New research suggests that people who come off new slimming jabs like semaglutide or tirzepatide may regain lost weight much more quickly than those who stop conventional lifestyle regimens.
Published data in a leading medical journal shows that while overweight people can lose substantial amounts of their body weight while undergoing treatment, the weight comes back at an estimated rate of 0.8 kg per month upon discontinuation.
"Individuals purchasing such medications need to be cognizant of the danger of rapid weight regain when the treatment is stopped," cautioned researcher Dr. Susan Jebb.
This pace of regain implies a reversion to original mass within about one and a half years.
Analyzing Approaches
The research, which reviewed dozens of studies involving over 9,000 of participants, contrasted the results of these new drugs with other pills.
The team emphasize that individuals who shed pounds through diet and exercise typically see a less rapid weight regain—perhaps 100 grams monthly—post-intervention.
Explaining the Fast Regain
Doctors believe the mode of action of the jabs is key to understanding the amplified regain.
The injections copy a natural hormone called GLP-1, which helps regulate hunger.
"Long-term administration of the hormone levels far above than the body's typical production could lead to the body to produce less of its endogenous GLP-1, and could diminish responsiveness to its actions," said Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this hormone supplement leads to hunger is no longer kept in check, making excessive eating much more probable."
A Chronic Disease?
The NHS suggest the jabs for people with weight-linked health risks, alongside prescribed diet and exercise modifications.
Professionals argue that, given the high risk of weight regain, the therapy is often life-long.
This opinion is echoed by drug manufacturers, who say that the findings "emphasize the chronic nature of excess weight," similar to managing conditions like diabetes.
Patient Experiences
Users who have stopped the medication describe a sudden return of cravings.
"I experienced a switch that goes on and I was suddenly ravenous," said a patient.
This difficulty is worsened if patients have not developed lasting lifestyle or habit modifications during treatment.
Growing Adoption
Recent estimates suggest that a significant number of people in the UK have tried these injections in the last 12 months, with interest being substantial.
- Adoption is greater among women than men.
- The middle-aged age group shows the greatest level of interest.
- A large proportion obtain the drugs through private healthcare rather than public health services.
In conclusion, clinicians emphasize that while these medications are effective agents for shedding pounds, they are not a standalone solution and lasting health benefits hinges on ongoing behavioural management.
