Fresh analysis reveals that people who come off popular slimming jabs like Wegovy and Mounjaro tend to recover lost weight far faster than those who end conventional lifestyle regimens.
Published data in a prominent health publication demonstrates that while obese individuals can lose about a fifth of their total mass while using the jabs, the mass returns at an estimated rate of nearly a kilo each month after stopping.
"Individuals buying such treatments must be aware of the danger of rapid weight regain when the treatment is stopped," stated lead investigator Dr. Susan Jebb.
This pace of recovery implies a reversion to starting weight within about 18 months.
Comparing Approaches
The analysis, which examined dozens of studies involving thousands of participants, compared the results of these new drugs with other pills.
The team point out that people who shed pounds through lifestyle changes alone generally experience a less rapid weight regain—perhaps 100 grams monthly—once they finish.
Understanding the Fast Regain
Nutrition scientists believe the mechanism of the injections is key to understanding the accelerated regain.
These medications imitate a body's own chemical called GLP-1, which helps regulate hunger.
"Sustained high doses of GLP-1 concentrations far above than normal may cause the body to generate a reduced amount of its own natural GLP-1, and may also diminish responsiveness to its actions," noted Dr. Adam Collins, a dietetics expert.
"Discontinuation of this GLP-1 'fix' leads to appetite is uncontrolled, making overeating far more likely."
A Chronic Condition?
Medical guidelines recommend the injections for people with weight-linked health risks, alongside recommended diet and exercise modifications.
Many experts contend that, considering the likelihood of relapse, the therapy should be considered ongoing.
This perspective is echoed by drug manufacturers, who state that the findings "highlight the long-term character of excess weight," comparing it to managing diseases like high blood pressure.
Patient Experiences
People who have stopped the medication explain a intense return of hunger.
"It felt as if a switch activating and you become extremely hungry," recalled a patient.
The struggle is compounded if users have not developed lasting lifestyle or habit modifications during therapy.
Widespread Interest
Figures show that a significant number of adults in the UK have used these injections in the past year, with demand being substantial.
- Use is greater among women than males.
- The middle-aged demographic shows the greatest usage rates.
- A large proportion obtain the medications through private healthcare rather than the NHS.
Ultimately, experts caution that while the jabs are potent agents for shedding pounds, they are not a magic fix and maintained weight loss relies on combined behavioural management.
