A recent study suggests that patients who come off popular weight-loss injections like semaglutide or tirzepatide tend to recover reduced body mass far faster than those who halt traditional lifestyle regimens.
Research printed in a major medical journal demonstrates that while obese individuals frequently drop substantial amounts of their total mass while using the jabs, the weight is regained at an average rate of 0.8 kg per month after stopping.
"People using such drugs need to be cognizant of the danger of rapid weight regain when the medication concludes," cautioned researcher Dr. Susan Jebb.
That rate of recovery means a reversion to pre-treatment weight within about a year and a half.
Analyzing Therapies
The research, which examined 37 of trials involving thousands of patients, contrasted the effects of the injectable medications with other pills.
The team note that people who lose weight through dieting usually have a more gradual creep back—approximately 0.1 kg a month—once they finish.
The Reason for the Fast Rebound
Experts propose the mechanism of the drugs is key to understanding the accelerated regain.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.
"Artificially providing the hormone levels several times higher than normal might result in the system to generate a reduced amount of its own natural hormone, and could reduce sensitivity to its actions," explained Dr. Adam Collins, a nutrition expert.
"Stopping of this hormone supplement results in hunger is no longer kept in check, making excessive eating much more probable."
A Lifelong Issue?
The NHS recommend the injections for people with weight-linked health risks, accompanied by recommended lifestyle changes.
Professionals contend that, given the high risk of relapse, the therapy should be considered ongoing.
This view is reinforced by pharmaceutical companies, who say that the results "highlight the persistent nature of excess weight," akin to managing diseases like diabetes.
User Testimonies
Individuals who have discontinued the jabs explain a powerful return of hunger.
"I experienced a trigger flipping and you become ravenous," recalled one woman.
This difficulty is exacerbated if users have not established lasting lifestyle or habit modifications during treatment.
Widespread Adoption
Figures suggest that millions of people in the UK have used weight-loss jabs in the last 12 months, with demand continuing to grow.
- Use is higher among women than males.
- The middle-aged age group shows the highest usage rates.
- A large proportion access the drugs through private prescriptions rather than public health services.
Finally, clinicians stress that while the jabs are powerful tools for shedding pounds, they are not a magic solution and maintained weight loss likely depends on ongoing behavioural changes.
