New research indicates that patients who stop using new weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds much more quickly than those who halt traditional diet and exercise regimens.
Research printed in a leading health publication shows that while obese individuals can lose substantial amounts of their body weight while using the jabs, the mass is regained at an average rate of 0.8 kg per month once they quit.
"Users purchasing such treatments should be aware of the potential of fast rebound weight gain when the therapy ends," warns expert Dr. Susan Jebb.
That rate of recovery implies a reversion to starting weight within about 18 months.
Comparing Approaches
The research, which examined 37 of trials involving thousands of patients, compared the outcomes of the injectable medications with conventional dieting.
The team emphasize that people who lose weight through diet and exercise generally see a more gradual weight regain—perhaps 0.1 kg a month—post-intervention.
The Reason for the Quick Rebound
Nutrition scientists believe the mechanism of the injections explains the amplified regain.
GLP-1 drugs imitate a natural hormone called GLP-1, which helps regulate hunger.
"Artificially providing GLP-1 levels far above than normal might result in the body to produce less of its endogenous hormone, and could reduce responsiveness to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this medication leads to hunger is no longer kept in check, making excessive eating much more probable."
A Chronic Disease?
Medical guidelines advise the injections for individuals with weight-linked health risks, alongside recommended lifestyle changes.
Many experts contend that, due to the likelihood of relapse, the therapy is often life-long.
This opinion is supported by drug manufacturers, who state that the findings "underscore the chronic character of excess weight," akin to managing diseases like diabetes.
User Testimonies
People who have stopped the medication describe a intense resurgence of hunger.
"It felt as if a trigger activating and you become ravenous," recalled one woman.
This difficulty is compounded if users have not adopted sustainable lifestyle or habit changes during treatment.
Growing Use
Recent estimates show that a significant number of adults in the UK have used weight-loss jabs in the last 12 months, with demand being substantial.
- Adoption is higher among women compared to males.
- The middle-aged age group shows the highest usage rates.
- A large proportion access the drugs through private healthcare rather than public health services.
In conclusion, experts emphasize that while these medications are potent tools for weight loss, they are not a standalone fix and long-term success likely depends on integrated behavioural management.
