New research indicates that people who stop using popular slimming jabs like Mounjaro or Wegovy tend to recover shed pounds far faster than those who end conventional diet and exercise programs.
Research printed in a prominent health publication points out that while overweight people frequently drop a large proportion of their body weight while on the medication, the weight is regained at an estimated rate of nearly a kilo each month after stopping.
"Users purchasing such medications should be informed of the danger of rapid rebound weight gain when the medication concludes," cautioned lead investigator Dr. Susan Jebb.
That rate of regain suggests a return to original weight in about a year and a half.
Analyzing Therapies
The study, which looked at 37 of trials involving over 9,000 of participants, compared the outcomes of the injectable medications with other pills.
Scientists emphasize that individuals who shed pounds through lifestyle changes alone typically experience a less rapid creep back—perhaps 0.1 kg a month—once they finish.
Understanding the Quick Regain
Doctors believe the way of the jabs accounts for the heightened rebound.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which moderates feelings of fullness.
"Artificially providing the hormone concentrations far above than the body's typical production could lead to the system to generate a reduced amount of its own natural GLP-1, and could lessen sensitivity to its effects," noted Dr. Adam Collins, a nutrition specialist.
"Stopping of this medication results in hunger is no longer kept in check, making overeating a significant risk."
A Lifelong Issue?
The NHS advise the jabs for people with obesity-related health risks, accompanied by recommended diet and exercise modifications.
A number of clinicians say that, due to the likelihood of weight regain, the therapy is often long-term.
This opinion is echoed by drug manufacturers, who note that the results "underscore the chronic nature of excess weight," comparing it to managing diseases like diabetes.
Patient Experiences
Individuals who have stopped the jabs describe a intense return of hunger.
"I experienced a switch flipping and you're instantly extremely hungry," said a patient.
This difficulty is compounded if individuals have not adopted sustainable dietary or behavioural modifications during therapy.
Significant Interest
Recent estimates suggest that millions of people in the UK have tried these injections in the last 12 months, with demand being substantial.
- Adoption is greater among women than men.
- The middle-aged demographic shows the highest usage rates.
- A large proportion access the drugs through private healthcare rather than the NHS.
Ultimately, researchers caution that while GLP-1 drugs are powerful agents for shedding pounds, they are not a magic cure and lasting health benefits hinges on combined behavioural changes.
