Fresh analysis reveals that people who discontinue new GLP-1 drugs like semaglutide or tirzepatide tend to recover lost weight far faster than those who stop conventional lifestyle programs.
Findings released in a leading health publication shows that while overweight people often shed 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 after stopping.
"People using such drugs need to be informed of the risk of rapid rebound weight gain when the therapy ends," cautioned researcher Dr. Susan Jebb.
This pace of recovery suggests a return to original mass in about 18 months.
Weighing Approaches
The research, which looked at dozens of trials involving thousands of participants, compared the outcomes of the injectable medications with other pills.
The team emphasize that individuals who shed pounds through lifestyle changes alone usually experience a slower weight regain—approximately 100 grams monthly—post-intervention.
The Reason for the Fast Regain
Doctors suggest the mechanism of the drugs accounts for the heightened rebound.
These medications imitate a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.
"Long-term administration of GLP-1 concentrations far above than the body's typical production could lead to the system to produce less of its own natural hormone, and may also reduce responsiveness to its actions," explained Dr. Adam Collins, a nutrition expert.
"Discontinuation of this medication leads to hunger is unsuppressed, making binge eating much more probable."
A Lifelong Condition?
Medical guidelines advise the injections for individuals with weight-linked health risks, accompanied by prescribed lifestyle changes.
Many experts argue that, considering the high risk of relapse, the treatment should be considered ongoing.
This perspective is echoed by drug manufacturers, who say that the results "emphasize the chronic nature of obesity," akin to managing diseases like hypertension.
User Testimonies
People who have stopped the jabs describe a intense resurgence of hunger.
"It was like a switch activating and I was suddenly starving," said an individual.
This difficulty is worsened if individuals have not established sustainable lifestyle or habit modifications during therapy.
Significant Interest
Survey data suggest that millions of people in the UK have tried weight-loss jabs in the last 12 months, with desire remaining high.
- Use is more common among females compared to men.
- The middle-aged age group shows the greatest level of interest.
- A large proportion access the drugs through private healthcare rather than public health services.
Ultimately, clinicians caution that while the jabs are powerful tools for shedding pounds, they are not a magic cure and lasting health benefits hinges on combined lifestyle support.
