A recent study reveals that patients who come off new weight-loss injections like Mounjaro or Wegovy may regain reduced body mass far faster than those who halt traditional diet and exercise regimens.
Published data in a leading health publication shows that while overweight individuals frequently drop about a fifth of their total mass while undergoing treatment, the weight comes back at an estimated rate of nearly a kilo each month once they quit.
"Individuals buying such treatments must be aware of the risk of fast weight regain when the therapy ends," cautioned researcher Dr. Susan Jebb.
Such speed of regain implies a return to original weight within about 18 months.
Analyzing Therapies
The analysis, which reviewed dozens of studies involving over 9,000 of participants, contrasted the effects of the injectable medications with conventional dieting.
Scientists point out that individuals who shed pounds through diet and exercise typically experience a more gradual creep back—perhaps 0.1 kg a month—after stopping.
The Reason for the Quick Rebound
Nutrition scientists believe the mode of action of the injections accounts for the accelerated regain.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of the hormone concentrations far above than normal could lead to the system to generate a reduced amount of its own natural GLP-1, and could reduce sensitivity to its actions," noted Dr. Adam Collins, a dietetics specialist.
"Stopping of this medication leads to hunger is uncontrolled, making excessive eating far more likely."
A Chronic Disease?
The NHS advise the injections for individuals with weight-linked health risks, alongside prescribed diet and exercise modifications.
Many experts contend that, due to the likelihood of relapse, the treatment should be considered long-term.
This view is reinforced by pharmaceutical companies, who state that the findings "highlight the long-term character of obesity," comparing it to managing diseases like diabetes.
Patient Testimonies
People who have stopped the medication explain a intense return of appetite.
"I experienced a trigger that goes on and I was suddenly starving," recalled one woman.
This challenge is exacerbated if individuals have not established lasting lifestyle or habit modifications during therapy.
Significant Interest
Survey data suggest that a significant number of adults in the UK have used weight-loss jabs in the last 12 months, with demand being substantial.
- Use is greater among women than males.
- The middle-aged age group shows the highest usage rates.
- Many obtain the drugs through private prescriptions rather than the NHS.
In conclusion, researchers emphasize that while GLP-1 drugs are powerful agents for weight loss, they are not a magic cure and maintained weight loss hinges on integrated behavioural changes.
