Users Stopping Slimming Jabs Put On Weight Four Times Faster Than People Using Diet and Exercise

New research reveals that patients who discontinue popular slimming jabs like semaglutide or tirzepatide tend to recover lost weight much more quickly than those who halt traditional lifestyle regimens.

Published data in a leading medical journal demonstrates that while overweight people frequently drop about a fifth of their total mass while undergoing treatment, the mass returns at an estimated rate of nearly a kilo each month upon discontinuation.

"Users using such treatments should be aware of the danger of rapid rebound weight gain when the medication concludes," warns lead investigator Dr. Susan Jebb.

This pace of recovery means a return to original weight within about 18 months.

Weighing Treatments

The analysis, which examined 37 of trials involving over 9,000 of participants, contrasted the results of the injectable medications with conventional dieting.

The team note that individuals who lose weight through lifestyle changes alone typically experience a more gradual creep back—around 0.1 kg a month—after stopping.

Explaining the Quick Rebound

Experts believe the mechanism of the drugs explains the amplified weight return.

The injections mimic a body's own chemical called GLP-1, which helps regulate feelings of fullness.

"Long-term administration of GLP-1 levels far above than the body's typical production may cause the body to produce less of its own natural GLP-1, and may also diminish sensitivity to its actions," explained Dr. Adam Collins, a dietetics researcher.

"Stopping of this medication leads to appetite is unsuppressed, making binge eating much more probable."

An Ongoing Condition?

The NHS suggest the jabs for individuals with weight-linked health risks, accompanied by prescribed lifestyle changes.

A number of clinicians argue that, given the significant potential of relapse, the treatment should be considered life-long.

This perspective is supported by drug manufacturers, who say that the findings "emphasize the chronic nature of obesity," akin to managing diseases like hypertension.

Patient Experiences

People who have stopped the jabs report a sudden return of hunger.

"It was like a trigger activating and you become extremely hungry," said an individual.

The struggle is worsened if users have not developed sustainable dietary or behavioural changes during treatment.

Significant Adoption

Survey data indicate that millions of adults in the UK have used these injections in the past year, with demand continuing to grow.

• Adoption is more common among females than men.
• The middle-aged age group shows the greatest level of interest.
• Many access the medications through private healthcare rather than public health services.

Ultimately, clinicians caution that while the jabs are potent agents for shedding pounds, they are not a standalone fix and maintained weight loss likely depends on integrated lifestyle changes.
