New research indicates that patients who come off blockbuster slimming jabs like semaglutide or tirzepatide can put back on reduced body mass much more quickly than those who halt traditional lifestyle regimens.
Published data in a leading medical journal points out that while overweight individuals often shed substantial amounts of their total mass while on the medication, the mass is regained at an average rate of nearly a kilo each month upon discontinuation.
"People buying these treatments need to be aware of the risk of quick weight regain when the therapy ends," stated expert Dr. Susan Jebb.
Such speed of regain implies a reversion to original weight in about one and a half years.
Analyzing Approaches
The analysis, which looked at 37 of studies involving thousands of participants, compared the results of the injectable medications with older methods.
Researchers point out that people who lose weight through diet and exercise generally experience a less rapid creep back—around 0.1 kg a month—post-intervention.
Understanding the Fast Regain
Nutrition scientists suggest the mode of action of the jabs explains the amplified regain.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.
"Sustained high doses of GLP-1 levels far above than the body's typical production may cause the system to produce less of its own natural hormone, and may also diminish responsiveness to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this hormone supplement leads to hunger is uncontrolled, making overeating a significant risk."
An Ongoing Condition?
The NHS recommend the injections for people with obesity-related medical conditions, alongside prescribed lifestyle changes.
A number of clinicians contend that, given the significant potential of relapse, the therapy might need to be long-term.
This perspective is supported by pharmaceutical companies, who state that the results "underscore the long-term character of excess weight," comparing it to managing conditions like high blood pressure.
User Testimonies
Users who have stopped the medication describe a powerful return of appetite.
"It felt as if something activating and you're instantly ravenous," described one woman.
This difficulty is compounded if users have not adopted lasting lifestyle or habit changes during treatment.
Growing Interest
Survey data show that a significant number of adults in the UK have used weight-loss jabs in the past year, with interest continuing to grow.
- Use is higher among females compared to males.
- The middle-aged demographic shows the greatest usage rates.
- A large proportion access the drugs through private healthcare rather than the NHS.
In conclusion, experts caution that while GLP-1 drugs are potent agents for weight loss, they are not a permanent cure and lasting health benefits likely depends on integrated behavioural management.
