New research indicates that individuals who come off popular weight-loss injections like semaglutide or tirzepatide may regain reduced body mass at a significantly accelerated pace than those who halt traditional diet and exercise regimens.
Research printed in a prominent health publication demonstrates that while obese people can lose substantial amounts of their body weight while undergoing treatment, the weight is regained at an average rate of 0.8 kg per month upon discontinuation.
"People buying such medications should be informed of the potential of quick weight regain when the medication is stopped," stated researcher Dr. Susan Jebb.
This pace of recovery suggests a return to pre-treatment weight in about 18 months.
Comparing Therapies
The study, which looked at dozens of studies involving over 9,000 of patients, compared the effects of GLP-1 agonists with older methods.
The team emphasize that people who lose weight through lifestyle changes alone typically have a less rapid weight regain—approximately 100 grams monthly—once they finish.
Explaining the Fast Regain
Nutrition scientists suggest the way of the injections explains the accelerated regain.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which controls hunger.
"Long-term administration of GLP-1 levels far above than the body's typical production may cause the body to produce less of its own natural GLP-1, and may also reduce sensitivity to its actions," said Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this GLP-1 'fix' leads to hunger is no longer kept in check, making binge eating far more likely."
A Lifelong Disease?
Health authorities suggest the jabs for people with weight-linked health risks, alongside recommended lifestyle changes.
Many experts argue that, given the high risk of weight regain, the treatment is often long-term.
This perspective is echoed by pharmaceutical companies, who state that the findings "highlight the chronic character of excess weight," akin to managing diseases like diabetes.
User Testimonies
Users who have come off the jabs describe a intense resurgence of hunger.
"It was like a trigger flipping and I was suddenly extremely hungry," said an individual.
This challenge is exacerbated if individuals have not adopted lasting lifestyle or habit modifications during therapy.
Growing Use
Recent estimates show that a significant number of people in the UK have tried weight-loss jabs in the past year, with interest continuing to grow.
- Adoption is greater among females than males.
- The middle-aged demographic shows the highest 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 effective tools for weight loss, they are not a permanent solution and lasting health benefits hinges on combined behavioural support.
