A recent study suggests that people who stop using blockbuster weight-loss injections like Mounjaro or Wegovy can put back on lost weight at a significantly accelerated pace than those who stop conventional diet and exercise plans.
Published data in a prominent health publication shows that while obese people can lose substantial amounts of their body weight while on the medication, the weight is regained at an average rate of 0.8 kg per month once they quit.
"People using such medications should be aware of the potential of quick rebound weight gain when the therapy concludes," cautioned researcher Dr. Susan Jebb.
Such speed of recovery means a reversion to starting mass in about a year and a half.
Comparing Treatments
The research, which looked at dozens of studies involving thousands of participants, compared the effects of the injectable medications with other pills.
Scientists note that people who shed pounds through lifestyle changes alone generally have a slower weight regain—approximately 100 grams monthly—post-intervention.
Understanding the Fast Rebound
Nutrition scientists believe the mechanism of the injections is key to understanding the amplified rebound.
These medications copy a body's own chemical called glucagon-like peptide-1, which helps regulate hunger.
"Sustained high doses of GLP-1 levels several times higher than the body's typical production may cause the system to generate a reduced amount of its endogenous hormone, and may also reduce sensitivity to its effects," noted Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this hormone supplement leads to appetite is uncontrolled, making binge eating much more probable."
An Ongoing Issue?
Health authorities recommend the jabs for individuals with weight-linked health risks, alongside recommended lifestyle changes.
Professionals say that, due to the likelihood of weight regain, the therapy should be considered life-long.
This opinion is supported by drug manufacturers, who note that the results "emphasize the long-term character of obesity," comparing it to managing conditions like diabetes.
Patient Accounts
People who have stopped the medication describe a sudden resurgence of appetite.
"It felt as if a trigger flipping and you're instantly ravenous," described one woman.
This difficulty is compounded if users have not established sustainable lifestyle or habit modifications during treatment.
Growing Use
Survey data show that a significant number of adults in the UK have used these injections in the last 12 months, with demand being substantial.
- Adoption is more common among females compared to men.
- The middle-aged demographic shows the greatest level of interest.
- Many obtain the medications through private prescriptions rather than public health services.
In conclusion, experts caution that while the jabs are effective tools for shedding pounds, they are not a magic solution and long-term success hinges on integrated lifestyle management.
