Fresh analysis indicates that people who discontinue blockbuster GLP-1 drugs like Mounjaro or Wegovy can put back on lost weight far faster than those who halt traditional diet and exercise plans.
Research printed in a prominent medical journal shows that while overweight individuals often shed a large proportion of their body weight while on the medication, the mass is regained at an average rate of 0.8 kg per month upon discontinuation.
"Users purchasing these treatments need to be aware of the potential of quick weight regain when the therapy ends," stated expert Dr. Susan Jebb.
Such speed of regain implies a reversion to pre-treatment weight within about 18 months.
Comparing Approaches
The study, which looked at dozens of studies involving over 9,000 of participants, compared the effects of the injectable medications with other pills.
Scientists emphasize that individuals who lose weight through diet and exercise typically see a slower creep back—around 0.1 kg a month—after stopping.
Understanding the Fast Regain
Nutrition scientists believe the mode of action of the jabs explains the accelerated regain.
These medications mimic a natural hormone called GLP-1, which helps regulate appetite.
"Sustained high doses of GLP-1 concentrations several times higher than normal could lead to the system to generate a reduced amount of its own natural GLP-1, and could lessen sensitivity to its actions," said Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this GLP-1 'fix' leads to appetite is uncontrolled, making excessive eating a significant risk."
A Chronic Disease?
Medical guidelines advise the jabs for people with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Professionals argue that, due to the significant potential of weight regain, the treatment is often long-term.
This opinion is echoed by pharmaceutical companies, who note that the findings "highlight the chronic character of excess weight," comparing it to managing conditions like high blood pressure.
Patient Testimonies
People who have come off the medication describe a intense resurgence of cravings.
"I experienced a trigger flipping and I was suddenly ravenous," recalled an individual.
This challenge is exacerbated if individuals have not established sustainable dietary or behavioural modifications during therapy.
Significant Interest
Survey data suggest that millions of people in the UK have used these injections in the past year, with interest being substantial.
- Adoption is greater among females compared to males.
- The middle-aged demographic shows the greatest usage rates.
- Many obtain the medications through private prescriptions rather than public health services.
Finally, clinicians emphasize that while the jabs are effective agents for weight loss, they are not a permanent fix and lasting health benefits relies on ongoing lifestyle support.
