A recent study indicates that patients who come off popular GLP-1 drugs like Wegovy and Mounjaro can put back on lost weight at a significantly accelerated pace than those who stop traditional lifestyle regimens.
Research printed in a major health publication shows that while overweight individuals often shed a large proportion of their total mass while undergoing treatment, the weight returns at an average rate of nearly a kilo each month upon discontinuation.
"People buying such drugs need to be aware of the potential of quick rebound weight gain when the treatment ends," stated lead investigator Dr. Susan Jebb.
This pace of recovery implies a return to starting mass in about a year and a half.
Weighing Approaches
The study, which looked at 37 of studies involving over 9,000 of patients, compared the effects of these new drugs with other pills.
Researchers point out that individuals who shed pounds through lifestyle changes alone typically have a less rapid creep back—approximately 0.1 kg a month—post-intervention.
The Reason for the Fast Regain
Doctors propose the mechanism of the drugs is key to understanding the accelerated weight return.
GLP-1 drugs copy a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Long-term administration of the hormone levels several times higher than the body's typical production may cause the system to generate a reduced amount of its own natural hormone, and could reduce responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' means appetite is unsuppressed, making binge eating much more probable."
A Lifelong Disease?
The NHS suggest the jabs for people with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
A number of clinicians argue that, due to the high risk of weight regain, the therapy is often long-term.
This view is reinforced by drug manufacturers, who state that the findings "emphasize the long-term nature of obesity," akin to managing diseases like hypertension.
User Accounts
Users who have come off the jabs describe a sudden resurgence of cravings.
"It felt as if a trigger flipping and you're instantly extremely hungry," said an individual.
The struggle is worsened if patients have not developed permanent dietary or behavioural changes during treatment.
Widespread Use
Figures suggest that millions of people in the UK have tried weight-loss jabs in the past year, with interest being substantial.
- Use is higher among females compared to males.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Finally, researchers emphasize that while the jabs are potent tools for weight loss, they are not a permanent cure and long-term success relies on ongoing behavioural management.
