A recent study reveals that patients who stop using blockbuster slimming jabs like semaglutide or tirzepatide tend to recover shed pounds much more quickly than those who stop conventional lifestyle plans.
Published data in a leading health publication points out that while obese individuals often shed about a fifth of their body weight while using the jabs, the weight comes back at an estimated rate of nearly a kilo each month once they quit.
"People purchasing these drugs should be aware of the risk of fast rebound weight gain when the medication ends," stated researcher Dr. Susan Jebb.
This pace of recovery implies a reversion to pre-treatment weight in about 18 months.
Comparing Therapies
The study, which reviewed dozens of studies involving thousands of patients, compared the effects of the injectable medications with older methods.
The team emphasize that people who lose weight through lifestyle changes alone typically have a slower creep back—perhaps 0.1 kg a month—after stopping.
Understanding the Fast Regain
Experts propose the mode of action of the injections accounts for the amplified weight return.
The injections copy a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of the hormone levels several times higher than normal might result in the system to generate a reduced amount of its endogenous GLP-1, and could reduce sensitivity to its effects," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this GLP-1 'fix' leads to hunger is uncontrolled, making excessive eating far more likely."
An Ongoing Issue?
Medical guidelines advise the jabs for individuals with obesity-related medical conditions, alongside prescribed lifestyle changes.
A number of clinicians contend that, considering the likelihood of weight regain, the treatment is often life-long.
This opinion is reinforced by pharmaceutical companies, who state that the findings "highlight the long-term character of obesity," similar to managing diseases like hypertension.
Patient Experiences
People who have come off the medication report a intense return of appetite.
"It felt as if something activating and you become starving," recalled a patient.
This difficulty is worsened if patients have not adopted permanent lifestyle or habit modifications during treatment.
Growing Use
Figures indicate that millions of people in the UK have tried weight-loss jabs in the last 12 months, with demand continuing to grow.
- Adoption is greater among women compared to males.
- The 40s and 50s age group shows the greatest level of interest.
- Many access the medications through private prescriptions rather than the NHS.
Finally, experts emphasize that while these medications are potent agents for shedding pounds, they are not a permanent cure and lasting health benefits relies on integrated lifestyle management.
