A recent study suggests that patients who discontinue new weight-loss injections like semaglutide or tirzepatide may regain shed pounds far faster than those who halt traditional diet and exercise regimens.
Research printed in a prominent medical journal points out that while obese individuals frequently drop about a fifth of their total mass while undergoing treatment, the mass returns at an average rate of nearly a kilo each month upon discontinuation.
"Individuals using such treatments must be aware of the potential of quick rebound weight gain when the therapy ends," warns expert Dr. Susan Jebb.
This pace of recovery implies a reversion to pre-treatment weight within about one and a half years.
Comparing Treatments
The study, which reviewed dozens of studies involving thousands of participants, compared the results of these new drugs with conventional dieting.
Scientists note that individuals who shed pounds through lifestyle changes alone generally have a more gradual creep back—approximately 100 grams monthly—after stopping.
Understanding the Quick Regain
Doctors believe the way of the injections explains the heightened weight return.
GLP-1 drugs copy a body's own chemical called GLP-1, which controls appetite.
"Artificially providing GLP-1 levels several times higher than the body's typical production might result in the body to generate a reduced amount of its endogenous hormone, and could diminish responsiveness to its actions," noted Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement results in hunger is no longer kept in check, making binge eating far more likely."
An Ongoing Issue?
The NHS recommend the injections for people with weight-linked medical conditions, accompanied by recommended lifestyle changes.
Many experts argue that, considering the likelihood of weight regain, the treatment is often ongoing.
This opinion is reinforced by pharmaceutical companies, who say that the results "emphasize the persistent nature of obesity," similar to managing diseases like high blood pressure.
User Testimonies
Users who have come off the jabs describe a intense return of appetite.
"I experienced something that goes on and you're instantly starving," said an individual.
The struggle is exacerbated if individuals have not established lasting lifestyle or habit modifications during therapy.
Growing Interest
Recent estimates indicate that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with interest continuing to grow.
- Use is more common among women compared to men.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion obtain the medications through private healthcare rather than public health services.
In conclusion, clinicians stress that while the jabs are potent agents for weight loss, they are not a standalone cure and lasting health benefits likely depends on ongoing behavioural changes.
