Individuals Coming Off Slimming Medications Put On Weight Four Times Faster Compared to People Using Diet and Exercise

New research indicates that individuals who discontinue new weight-loss injections like semaglutide or tirzepatide may regain reduced body mass at a significantly accelerated pace than those who halt conventional lifestyle programs.

Findings released in a leading medical journal demonstrates that while overweight people can lose a large proportion of their total mass while using the jabs, the mass comes back at an average rate of 0.8 kg per month once they quit.

"Users purchasing such medications should be aware of the potential of quick rebound weight gain when the therapy is stopped," warns lead investigator Dr. Susan Jebb.

This pace of regain suggests a reversion to original weight in about 18 months.

Weighing Therapies

The research, which examined 37 of studies involving over 9,000 of patients, compared the results of the injectable medications with older methods.

Scientists note that people who lose weight through diet and exercise generally experience a slower creep back—approximately 100 grams monthly—once they finish.

The Reason for the Quick Rebound

Experts believe the mode of action of the injections is key to understanding the heightened weight return.

These medications mimic a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.

"Long-term administration of the hormone levels far above than the body's typical production could lead to the system to generate a reduced amount of its own natural hormone, and could reduce responsiveness to its actions," explained Dr. Adam Collins, a dietetics expert.

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

A Chronic Condition?

Health authorities suggest the injections for people with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.

Professionals argue that, considering the high risk of weight regain, the therapy is often ongoing.

This perspective is supported by drug manufacturers, who state that the findings "emphasize the persistent nature of obesity," comparing it to managing conditions like high blood pressure.

Patient Testimonies

Individuals who have come off the jabs explain a intense resurgence of hunger.

"I experienced a switch that goes on and you become ravenous," said one woman.

This difficulty is compounded if users have not adopted lasting lifestyle or habit modifications during treatment.

Growing Interest

Survey data suggest that millions of adults in the UK have used these injections in the last 12 months, with desire continuing to grow.

• Adoption is more common among females compared to men.
• The 40s and 50s age group shows the greatest level of interest.
• Many obtain the medications through private prescriptions rather than the NHS.

Ultimately, experts emphasize that while these medications are potent tools for shedding pounds, they are not a permanent fix and maintained weight loss hinges on combined behavioural changes.
