Fresh analysis reveals that people who come off popular weight-loss injections like semaglutide or tirzepatide tend to recover reduced body mass far faster than those who stop traditional diet and exercise regimens.
Findings released in a leading medical journal shows that while overweight people frequently drop about a fifth of their total mass while using the jabs, the mass is regained at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals purchasing such medications must be aware of the risk of rapid rebound weight gain when the medication is stopped," cautioned expert Dr. Susan Jebb.
This pace of regain suggests a reversion to starting mass within about a year and a half.
Comparing Treatments
The analysis, which looked at dozens of studies involving over 9,000 of participants, contrasted the results of the injectable medications with older methods.
The team note that people who shed pounds through lifestyle changes alone usually see a more gradual weight regain—approximately 0.1 kg a month—once they finish.
Understanding the Fast Regain
Experts propose the mode of action of the jabs accounts for the amplified regain.
These medications imitate a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Sustained high doses of GLP-1 levels several times higher than normal could lead to the body to produce less of its own natural hormone, and could diminish responsiveness to its effects," noted Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement leads to appetite is no longer kept in check, making overeating far more likely."
An Ongoing Disease?
Medical guidelines recommend the injections for individuals with obesity-related health risks, accompanied by prescribed lifestyle changes.
Many experts argue that, due to the significant potential of relapse, the therapy might need to be long-term.
This perspective is supported by pharmaceutical companies, who say that the findings "highlight the long-term nature of obesity," similar to managing diseases like diabetes.
User Experiences
Individuals who have discontinued the jabs describe a powerful resurgence of cravings.
"I experienced a trigger activating and you become starving," described an individual.
The struggle is compounded if users have not established sustainable dietary or behavioural modifications during treatment.
Growing Interest
Recent estimates indicate that millions of adults in the UK have tried weight-loss jabs in the past year, with interest being substantial.
- Use is higher among women than males.
- The middle-aged demographic shows the greatest usage rates.
- A large proportion access the medications through private healthcare rather than public health services.
In conclusion, researchers caution that while these medications are potent tools for shedding pounds, they are not a magic fix and lasting health benefits hinges on ongoing lifestyle changes.
