New research suggests that people who stop using popular GLP-1 drugs like semaglutide or tirzepatide can put back on reduced body mass far faster than those who end traditional diet and exercise plans.
Published data in a leading medical journal points out that while overweight individuals can lose a large proportion of their body weight while undergoing treatment, the mass comes back at an average rate of nearly a kilo each month upon discontinuation.
"People purchasing such drugs must be aware of the danger of fast weight regain when the treatment concludes," cautioned researcher Dr. Susan Jebb.
Such speed of regain suggests a reversion to starting weight in about a year and a half.
Weighing Therapies
The analysis, which looked at 37 of studies involving over 9,000 of patients, compared the outcomes of the injectable medications with other pills.
The team note that individuals who shed pounds through lifestyle changes alone usually see a more gradual creep back—perhaps 100 grams monthly—after stopping.
Understanding the Fast Rebound
Doctors believe the way of the drugs accounts for the heightened weight return.
These medications mimic a body's own chemical called glucagon-like peptide-1, which controls appetite.
"Sustained high doses of GLP-1 concentrations several times higher than normal may cause the body to produce less of its own natural hormone, and may also lessen sensitivity to its actions," explained Dr. Adam Collins, a nutrition researcher.
"Stopping of this hormone supplement results in hunger is uncontrolled, making excessive eating a significant risk."
A Chronic Issue?
Medical guidelines advise the injections for individuals with weight-linked medical conditions, accompanied by recommended lifestyle changes.
Professionals contend that, due to the likelihood of relapse, the treatment is often life-long.
This opinion is reinforced by pharmaceutical companies, who say that the findings "underscore the chronic nature of obesity," akin to managing diseases like diabetes.
User Testimonies
Users who have come off the medication describe a sudden return of appetite.
"It was like a switch that goes on and you're instantly extremely hungry," said a patient.
The struggle is compounded if patients have not adopted sustainable lifestyle or habit modifications during therapy.
Significant Adoption
Recent estimates show that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with desire continuing to grow.
- Use is greater among females than males.
- The 40s and 50s age group shows the highest level of interest.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
In conclusion, experts stress that while the jabs are powerful agents for shedding pounds, they are not a standalone cure and long-term success hinges on integrated lifestyle support.
