New research reveals that people who come off popular slimming jabs like Mounjaro or Wegovy tend to recover lost weight much more quickly than those who end traditional diet and exercise regimens.
Findings released in a leading health publication demonstrates that while overweight individuals frequently drop a large proportion of their body weight while on the medication, the mass comes back at an estimated rate of 0.8 kg per month once they quit.
"Individuals purchasing these drugs must be aware of the danger of rapid weight regain when the medication is stopped," stated researcher Dr. Susan Jebb.
That rate of regain implies a reversion to pre-treatment weight within about one and a half years.
Comparing Treatments
The study, which examined dozens of studies involving thousands of patients, compared the outcomes of the injectable medications with other pills.
Researchers emphasize that people who lose weight through lifestyle changes alone typically have a less rapid creep back—approximately 0.1 kg a month—after stopping.
Understanding the Quick Regain
Nutrition scientists propose the mode of action of the drugs accounts for the heightened regain.
The injections imitate a natural hormone called GLP-1, which moderates hunger.
"Long-term administration of GLP-1 concentrations far above than normal might result in the system to produce less of its own natural hormone, and could lessen responsiveness to its actions," noted Dr. Adam Collins, a nutrition expert.
"Withdrawal of this GLP-1 'fix' results in hunger is unsuppressed, making excessive eating far more likely."
A Lifelong Issue?
Medical guidelines suggest the injections for people with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
Many experts contend that, considering the likelihood of weight regain, the therapy is often ongoing.
This perspective is echoed by pharmaceutical companies, who say that the results "emphasize the persistent nature of obesity," similar to managing conditions like diabetes.
Patient Testimonies
Individuals who have discontinued the medication describe a intense resurgence of hunger.
"It felt as if a switch flipping and you become starving," recalled an individual.
The struggle is exacerbated if users have not adopted permanent dietary or behavioural changes during therapy.
Widespread Use
Recent estimates show that a significant number of people in the UK have used weight-loss jabs in the past year, with desire being substantial.
- Use is greater among females than men.
- The middle-aged age group shows the highest level of interest.
- Many obtain the drugs through private healthcare rather than public health services.
Ultimately, clinicians caution that while these medications are effective tools for shedding pounds, they are not a magic fix and long-term success hinges on ongoing behavioural support.
