New research reveals that individuals who come off new slimming jabs like Mounjaro or Wegovy tend to recover reduced body mass much more quickly than those who halt traditional lifestyle programs.
Research printed in a leading health publication shows that while overweight individuals can lose about a fifth of their body weight while using the jabs, the weight returns at an estimated rate of 0.8 kg per month upon discontinuation.
"Users buying such medications should be aware of the potential of fast rebound weight gain when the medication is stopped," stated researcher Dr. Susan Jebb.
That rate of regain suggests a reversion to starting weight within about one and a half years.
Analyzing Therapies
The study, which reviewed 37 of studies involving thousands of participants, contrasted the results of GLP-1 agonists with older methods.
Scientists note that individuals who shed pounds through diet and exercise generally have a slower weight regain—approximately 100 grams monthly—once they finish.
Understanding the Fast Rebound
Nutrition scientists propose the mode of action of the jabs is key to understanding the heightened rebound.
These medications mimic a body's own chemical called glucagon-like peptide-1, which helps regulate hunger.
"Sustained high doses of the hormone concentrations far above than the body's typical production may cause the body to generate a reduced amount of its own natural GLP-1, and may also reduce responsiveness to its actions," said Dr. Adam Collins, a nutrition expert.
"Stopping of this medication means hunger is uncontrolled, making overeating a significant risk."
An Ongoing Disease?
Health authorities suggest the injections for individuals with weight-linked health risks, alongside prescribed diet and exercise modifications.
A number of clinicians argue that, due to the high risk of relapse, the treatment might need to be life-long.
This perspective is reinforced by pharmaceutical companies, who state that the results "emphasize the chronic character of excess weight," similar to managing conditions like diabetes.
Patient Accounts
Users who have discontinued the medication report a intense return of cravings.
"I experienced a trigger activating and you're instantly ravenous," described a patient.
This challenge is exacerbated if users have not developed sustainable dietary or behavioural changes during therapy.
Growing Use
Recent estimates indicate that millions of people in the UK have used weight-loss jabs in the last 12 months, with interest being substantial.
- Use is greater among women than males.
- The middle-aged age group shows the highest usage rates.
- A large proportion access the drugs through private prescriptions rather than the NHS.
In conclusion, researchers stress that while the jabs are powerful tools for weight loss, they are not a standalone fix and lasting health benefits likely depends on integrated behavioural management.
