Fresh analysis reveals that people who stop using popular weight-loss injections like semaglutide or tirzepatide tend to recover lost weight far faster than those who stop conventional lifestyle plans.
Findings released in a major medical journal points out that while obese people can lose substantial amounts of their body weight while undergoing treatment, the mass is regained at an average rate of nearly a kilo each month upon discontinuation.
"People purchasing these treatments must be aware of the danger of quick weight regain when the treatment ends," warns expert Dr. Susan Jebb.
This pace of regain suggests a reversion to original weight in about 18 months.
Weighing Therapies
The study, which reviewed 37 of studies involving thousands of patients, contrasted the results of these new drugs with other pills.
Researchers point out that individuals who lose weight through dieting generally see a less rapid creep back—around 100 grams monthly—after stopping.
Understanding the Quick Rebound
Nutrition scientists believe the mechanism of the injections accounts for the amplified weight return.
GLP-1 drugs copy a body's own chemical called glucagon-like peptide-1, which controls appetite.
"Long-term administration of GLP-1 concentrations far above than the body's typical production may cause the body to generate a reduced amount of its endogenous GLP-1, and may also diminish responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this medication leads to hunger is no longer kept in check, making overeating a significant risk."
An Ongoing Condition?
The NHS recommend the jabs for people with weight-linked health risks, alongside recommended diet and exercise modifications.
A number of clinicians say that, given the likelihood of relapse, the therapy is often long-term.
This opinion is supported by pharmaceutical companies, who say that the findings "highlight the persistent nature of excess weight," similar to managing conditions like diabetes.
Patient Testimonies
People who have stopped the medication report a intense resurgence of appetite.
"It was like a switch activating and you're instantly ravenous," said one woman.
This difficulty is compounded if individuals have not developed sustainable dietary or behavioural modifications during treatment.
Growing Interest
Survey data show that a significant number of people in the UK have tried weight-loss jabs in the past year, with demand remaining high.
- Adoption is greater among women compared to men.
- The middle-aged demographic shows the highest usage rates.
- Many access the drugs through private healthcare rather than public health services.
In conclusion, experts emphasize that while these medications are effective agents for shedding pounds, they are not a magic solution and lasting health benefits relies on ongoing lifestyle changes.
