A recent study reveals that individuals who stop using blockbuster weight-loss injections like Mounjaro or Wegovy may regain lost weight far faster than those who end conventional lifestyle plans.
Published data in a major medical journal points out that while obese individuals can lose a large proportion of their body weight while using the jabs, the weight comes back at an average rate of 0.8 kg per month upon discontinuation.
"People using these medications must be cognizant of the danger of fast weight regain when the medication concludes," cautioned lead investigator Dr. Susan Jebb.
Such speed of regain suggests a reversion to pre-treatment mass within about a year and a half.
Analyzing Approaches
The research, which looked at dozens of trials involving thousands of participants, compared the effects of the injectable medications with older methods.
Researchers note that individuals who lose weight through diet and exercise typically have a slower weight regain—perhaps 0.1 kg a month—post-intervention.
The Reason for the Quick Regain
Nutrition scientists believe the way of the jabs accounts for the accelerated regain.
The injections copy a body's own chemical called GLP-1, which controls appetite.
"Sustained high doses of the hormone levels several times higher than normal could lead to the body to generate a reduced amount of its endogenous GLP-1, and may also reduce sensitivity to its effects," said Dr. Adam Collins, a nutrition specialist.
"Stopping of this hormone supplement leads to hunger is no longer kept in check, making overeating a significant risk."
An Ongoing Condition?
The NHS suggest the injections for individuals with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
Professionals say that, considering the likelihood of weight regain, the therapy should be considered ongoing.
This view is reinforced by drug manufacturers, who state that the results "highlight the chronic nature of obesity," comparing it to managing diseases like high blood pressure.
Patient Testimonies
Users who have discontinued the medication report a intense return of cravings.
"I experienced something flipping and you're instantly extremely hungry," recalled one woman.
The struggle is exacerbated if users have not adopted permanent lifestyle or habit modifications during therapy.
Significant Interest
Figures suggest that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with demand remaining high.
- Adoption is higher among females than males.
- The middle-aged age group shows the highest usage rates.
- A large proportion access the medications through private healthcare rather than the NHS.
In conclusion, clinicians emphasize that while the jabs are potent agents for weight loss, they are not a standalone fix and long-term success hinges on ongoing lifestyle changes.
