Patients Coming Off Slimming Medications Put On Pounds Far More Rapidly Than Those on Conventional Diets

A recent study suggests that patients who discontinue blockbuster weight-loss injections like semaglutide or tirzepatide tend to recover lost weight at a significantly accelerated pace than those who end traditional lifestyle plans.

Research printed in a prominent medical journal points out that while overweight individuals often shed substantial amounts of their body weight while on the medication, the mass comes back at an estimated rate of 0.8 kg per month upon discontinuation.

"People using such drugs should be informed of the danger of fast rebound weight gain when the medication ends," cautioned expert Dr. Susan Jebb.

That rate of regain suggests a reversion to starting mass within about 18 months.

Comparing Treatments

The analysis, which looked at 37 of trials involving over 9,000 of participants, contrasted the effects of the injectable medications with older methods.

Scientists point out that individuals who lose weight through lifestyle changes alone usually experience a less rapid weight regain—around 0.1 kg a month—after stopping.

The Reason for the Fast Regain

Doctors suggest the mechanism of the drugs explains the heightened weight return.

These medications mimic a natural hormone called GLP-1, which controls hunger.

"Long-term administration of GLP-1 levels several times higher than normal could lead to the system to generate a reduced amount of its own natural hormone, and may also reduce responsiveness to its actions," explained Dr. Adam Collins, a nutrition researcher.

"Withdrawal of this medication leads to hunger is no longer kept in check, making binge eating far more likely."

A Chronic Disease?

Health authorities recommend the jabs for people with weight-linked health risks, accompanied by prescribed diet and exercise modifications.

Many experts contend that, given the high risk of relapse, the treatment might need to be ongoing.

This perspective is echoed by pharmaceutical companies, who state that the results "underscore the persistent character of obesity," akin to managing conditions like diabetes.

Patient Experiences

People who have discontinued the medication report a sudden return of cravings.

"It felt as if a trigger that goes on and I was suddenly extremely hungry," said one woman.

The struggle is compounded if users have not developed permanent lifestyle or habit changes during treatment.

Significant Use

Figures indicate that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with demand continuing to grow.

• Use is greater among females than males.
• The middle-aged demographic shows the greatest level of interest.
• Many obtain the medications through private prescriptions rather than the NHS.

In conclusion, researchers stress that while the jabs are powerful tools for shedding pounds, they are not a standalone fix and long-term success hinges on ongoing behavioural management.
