Fresh analysis suggests that individuals who stop using popular GLP-1 drugs like Wegovy and Mounjaro tend to recover reduced body mass much more quickly than those who stop conventional lifestyle plans.
Research printed in a major medical journal demonstrates that while obese people frequently drop substantial amounts of their total mass while on the medication, the mass returns at an average rate of nearly a kilo each month once they quit.
"Users purchasing such drugs should be aware of the risk of rapid weight regain when the medication ends," cautioned expert Dr. Susan Jebb.
Such speed of regain means a return to pre-treatment mass within about 18 months.
Analyzing Therapies
The study, which looked at 37 of studies involving thousands of patients, contrasted the effects of these new drugs with older methods.
The team note that people who shed pounds through lifestyle changes alone typically experience a slower creep back—around 100 grams monthly—once they finish.
Understanding the Rapid Regain
Doctors propose the mode of action of the injections explains the accelerated rebound.
GLP-1 drugs mimic a natural hormone called GLP-1, which helps regulate hunger.
"Long-term administration of the hormone concentrations several times higher than the body's typical production may cause the system to generate a reduced amount of its own natural GLP-1, and could reduce responsiveness to its effects," said Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement results in hunger is no longer kept in check, making overeating much more probable."
An Ongoing Condition?
The NHS suggest the jabs for people with weight-linked health risks, accompanied by prescribed lifestyle changes.
Many experts contend that, considering the high risk of relapse, the treatment might need to be life-long.
This perspective is supported by pharmaceutical companies, who say that the results "emphasize the long-term character of excess weight," comparing it to managing conditions like hypertension.
User Experiences
Users who have stopped the jabs report a intense resurgence of hunger.
"I experienced something activating and I was suddenly extremely hungry," said an individual.
The struggle is worsened if users have not established sustainable dietary or behavioural changes during treatment.
Growing Interest
Recent estimates suggest that a significant number of adults in the UK have used weight-loss jabs in the last 12 months, with demand being substantial.
- Use is greater among females than men.
- The middle-aged age group shows the highest usage rates.
- A large proportion obtain the medications through private healthcare rather than public health services.
In conclusion, clinicians stress that while the jabs are potent tools for weight loss, they are not a permanent fix and lasting health benefits relies on ongoing behavioural support.
