Patients Stopping Anti-Obesity Medications Regain Pounds at a Quadrupled Rate Than Those on Conventional Diets

New research suggests that individuals who discontinue new weight-loss injections like semaglutide or tirzepatide may regain shed pounds much more quickly than those who end traditional diet and exercise regimens.

Research printed in a major medical journal points out that while overweight individuals often shed about a fifth of their body weight while undergoing treatment, the mass is regained at an average rate of 0.8 kg per month after stopping.

"Individuals buying such treatments must be cognizant of the risk of rapid weight regain when the therapy is stopped," warns researcher Dr. Susan Jebb.

This pace of recovery means a reversion to starting mass in about one and a half years.

Comparing Treatments

The analysis, which reviewed dozens of studies involving thousands of patients, compared the outcomes of these new drugs with other pills.

Researchers note that individuals who shed pounds through diet and exercise generally experience a less rapid creep back—perhaps 0.1 kg a month—after stopping.

The Reason for the Quick Rebound

Doctors suggest the way of the drugs accounts for the heightened regain.

GLP-1 drugs imitate a body's own chemical called GLP-1, which moderates appetite.

"Sustained high doses of GLP-1 levels several times higher than the body's typical production could lead to the body to generate a reduced amount of its own natural hormone, and could diminish responsiveness to its actions," said Dr. Adam Collins, a dietetics expert.

"Stopping of this GLP-1 'fix' means hunger is uncontrolled, making excessive eating much more probable."

A Lifelong Disease?

Health authorities suggest the injections for people with obesity-related health risks, accompanied by prescribed lifestyle changes.

Professionals say that, considering the likelihood of weight regain, the therapy is often ongoing.

This perspective is echoed by pharmaceutical companies, who note that the findings "highlight the long-term character of excess weight," akin to managing conditions like hypertension.

Patient Experiences

People who have come off the medication explain a intense return of cravings.

"It felt as if a switch that goes on and you become starving," said an individual.

This challenge is worsened if users have not established lasting lifestyle or habit changes during treatment.

Significant Interest

Figures indicate that a significant number of people in the UK have used these injections in the last 12 months, with interest remaining high.

• Use is higher among females compared to males.
• The 40s and 50s age group shows the highest level of interest.
• A large proportion obtain the drugs through private prescriptions rather than public health services.

In conclusion, experts emphasize that while GLP-1 drugs are effective tools for shedding pounds, they are not a permanent cure and maintained weight loss likely depends on integrated behavioural changes.
