Patients Stopping Weight-Loss Injections Regain Weight Four Times Faster Compared to People Using Diet and Exercise

New research suggests that people who discontinue blockbuster slimming jabs like Wegovy and Mounjaro can put back on shed pounds far faster than those who end traditional diet and exercise programs.

Research printed in a prominent health publication points out that while obese people frequently drop substantial amounts of their total mass while on the medication, the mass comes back at an average rate of 0.8 kg per month after stopping.

"People purchasing these treatments need to be informed of the potential of quick rebound weight gain when the treatment concludes," warns expert Dr. Susan Jebb.

That rate of recovery implies a reversion to original weight within about 18 months.

Analyzing Treatments

The analysis, which looked at dozens of studies involving thousands of participants, contrasted the outcomes of the injectable medications with older methods.

The team note that individuals who shed pounds through diet and exercise usually experience a less rapid creep back—approximately 100 grams monthly—post-intervention.

Explaining the Quick Rebound

Experts believe the mode of action of the injections accounts for the amplified rebound.

These medications imitate a natural hormone called GLP-1, which moderates feelings of fullness.

"Artificially providing the hormone concentrations far above than normal could lead to the system to produce less of its own natural hormone, and could reduce sensitivity to its actions," said Dr. Adam Collins, a dietetics specialist.

"Stopping of this medication results in hunger is no longer kept in check, making excessive eating far more likely."

A Lifelong Issue?

Health authorities advise the jabs for people with obesity-related health risks, accompanied by recommended lifestyle changes.

Professionals argue that, considering the significant potential of weight regain, the therapy is often long-term.

This opinion is supported by pharmaceutical companies, who say that the results "emphasize the chronic character of excess weight," similar to managing conditions like high blood pressure.

Patient Accounts

Users who have discontinued the jabs describe a intense return of cravings.

"It was like a trigger activating and you're instantly ravenous," said one woman.

This challenge is worsened if patients have not developed lasting dietary or behavioural changes during treatment.

Widespread Use

Recent estimates suggest that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with desire being substantial.

• Adoption is more common among females than males.
• The 40s and 50s age group shows the highest level of interest.
• Many access the drugs through private prescriptions rather than the NHS.

In conclusion, researchers stress that while the jabs are effective tools for weight loss, they are not a permanent cure and maintained weight loss relies on ongoing lifestyle support.
