Individuals Discontinuing Weight-Loss Medications Put On Weight Four Times Faster Compared to People Using Diet and Exercise
Fresh analysis indicates that patients who stop using popular weight-loss injections like Mounjaro or Wegovy tend to recover reduced body mass far faster than those who halt traditional lifestyle regimens.
Published data in a prominent medical journal shows that while overweight individuals can lose about a fifth of their body weight while on the medication, the mass returns at an average rate of 0.8 kg per month after stopping.
"Individuals buying these medications need to be cognizant of the risk of quick rebound weight gain when the treatment ends," cautioned lead investigator Dr. Susan Jebb.
Such speed of recovery means a reversion to starting mass in about a year and a half.
Analyzing Therapies
The research, which looked at 37 of studies involving over 9,000 of participants, contrasted the outcomes of these new drugs with other pills.
Scientists note that individuals who lose weight through dieting typically see a less rapid creep back—approximately 0.1 kg a month—once they finish.
Understanding the Quick Rebound
Nutrition scientists suggest the mechanism of the injections is key to understanding the heightened rebound.
These medications imitate a body's own chemical called GLP-1, which controls feelings of fullness.
"Long-term administration of GLP-1 concentrations far above than the body's typical production might result in the body to generate a reduced amount of its endogenous GLP-1, and may also lessen responsiveness to its effects," said Dr. Adam Collins, a dietetics expert.
"Stopping of this medication means hunger is no longer kept in check, making excessive eating far more likely."
An Ongoing Disease?
Health authorities advise the injections for individuals with weight-linked health risks, alongside recommended diet and exercise modifications.
Many experts argue that, given the likelihood of relapse, the therapy might need to be life-long.
This opinion is echoed by drug manufacturers, who state that the results "underscore the chronic character of obesity," akin to managing diseases like hypertension.
User Experiences
People who have stopped the jabs describe a sudden resurgence of appetite.
"It felt as if something flipping and you become starving," described an individual.
The struggle is compounded if patients have not adopted permanent lifestyle or habit modifications during treatment.
Widespread Use
Survey data suggest that millions of adults in the UK have tried these injections in the past year, with desire being substantial.
- Adoption is greater among women than men.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion access the drugs through private healthcare rather than public health services.
Finally, clinicians caution that while these medications are powerful tools for weight loss, they are not a permanent fix and maintained weight loss hinges on ongoing lifestyle management.
