Users Coming Off Weight-Loss Injections Put On Pounds Four Times Faster Than People Using Diet and Exercise
New research reveals that patients who stop using blockbuster weight-loss injections like semaglutide or tirzepatide can put back on shed pounds far faster than those who end traditional lifestyle programs.
Published data in a major medical journal points out that while overweight people frequently drop about a fifth of their body weight while using the jabs, the weight is regained at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals using these treatments should be aware of the potential of fast rebound weight gain when the medication is stopped," cautioned expert Dr. Susan Jebb.
Such speed of recovery suggests a reversion to starting mass in about 18 months.
Weighing Approaches
The study, which reviewed 37 of trials involving thousands of participants, compared the effects of the injectable medications with older methods.
The team point out that people who shed pounds through dieting typically have a slower creep back—around 100 grams monthly—once they finish.
Understanding the Rapid Regain
Doctors propose the mode of action of the jabs explains the amplified regain.
These medications copy a natural hormone called glucagon-like peptide-1, which controls hunger.
"Artificially providing the hormone levels far above than normal could lead to the system to generate a reduced amount of its own natural hormone, and could reduce sensitivity to its effects," noted Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this GLP-1 'fix' leads to hunger is uncontrolled, making binge eating a significant risk."
A Chronic Issue?
Medical guidelines recommend the jabs for individuals with obesity-related health risks, alongside recommended diet and exercise modifications.
Professionals say that, given the significant potential of weight regain, the treatment is often life-long.
This view is reinforced by pharmaceutical companies, who say that the results "emphasize the persistent character of obesity," comparing it to managing diseases like diabetes.
User Testimonies
People who have stopped the medication explain a intense resurgence of cravings.
"It was like a trigger flipping and you become ravenous," described one woman.
This difficulty is worsened if individuals have not developed permanent dietary or behavioural changes during therapy.
Significant Use
Survey data suggest that a significant number of adults in the UK have tried these injections in the last 12 months, with demand continuing to grow.
- Use is more common among women compared to males.
- The middle-aged demographic shows the greatest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
Ultimately, clinicians caution that while these medications are effective agents for shedding pounds, they are not a standalone fix and maintained weight loss likely depends on ongoing lifestyle support.
