New research reveals that people who discontinue new GLP-1 drugs like Mounjaro or Wegovy can put back on shed pounds much more quickly than those who halt traditional diet and exercise plans.
Published data in a prominent medical journal points out that while overweight individuals frequently drop substantial amounts of their body weight while on the medication, the mass returns at an estimated rate of 0.8 kg per month after stopping.
"Individuals using such treatments need to be informed of the potential of fast rebound weight gain when the medication ends," cautioned lead investigator Dr. Susan Jebb.
This pace of regain implies a return to original mass in about 18 months.
Comparing Treatments
The study, which reviewed 37 of trials involving over 9,000 of participants, contrasted the effects of these new drugs with other pills.
Scientists point out that people who lose weight through lifestyle changes alone generally have a slower weight regain—perhaps 0.1 kg a month—after stopping.
Explaining the Quick Rebound
Nutrition scientists suggest the mode of action of the injections accounts for the amplified regain.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.
"Artificially providing GLP-1 levels several times higher than normal may cause the body to produce less of its own natural GLP-1, and may also reduce responsiveness to its effects," said Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this medication results in appetite is uncontrolled, making overeating much more probable."
An Ongoing Disease?
The NHS suggest the injections for people with obesity-related medical conditions, accompanied by recommended lifestyle changes.
A number of clinicians contend that, due to the significant potential of weight regain, the treatment is often life-long.
This opinion is reinforced by pharmaceutical companies, who state that the results "underscore the persistent character of obesity," similar to managing conditions like hypertension.
User Accounts
People who have come off the jabs describe a intense resurgence of hunger.
"It was like a trigger that goes on and you're instantly starving," described an individual.
This difficulty is compounded if patients have not established lasting dietary or behavioural changes during treatment.
Widespread Adoption
Recent estimates show that a significant number of adults in the UK have tried these injections in the last 12 months, with demand being substantial.
- Adoption is greater among females than males.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the medications through private healthcare rather than public health services.
In conclusion, clinicians caution that while GLP-1 drugs are effective tools for weight loss, they are not a magic fix and long-term success hinges on integrated behavioural changes.
