A recent study suggests that people who come off popular weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds at a significantly accelerated pace than those who end traditional lifestyle programs.
Findings released in a leading medical journal shows that while obese people can lose substantial amounts of their total mass while using the jabs, the weight is regained at an estimated rate of 0.8 kg per month once they quit.
"Individuals purchasing these treatments should be cognizant of the risk of quick weight regain when the treatment ends," stated lead investigator Dr. Susan Jebb.
This pace of regain suggests a reversion to starting weight in about a year and a half.
Analyzing Treatments
The study, which examined dozens of studies involving over 9,000 of patients, compared the effects of these new drugs with other pills.
Scientists point out that people who lose weight through diet and exercise generally have a less rapid weight regain—approximately 100 grams monthly—post-intervention.
The Reason for the Fast Regain
Experts suggest the way of the injections accounts for the heightened weight return.
The injections copy a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Artificially providing the hormone concentrations several times higher than normal could lead to the system to generate a reduced amount of its endogenous hormone, and may also diminish sensitivity to its effects," said Dr. Adam Collins, a nutrition expert.
"Withdrawal of this GLP-1 'fix' results in hunger is uncontrolled, making overeating a significant risk."
A Lifelong Issue?
Medical guidelines recommend the jabs for individuals with obesity-related health risks, alongside prescribed diet and exercise modifications.
Professionals contend that, given the significant potential of relapse, the therapy is often life-long.
This opinion is reinforced by pharmaceutical companies, who note that the findings "underscore the chronic nature of obesity," akin to managing conditions like hypertension.
User Accounts
Individuals who have discontinued the medication describe a sudden resurgence of cravings.
"It was like a switch activating and you become ravenous," described a patient.
This difficulty is worsened if users have not adopted sustainable lifestyle or habit modifications during treatment.
Widespread Adoption
Figures suggest that a significant number of adults in the UK have used weight-loss jabs in the past year, with demand remaining high.
- Adoption is higher among women compared to males.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the medications through private healthcare rather than public health services.
In conclusion, clinicians caution that while these medications are powerful agents for shedding pounds, they are not a standalone cure and maintained weight loss relies on ongoing behavioural management.
