Fresh analysis suggests that patients who come off blockbuster slimming jabs like semaglutide or tirzepatide may regain shed pounds at a significantly accelerated pace than those who stop traditional lifestyle programs.
Findings released in a major medical journal demonstrates that while obese people can lose substantial amounts of their body weight while on the medication, the weight is regained at an average rate of 0.8 kg per month once they quit.
"People buying these medications must be cognizant of the potential of quick weight regain when the treatment concludes," stated researcher Dr. Susan Jebb.
Such speed of regain suggests a reversion to original mass in about one and a half years.
Weighing Approaches
The analysis, which looked at 37 of studies involving over 9,000 of participants, compared the effects of the injectable medications with conventional dieting.
The team point out that people who lose weight through dieting typically experience a more gradual weight regain—approximately 0.1 kg a month—once they finish.
Understanding the Quick Regain
Nutrition scientists propose the mode of action of the injections accounts for the amplified rebound.
The injections mimic a natural hormone called GLP-1, which controls appetite.
"Sustained high doses of the hormone concentrations far above than the body's typical production could lead to the body to produce less of its own natural GLP-1, and may also reduce responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this hormone supplement results in hunger is unsuppressed, making excessive eating much more probable."
A Chronic Issue?
Health authorities recommend the injections for individuals with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
Many experts say that, given the likelihood of relapse, the treatment is often life-long.
This perspective is reinforced by drug manufacturers, who say that the results "emphasize the long-term nature of excess weight," similar to managing diseases like diabetes.
Patient Experiences
Individuals who have stopped the medication explain a powerful return of cravings.
"It felt as if a trigger that goes on and you're instantly starving," described an individual.
The struggle is compounded if patients have not developed permanent dietary or behavioural modifications during treatment.
Widespread Use
Survey data suggest that a significant number of people in the UK have used these injections in the last 12 months, with desire being substantial.
- Use is greater among females than men.
- The middle-aged demographic shows the highest usage rates.
- A large proportion access the drugs through private healthcare rather than public health services.
Finally, clinicians emphasize that while GLP-1 drugs are effective agents for shedding pounds, they are not a permanent cure and lasting health benefits relies on ongoing lifestyle changes.
