Fresh analysis reveals that people who come off blockbuster weight-loss injections like Mounjaro or Wegovy tend to recover lost weight far faster than those who stop traditional lifestyle programs.
Research printed in a prominent medical journal points out that while overweight people frequently drop about a fifth of their total mass while undergoing treatment, the weight comes back at an estimated rate of 0.8 kg per month after stopping.
"Individuals buying such treatments must be informed of the risk of fast weight regain when the treatment concludes," cautioned lead investigator Dr. Susan Jebb.
That rate of regain implies a reversion to original weight in about 18 months.
Analyzing Therapies
The research, which examined 37 of studies involving thousands of participants, compared the effects of the injectable medications with other pills.
The team point out that people who shed pounds through dieting usually see a more gradual creep back—approximately 100 grams monthly—after stopping.
Understanding the Rapid Regain
Nutrition scientists propose the mode of action of the injections explains the heightened rebound.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which controls feelings of fullness.
"Sustained high doses of GLP-1 concentrations far above than the body's typical production could lead to the body to generate a reduced amount of its own natural GLP-1, and could diminish responsiveness to its actions," explained Dr. Adam Collins, a nutrition expert.
"Stopping of this medication results in hunger is no longer kept in check, making overeating far more likely."
An Ongoing Disease?
Health authorities advise the jabs for individuals with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians argue that, considering the likelihood of relapse, the therapy might need to be life-long.
This perspective is echoed by drug manufacturers, who state that the results "highlight the persistent character of obesity," similar to managing conditions like diabetes.
Patient Experiences
Users who have discontinued the medication describe a sudden return of cravings.
"It felt as if a trigger activating and I was suddenly starving," described an individual.
This challenge is worsened if patients have not established permanent lifestyle or habit modifications during treatment.
Significant Adoption
Recent estimates indicate that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with demand remaining high.
- Use is higher among women than men.
- The middle-aged demographic shows the highest level of interest.
- Many access the medications through private prescriptions rather than public health services.
In conclusion, experts stress that while these medications are powerful agents for weight loss, they are not a magic cure and maintained weight loss hinges on ongoing lifestyle support.
