New research suggests that people who discontinue new slimming jabs like semaglutide or tirzepatide tend to recover reduced body mass at a significantly accelerated pace than those who halt conventional lifestyle regimens.
Findings released in a leading medical journal shows that while overweight people frequently drop about a fifth of their body weight while undergoing treatment, the mass comes back at an estimated rate of 0.8 kg per month upon discontinuation.
"Users buying such treatments should be informed of the potential of quick rebound weight gain when the medication ends," warns expert Dr. Susan Jebb.
This pace of recovery implies a return to starting mass in about a year and a half.
Analyzing Approaches
The study, which examined dozens of trials involving over 9,000 of patients, contrasted the effects of GLP-1 agonists with older methods.
Researchers emphasize that individuals who lose weight through lifestyle changes alone generally experience a more gradual weight regain—around 100 grams monthly—once they finish.
Explaining the Fast Rebound
Nutrition scientists believe the way of the jabs explains the accelerated regain.
These medications mimic a body's own chemical called GLP-1, which moderates appetite.
"Long-term administration of GLP-1 concentrations far above than the body's typical production could lead to the body to produce less of its own natural GLP-1, and may also diminish sensitivity to its actions," said Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this GLP-1 'fix' means hunger is uncontrolled, making excessive eating a significant risk."
A Chronic Disease?
Health authorities recommend the jabs for individuals with weight-linked medical conditions, alongside recommended lifestyle changes.
Many experts say that, considering the high risk of relapse, the therapy might need to be long-term.
This view is supported by drug manufacturers, who note that the findings "emphasize the long-term nature of obesity," akin to managing diseases like hypertension.
User Experiences
People who have discontinued the jabs describe a intense resurgence of appetite.
"I experienced a switch flipping and you're instantly ravenous," said an individual.
This difficulty is compounded if patients have not adopted permanent dietary or behavioural modifications during treatment.
Growing Interest
Recent estimates suggest that millions of people in the UK have used these injections in the last 12 months, with desire remaining high.
- Adoption is greater among females than males.
- The middle-aged demographic shows the highest usage rates.
- Many obtain the medications through private healthcare rather than public health services.
Finally, experts caution that while these medications are powerful tools for weight loss, they are not a magic solution and maintained weight loss relies on integrated lifestyle management.
