Patients Discontinuing Weight-Loss Jabs Gain Back Pounds Four Times Faster Compared to People Using Diet and Exercise

New research indicates that people who come off popular GLP-1 drugs like semaglutide or tirzepatide tend to recover reduced body mass far faster than those who end traditional lifestyle programs.

Published data in a major medical journal points out that while obese individuals frequently drop a large proportion of their body weight while on the medication, the mass returns at an estimated rate of nearly a kilo each month after stopping.

"Users purchasing these medications need to be aware of the potential of fast weight regain when the treatment is stopped," cautioned researcher Dr. Susan Jebb.

This pace of regain implies a return to pre-treatment weight within about 18 months.

Weighing Treatments

The research, which examined 37 of trials involving thousands of participants, contrasted the outcomes of the injectable medications with conventional dieting.

Scientists emphasize that individuals who shed pounds through dieting generally see a less rapid creep back—perhaps 0.1 kg a month—post-intervention.

Explaining the Fast Regain

Doctors suggest the mode of action of the drugs accounts for the amplified weight return.

The injections imitate a natural hormone called GLP-1, which helps regulate hunger.

"Artificially providing the hormone levels far above than the body's typical production might result in the body to produce less of its own natural hormone, and may also reduce responsiveness to its effects," noted Dr. Adam Collins, a dietetics researcher.

"Discontinuation of this medication means appetite is unsuppressed, making binge eating much more probable."

A Chronic Disease?

Medical guidelines recommend the jabs for people with obesity-related health risks, alongside prescribed lifestyle changes.

Many experts argue that, due to the high risk of weight regain, the treatment is often life-long.

This opinion is reinforced by drug manufacturers, who state that the findings "highlight the long-term nature of obesity," comparing it to managing diseases like hypertension.

User Testimonies

Individuals who have stopped the medication explain a sudden return of cravings.

"It felt as if a switch that goes on and I was suddenly starving," recalled an individual.

This challenge is compounded if users have not established sustainable dietary or behavioural changes during treatment.

Widespread Interest

Recent estimates suggest that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with interest remaining high.

• Use is more common among women compared to men.
• The middle-aged age group shows the highest level of interest.
• A large proportion obtain the medications through private prescriptions rather than the NHS.

In conclusion, experts stress that while these medications are potent tools for weight loss, they are not a magic cure and maintained weight loss relies on combined lifestyle support.
