remaining high.
- Adoption is greater among females compared to men.
- The 40s and 50s age group shows the highest usage rates.
- Many access the drugs through private healthcare rather than public health services.
Finally, clinicians caution that while the jabs are powerful tools for weight loss, they are not a permanent cure and lasting health benefits relies on integrated behavioural support.
