Fresh analysis reveals that patients who come off blockbuster weight-loss injections like Mounjaro or Wegovy can put back on lost weight at a significantly accelerated pace than those who end traditional diet and exercise regimens.
Published data in a prominent medical journal points out that while obese people can lose about a fifth of their total mass while undergoing treatment, the weight returns at an average rate of 0.8 kg per month once they quit.
"Individuals purchasing such treatments must be informed of the risk of fast weight regain when the medication ends," warns lead investigator Dr. Susan Jebb.
Such speed of recovery suggests a reversion to starting weight in about a year and a half.
Weighing Therapies
The study, which looked at dozens of studies involving thousands of participants, contrasted the results of these new drugs with older methods.
The team point out that people who lose weight through dieting generally see a less rapid weight regain—around 100 grams monthly—once they finish.
Understanding the Fast Regain
Experts suggest the mechanism of the injections is key to understanding the accelerated weight return.
The injections imitate a natural hormone called glucagon-like peptide-1, which controls hunger.
"Sustained high doses of the hormone levels several times higher than the body's typical production might result in the body to produce less of its endogenous hormone, and could reduce sensitivity to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' results in appetite is uncontrolled, making excessive eating much more probable."
An Ongoing Condition?
Health authorities advise the jabs for individuals with weight-linked health risks, accompanied by recommended diet and exercise modifications.
Many experts contend that, due to the significant potential of weight regain, the therapy should be considered life-long.
This view is echoed by pharmaceutical companies, who note that the results "highlight the long-term nature of obesity," akin to managing conditions like diabetes.
User Testimonies
Individuals who have come off the jabs explain a powerful resurgence of cravings.
"It felt as if something that goes on and you're instantly starving," recalled an individual.
This difficulty is compounded if patients have not developed lasting dietary or behavioural changes during therapy.
Significant Use
Figures show that millions of adults in the UK have tried weight-loss jabs in the past year, with interest being substantial.
- Use is greater among women than males.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion access the drugs through private prescriptions rather than public health services.
In conclusion, clinicians stress that while the jabs are effective agents for shedding pounds, they are not a magic cure and lasting health benefits likely depends on integrated lifestyle support.
