Fresh analysis indicates that individuals who stop using new weight-loss injections like semaglutide or tirzepatide can put back on shed pounds far faster than those who halt traditional lifestyle programs.
Findings released in a major health publication points out that while overweight individuals frequently drop substantial amounts of their body weight while undergoing treatment, the weight comes back at an estimated rate of nearly a kilo each month upon discontinuation.
"People purchasing these drugs must be cognizant of the danger of rapid weight regain when the medication ends," stated lead investigator Dr. Susan Jebb.
Such speed of regain implies a reversion to original weight in about 18 months.
Weighing Approaches
The analysis, which looked at dozens of studies involving thousands of patients, contrasted the outcomes of the injectable medications with other pills.
The team emphasize that people who shed pounds through diet and exercise usually have a more gradual weight regain—around 100 grams monthly—once they finish.
The Reason for the Quick Regain
Doctors propose the way of the drugs explains the amplified rebound.
GLP-1 drugs copy a natural hormone called GLP-1, which moderates appetite.
"Sustained high doses of the hormone levels several times higher than the body's typical production could lead to the system to produce less of its endogenous GLP-1, and may also diminish sensitivity to its actions," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this hormone supplement means hunger is unsuppressed, making binge eating far more likely."
An Ongoing Disease?
Medical guidelines suggest the jabs for individuals with weight-linked medical conditions, alongside prescribed lifestyle changes.
Many experts say that, given the high risk of weight regain, the treatment might need to be ongoing.
This opinion is reinforced by pharmaceutical companies, who say that the findings "underscore the long-term character of excess weight," comparing it to managing conditions like diabetes.
Patient Accounts
Users who have stopped the medication describe a powerful return of hunger.
"It felt as if a switch flipping and you become extremely hungry," described an individual.
This difficulty is compounded if patients have not developed sustainable dietary or behavioural modifications during treatment.
Significant Use
Survey data suggest that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with desire remaining high.
- Adoption is more common among women compared to males.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion access the drugs through private prescriptions rather than public health services.
Ultimately, researchers stress that while these medications are potent tools for shedding pounds, they are not a magic fix and maintained weight loss relies on combined lifestyle changes.
