A recent study indicates that individuals who discontinue blockbuster GLP-1 drugs like Wegovy and Mounjaro tend to recover lost weight at a significantly accelerated pace than those who halt traditional diet and exercise regimens.
Research printed in a prominent health publication shows that while overweight people often shed substantial amounts of their total mass while on the medication, the weight comes back at an average rate of nearly a kilo each month upon discontinuation.
"People using such treatments need to be informed of the potential of fast weight regain when the treatment is stopped," warns lead investigator Dr. Susan Jebb.
This pace of recovery suggests a reversion to original mass within about a year and a half.
Analyzing Therapies
The study, which reviewed dozens of studies involving thousands of patients, contrasted the outcomes of these new drugs with conventional dieting.
The team point out that individuals who lose weight through diet and exercise typically have a slower creep back—around 0.1 kg a month—once they finish.
The Reason for the Rapid Regain
Experts believe the mechanism of the injections accounts for the heightened rebound.
GLP-1 drugs imitate a body's own chemical called GLP-1, which moderates appetite.
"Sustained high doses of the hormone levels several times higher than normal could lead to the system to generate a reduced amount of its own natural hormone, and could diminish sensitivity to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this medication means hunger is unsuppressed, making overeating far more likely."
An Ongoing Issue?
The NHS suggest the injections for individuals with weight-linked health risks, alongside prescribed diet and exercise modifications.
A number of clinicians say that, due to the high risk of relapse, the therapy might need to be ongoing.
This perspective is echoed by pharmaceutical companies, who say that the results "emphasize the chronic nature of obesity," comparing it to managing conditions like diabetes.
Patient Accounts
People who have come off the jabs describe a intense return of hunger.
"It was like a switch that goes on and you're instantly extremely hungry," said one woman.
The struggle is exacerbated if users have not adopted lasting lifestyle or habit changes during treatment.
Growing Interest
Figures show that a significant number of adults in the UK have tried weight-loss jabs in the past year, with interest being substantial.
- Use is greater among women compared to men.
- The 40s and 50s age group shows the highest level of interest.
- A large proportion access the medications through private prescriptions rather than the NHS.
In conclusion, researchers caution that while GLP-1 drugs are potent agents for weight loss, they are not a magic fix and lasting health benefits relies on ongoing lifestyle support.
