New research suggests that patients who stop using new GLP-1 drugs like Wegovy and Mounjaro can put back on reduced body mass much more quickly than those who end traditional diet and exercise programs.
Research printed in a major health publication demonstrates that while overweight individuals can lose about a fifth of their body weight while undergoing treatment, the mass comes back at an estimated rate of nearly a kilo each month once they quit.
"Individuals purchasing such treatments need to be informed of the potential of fast rebound weight gain when the treatment ends," stated expert Dr. Susan Jebb.
Such speed of recovery implies a reversion to pre-treatment mass within about a year and a half.
Analyzing Treatments
The study, which reviewed dozens of studies involving thousands of participants, contrasted the effects of these new drugs with older methods.
Researchers emphasize that people who shed pounds through diet and exercise generally see a slower weight regain—perhaps 100 grams monthly—once they finish.
Understanding the Rapid Rebound
Nutrition scientists suggest the mechanism of the injections explains the heightened weight return.
GLP-1 drugs imitate a natural hormone called glucagon-like peptide-1, which moderates appetite.
"Sustained high doses of GLP-1 levels far above than the body's typical production might result in the system to generate a reduced amount of its own natural GLP-1, and may also diminish sensitivity to its effects," explained Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this GLP-1 'fix' results in hunger is no longer kept in check, making excessive eating much more probable."
A Chronic Condition?
Health authorities suggest the jabs for people with obesity-related medical conditions, alongside prescribed lifestyle changes.
Many experts argue that, due to the significant potential of weight regain, the treatment might need to be long-term.
This opinion is echoed by drug manufacturers, who state that the results "emphasize the persistent nature of excess weight," similar to managing conditions like hypertension.
User Accounts
People who have discontinued the medication describe a intense resurgence of cravings.
"I experienced a trigger that goes on and you become starving," recalled one woman.
This challenge is compounded if individuals have not developed lasting dietary or behavioural modifications during therapy.
Widespread Interest
Survey data indicate that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with demand continuing to grow.
- Use is greater among women compared to men.
- The 40s and 50s demographic shows the greatest level of interest.
- Many access the medications through private healthcare rather than the NHS.
In conclusion, researchers stress that while these medications are effective agents for weight loss, they are not a magic solution and lasting health benefits likely depends on combined lifestyle management.
