Individuals Stopping Anti-Obesity Injections Put On Pounds Four Times Faster Than People Using Diet and Exercise

New research suggests that people who stop using new GLP-1 drugs like Wegovy and Mounjaro may regain shed pounds at a significantly accelerated pace than those who stop conventional lifestyle plans.

Published data in a prominent medical journal demonstrates that while overweight individuals frequently drop about a fifth of their total mass while using the jabs, the mass returns at an estimated rate of 0.8 kg per month upon discontinuation.

"Individuals using such treatments must be cognizant of the danger of rapid weight regain when the medication ends," warns researcher Dr. Susan Jebb.

That rate of regain implies a reversion to pre-treatment weight within about a year and a half.

Weighing Approaches

The analysis, which examined dozens of trials involving over 9,000 of participants, contrasted the outcomes of the injectable medications with other pills.

Researchers note that people who shed pounds through lifestyle changes alone generally experience a slower weight regain—around 0.1 kg a month—once they finish.

The Reason for the Fast Rebound

Nutrition scientists propose the mechanism of the injections is key to understanding the amplified weight return.

The injections copy a natural hormone called GLP-1, which moderates feelings of fullness.

"Long-term administration of the hormone levels far above than normal could lead to the body to generate a reduced amount of its own natural GLP-1, and could lessen responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.

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

An Ongoing Issue?

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

Many experts contend that, considering the likelihood of weight regain, the therapy might need to be ongoing.

This opinion is supported by pharmaceutical companies, who say that the results "highlight the long-term nature of excess weight," comparing it to managing diseases like high blood pressure.

Patient Testimonies

Users who have discontinued the jabs report a sudden return of cravings.

"I experienced a trigger activating and you become ravenous," described one woman.

This challenge is compounded if users have not established sustainable lifestyle or habit changes during treatment.

Significant Adoption

Figures show that millions of adults in the UK have tried weight-loss jabs in the past year, with demand remaining high.

• Use is more common among females than males.
• The 40s and 50s age group shows the highest usage rates.
• Many obtain the medications through private healthcare rather than public health services.

In conclusion, experts emphasize that while GLP-1 drugs are potent tools for shedding pounds, they are not a standalone fix and maintained weight loss likely depends on ongoing lifestyle management.
