A recent study reveals that individuals who come off blockbuster weight-loss injections like Mounjaro or Wegovy may regain shed pounds far faster than those who halt conventional lifestyle plans.
Research printed in a leading health publication shows that while overweight individuals can lose about a fifth of their body weight while undergoing treatment, the weight returns at an average rate of 0.8 kg per month after stopping.
"Users using such drugs need to be cognizant of the risk of quick rebound weight gain when the medication concludes," warns researcher Dr. Susan Jebb.
Such speed of regain means a return to pre-treatment weight within about one and a half years.
Weighing Approaches
The analysis, which examined dozens of studies involving over 9,000 of patients, compared the effects of these new drugs with older methods.
Scientists point out that individuals who lose weight through diet and exercise typically see a less rapid weight regain—perhaps 0.1 kg a month—after stopping.
Understanding the Rapid Regain
Nutrition scientists propose the mode of action of the drugs explains the accelerated rebound.
The injections copy a body's own chemical called GLP-1, which helps regulate hunger.
"Long-term administration of the hormone concentrations far above than normal may cause the system to generate a reduced amount of its endogenous GLP-1, and could diminish responsiveness to its actions," said Dr. Adam Collins, a nutrition expert.
"Withdrawal of this GLP-1 'fix' leads to hunger is unsuppressed, making overeating far more likely."
A Chronic Condition?
The NHS suggest the jabs for individuals with obesity-related health risks, alongside prescribed lifestyle changes.
Many experts argue that, considering the significant potential of weight regain, the therapy might need to be life-long.
This view is echoed by pharmaceutical companies, who note that the findings "highlight the chronic character of excess weight," comparing it to managing diseases like hypertension.
User Testimonies
Individuals who have come off the jabs report a intense resurgence of appetite.
"I experienced a trigger flipping and I was suddenly extremely hungry," recalled a patient.
This difficulty is compounded if individuals have not adopted lasting lifestyle or habit changes during treatment.
Widespread Adoption
Recent estimates show that millions of adults in the UK have used weight-loss jabs in the last 12 months, with interest remaining high.
- Adoption is more common among females than males.
- The 40s and 50s demographic shows the highest level of interest.
- Many access the drugs through private healthcare rather than public health services.
Finally, researchers stress that while these medications are potent tools for shedding pounds, they are not a magic solution and maintained weight loss hinges on combined lifestyle support.
