New research reveals that people who stop using blockbuster weight-loss injections like semaglutide or tirzepatide may regain reduced body mass far faster than those who end conventional lifestyle programs.
Findings released in a prominent health publication shows that while obese people often shed substantial amounts of their body weight while using the jabs, the mass is regained at an average rate of 0.8 kg per month after stopping.
"People buying these drugs need to be cognizant of the potential of rapid rebound weight gain when the medication ends," cautioned expert Dr. Susan Jebb.
That rate of regain implies a return to starting mass in about a year and a half.
Weighing Treatments
The analysis, which looked at 37 of trials involving over 9,000 of patients, compared the outcomes of GLP-1 agonists with other pills.
Researchers emphasize that individuals who shed pounds through lifestyle changes alone typically see a slower weight regain—approximately 100 grams monthly—once they finish.
Explaining the Quick Regain
Experts suggest the mode of action of the jabs accounts for the amplified weight return.
GLP-1 drugs mimic a body's own chemical called GLP-1, which helps regulate appetite.
"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 hormone, and could lessen responsiveness to its effects," noted Dr. Adam Collins, a dietetics expert.
"Withdrawal of this hormone supplement means hunger is unsuppressed, making overeating a significant risk."
An Ongoing Disease?
Health authorities recommend the injections for individuals with weight-linked medical conditions, alongside recommended diet and exercise modifications.
A number of clinicians say that, given the significant potential of weight regain, the treatment might need to be ongoing.
This perspective is reinforced by drug manufacturers, who say that the results "emphasize the long-term nature of obesity," comparing it to managing conditions like diabetes.
User Experiences
Individuals who have stopped the jabs report a intense return of appetite.
"It was like a trigger that goes on and I was suddenly extremely hungry," described an individual.
This challenge is exacerbated if users have not developed lasting lifestyle or habit modifications during treatment.
Significant 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.
- Adoption is higher among women than men.
- The middle-aged age group shows the greatest usage rates.
- A large proportion access the drugs through private prescriptions rather than public health services.
Ultimately, experts stress that while GLP-1 drugs are powerful agents for shedding pounds, they are not a magic cure and lasting health benefits likely depends on ongoing lifestyle management.
