Fresh analysis reveals that people who discontinue new weight-loss injections like Mounjaro or Wegovy may regain lost weight far faster than those who end traditional lifestyle plans.
Findings released in a leading medical journal demonstrates that while overweight individuals often shed 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 once they quit.
"People using these drugs must be informed of the risk of rapid rebound weight gain when the treatment is stopped," warns lead investigator Dr. Susan Jebb.
This pace of regain suggests a return to starting mass within about 18 months.
Comparing Approaches
The analysis, which looked at dozens of trials involving over 9,000 of patients, compared the effects of these new drugs with older methods.
Researchers emphasize that individuals who lose weight through diet and exercise generally see a less rapid creep back—approximately 100 grams monthly—after stopping.
Understanding the Fast Rebound
Nutrition scientists believe the way of the jabs explains the accelerated weight return.
The injections imitate a body's own chemical called GLP-1, which helps regulate hunger.
"Long-term administration of GLP-1 concentrations far above than the body's typical production could lead to the body to generate a reduced amount of its own natural hormone, and may also lessen responsiveness to its effects," said Dr. Adam Collins, a dietetics expert.
"Withdrawal of this medication means appetite is uncontrolled, making binge eating much more probable."
A Lifelong Disease?
The NHS advise the jabs for people with weight-linked health risks, alongside prescribed lifestyle changes.
Many experts argue that, considering the likelihood of weight regain, the therapy should be considered life-long.
This perspective is reinforced by drug manufacturers, who note that the results "emphasize the long-term character of obesity," akin to managing diseases like diabetes.
User Experiences
Users who have stopped the medication explain a intense return of cravings.
"I experienced a trigger flipping and you're instantly extremely hungry," recalled a patient.
The struggle is compounded if patients have not established lasting lifestyle or habit modifications during treatment.
Significant Interest
Recent estimates indicate that a significant number of adults in the UK have used weight-loss jabs in the last 12 months, with interest being substantial.
- Use is higher among women than males.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion access the drugs through private prescriptions rather than public health services.
In conclusion, researchers caution that while GLP-1 drugs are potent tools for shedding pounds, they are not a permanent solution and long-term success likely depends on ongoing lifestyle management.
