A recent study reveals that patients who come off new weight-loss injections like Mounjaro or Wegovy tend to recover lost weight much more quickly than those who end traditional diet and exercise plans.
Published data in a prominent medical journal demonstrates that while obese people frequently drop substantial amounts of their body weight while using the jabs, the weight is regained at an average rate of 0.8 kg per month upon discontinuation.
"People purchasing such treatments need to be informed of the danger of fast rebound weight gain when the medication concludes," stated expert Dr. Susan Jebb.
That rate of recovery suggests a reversion to starting mass within about one and a half years.
Weighing Treatments
The research, which reviewed dozens of trials involving over 9,000 of patients, compared the outcomes of GLP-1 agonists with older methods.
Scientists emphasize that individuals who lose weight through lifestyle changes alone typically experience a less rapid creep back—perhaps 100 grams monthly—once they finish.
The Reason for the Fast Regain
Experts propose the mechanism of the jabs accounts for the amplified regain.
The injections mimic a body's own chemical called GLP-1, which moderates hunger.
"Long-term administration of the hormone levels far above than the body's typical production may cause the body to generate a reduced amount of its endogenous hormone, and could lessen responsiveness to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this hormone supplement leads to appetite is uncontrolled, making excessive eating a significant risk."
A Chronic Issue?
Health authorities recommend the jabs for individuals with obesity-related health risks, accompanied by recommended diet and exercise modifications.
Professionals say that, due to the high risk of weight regain, the therapy is often long-term.
This view is echoed by pharmaceutical companies, who say that the results "emphasize the persistent nature of obesity," akin to managing conditions like hypertension.
Patient Experiences
People who have stopped the medication explain a intense resurgence of hunger.
"It was like a trigger flipping and I was suddenly starving," said an individual.
The struggle is compounded if users have not adopted lasting lifestyle or habit modifications during treatment.
Growing Use
Survey data suggest that a significant number of adults in the UK have used weight-loss jabs in the past year, with interest continuing to grow.
- Use is more common among women than males.
- The 40s and 50s age group shows the highest level of interest.
- A large proportion obtain the drugs through private healthcare rather than public health services.
In conclusion, experts caution that while the jabs are powerful agents for weight loss, they are not a standalone solution and lasting health benefits hinges on ongoing behavioural changes.
