A recent study reveals that people who come off new slimming jabs like Mounjaro or Wegovy may regain reduced body mass at a significantly accelerated pace than those who halt traditional diet and exercise regimens.
Research printed in a leading health publication demonstrates that while overweight people can lose substantial amounts of their body weight while undergoing treatment, the mass is regained at an average rate of nearly a kilo each month after stopping.
"Users buying these medications should be aware of the potential of fast rebound weight gain when the therapy ends," cautioned expert Dr. Susan Jebb.
That rate of regain suggests a return to pre-treatment mass in about 18 months.
Weighing Approaches
The study, which examined 37 of trials involving over 9,000 of participants, compared the effects of the injectable medications with older methods.
Scientists point out that people who lose weight through lifestyle changes alone typically experience a slower weight regain—perhaps 100 grams monthly—after stopping.
Understanding the Quick Rebound
Experts believe the mode of action of the drugs is key to understanding the accelerated regain.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which controls feelings of fullness.
"Sustained high doses of GLP-1 concentrations far above than the body's typical production might result in the system to produce less of its endogenous GLP-1, and may also diminish responsiveness to its effects," noted Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this hormone supplement means appetite is uncontrolled, making excessive eating far more likely."
A Lifelong Issue?
Medical guidelines suggest the injections for individuals with obesity-related health risks, accompanied by recommended lifestyle changes.
A number of clinicians argue that, considering the likelihood of relapse, the treatment should be considered ongoing.
This opinion is reinforced by drug manufacturers, who say that the results "underscore the chronic character of obesity," similar to managing diseases like high blood pressure.
User Testimonies
People who have stopped the jabs report a sudden return of appetite.
"I experienced a trigger that goes on and I was suddenly extremely hungry," said one woman.
The struggle is compounded if users have not adopted lasting lifestyle or habit modifications during treatment.
Widespread Use
Recent estimates indicate that a significant number of people in the UK have used these injections in the past year, with interest being substantial.
- Use is greater among women than males.
- The middle-aged age group shows the highest level of interest.
- Many access the medications through private healthcare rather than the NHS.
In conclusion, researchers caution that while these medications are powerful tools for weight loss, they are not a standalone solution and lasting health benefits hinges on ongoing lifestyle changes.
