Fresh analysis indicates that patients who stop using blockbuster slimming jabs like semaglutide or tirzepatide tend to recover shed pounds far faster than those who halt traditional diet and exercise plans.
Research printed in a prominent health publication shows that while obese individuals frequently drop a large proportion of their body weight while on the medication, the weight comes back at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals buying such drugs must be informed of the risk of quick rebound weight gain when the treatment is stopped," warns lead investigator Dr. Susan Jebb.
This pace of regain means a return to pre-treatment mass in about a year and a half.
Weighing Approaches
The analysis, which examined dozens of trials involving over 9,000 of patients, contrasted the outcomes of the injectable medications with conventional dieting.
Researchers note that individuals who lose weight through diet and exercise typically experience a less rapid weight regain—around 0.1 kg a month—once they finish.
Understanding the Fast Rebound
Experts believe the mechanism of the drugs explains the accelerated weight return.
These medications imitate a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.
"Sustained high doses of GLP-1 levels far above than the body's typical production might result in the body to generate a reduced amount of its own natural GLP-1, and may also lessen sensitivity to its actions," said Dr. Adam Collins, a dietetics expert.
"Withdrawal of this GLP-1 'fix' means appetite is unsuppressed, making binge eating a significant risk."
An Ongoing Condition?
Health authorities advise the jabs for individuals with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
Many experts say that, due to the high risk of relapse, the therapy should be considered ongoing.
This perspective is reinforced by pharmaceutical companies, who note that the findings "highlight the long-term character of obesity," similar to managing conditions like hypertension.
Patient Experiences
Individuals who have stopped the jabs report a powerful return of cravings.
"It felt as if something flipping and you become ravenous," described an individual.
The struggle is compounded if users have not developed sustainable lifestyle or habit modifications during treatment.
Significant Use
Recent estimates suggest that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with desire continuing to grow.
- Use is more common among women than males.
- The middle-aged age group shows the greatest level of interest.
- A large proportion access the drugs through private healthcare rather than public health services.
In conclusion, researchers caution that while the jabs are powerful agents for weight loss, they are not a magic solution and maintained weight loss hinges on ongoing lifestyle support.
