New research suggests that patients who discontinue popular GLP-1 drugs like Mounjaro or Wegovy tend to recover lost weight at a significantly accelerated pace than those who end conventional diet and exercise programs.
Research printed in a major health publication demonstrates that while overweight people frequently drop a large proportion of their body weight while undergoing treatment, the weight comes back at an estimated rate of nearly a kilo each month once they quit.
"People buying these medications should be informed of the potential of quick weight regain when the treatment concludes," warns lead investigator Dr. Susan Jebb.
That rate of regain suggests a return to original mass in about a year and a half.
Analyzing Therapies
The research, which examined dozens of trials involving over 9,000 of patients, contrasted the effects of GLP-1 agonists with older methods.
Scientists point out that people who lose weight through lifestyle changes alone usually see a slower creep back—perhaps 100 grams monthly—after stopping.
Explaining the Fast Rebound
Experts believe the mechanism of the injections explains the amplified rebound.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Long-term administration of the hormone concentrations several times higher than normal may cause the body to generate a reduced amount of its endogenous hormone, and may also lessen responsiveness to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this medication leads to hunger is unsuppressed, making overeating far more likely."
An Ongoing Issue?
Medical guidelines suggest the jabs for individuals with obesity-related health risks, alongside prescribed lifestyle changes.
Professionals contend that, considering the high risk of weight regain, the treatment is often life-long.
This opinion is reinforced by pharmaceutical companies, who say that the findings "underscore the chronic nature of obesity," comparing it to managing conditions like high blood pressure.
User Experiences
Individuals who have stopped the medication describe a sudden return of hunger.
"It was like something that goes on and you become ravenous," described an individual.
This challenge is compounded if users have not developed permanent dietary or behavioural changes during therapy.
Widespread Adoption
Figures indicate that a significant number of people in the UK have used these injections in the last 12 months, with desire remaining high.
- Use is more common among women compared to men.
- The middle-aged age group shows the highest usage rates.
- Many obtain the drugs through private prescriptions rather than public health services.
In conclusion, experts emphasize that while these medications are effective tools for shedding pounds, they are not a permanent cure and lasting health benefits likely depends on integrated lifestyle management.
