Fresh analysis indicates that individuals who stop using new weight-loss injections like Mounjaro or Wegovy can put back on shed pounds far faster than those who stop traditional diet and exercise programs.
Published data in a prominent health publication shows that while obese individuals can lose a large proportion of their body weight while using the jabs, the weight is regained at an estimated rate of 0.8 kg per month once they quit.
"People purchasing these treatments must be aware of the danger of quick weight regain when the therapy is stopped," warns lead investigator Dr. Susan Jebb.
That rate of regain suggests a return to starting weight within about 18 months.
Analyzing Therapies
The research, which looked at 37 of studies involving thousands of participants, contrasted the outcomes of GLP-1 agonists with older methods.
Researchers point out that individuals who lose weight through dieting generally see a more gradual creep back—around 100 grams monthly—post-intervention.
Understanding the Fast Regain
Nutrition scientists propose the way of the injections is key to understanding the heightened weight return.
The injections copy a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Artificially providing the hormone levels far above than the body's typical production might result in the system to generate a reduced amount of its endogenous GLP-1, and may also reduce sensitivity to its effects," said Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this GLP-1 'fix' means hunger is no longer kept in check, making excessive eating a significant risk."
An Ongoing Disease?
Health authorities advise the injections for individuals with weight-linked health risks, alongside recommended lifestyle changes.
A number of clinicians argue that, considering the likelihood of weight regain, the therapy might need to be long-term.
This view is echoed by drug manufacturers, who note that the results "highlight the chronic nature of obesity," akin to managing diseases like high blood pressure.
User Testimonies
People who have come off the medication explain a sudden return of appetite.
"It felt as if something activating and I was suddenly starving," described an individual.
The struggle is compounded if patients have not adopted lasting lifestyle or habit modifications during therapy.
Growing Use
Survey data show that a significant number of people in the UK have used these injections in the past year, with desire remaining high.
- Use is higher among women than males.
- The middle-aged demographic shows the highest usage rates.
- A large proportion access the medications through private healthcare rather than the NHS.
In conclusion, experts emphasize that while GLP-1 drugs are effective tools for weight loss, they are not a permanent solution and maintained weight loss likely depends on integrated lifestyle support.
