Fresh analysis indicates that people who come off blockbuster weight-loss injections like Wegovy and Mounjaro may regain shed pounds much more quickly than those who stop conventional lifestyle regimens.
Published data in a prominent medical journal demonstrates that while overweight people can lose about a fifth of their body weight while using the jabs, the mass returns at an estimated rate of 0.8 kg per month once they quit.
"Users purchasing these treatments must be informed of the danger of fast weight regain when the medication ends," cautioned expert Dr. Susan Jebb.
That rate of recovery implies a reversion to starting weight in about 18 months.
Analyzing Treatments
The research, which examined dozens of studies involving thousands of participants, compared the outcomes of these new drugs with conventional dieting.
Scientists point out that individuals who lose weight through lifestyle changes alone generally have a slower creep back—approximately 0.1 kg a month—post-intervention.
Understanding the Rapid Rebound
Experts believe the way of the injections explains the amplified weight return.
These medications copy a natural hormone called glucagon-like peptide-1, which moderates appetite.
"Sustained high doses of the hormone concentrations several times higher than normal might result in the body to generate a reduced amount of its endogenous GLP-1, and may also lessen sensitivity to its effects," noted Dr. Adam Collins, a dietetics expert.
"Withdrawal of this hormone supplement results in hunger is unsuppressed, making excessive eating a significant risk."
A Chronic Issue?
The NHS advise the injections for individuals with obesity-related medical conditions, alongside recommended lifestyle changes.
A number of clinicians say that, due to the high risk of relapse, the treatment is often long-term.
This opinion is supported by pharmaceutical companies, who say that the findings "underscore the persistent character of obesity," comparing it to managing conditions like hypertension.
User Testimonies
People who have stopped the jabs explain a intense resurgence of cravings.
"I experienced a trigger that goes on and I was suddenly extremely hungry," described a patient.
This challenge is worsened if patients have not established sustainable dietary or behavioural modifications during therapy.
Significant Use
Recent estimates show that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with interest being substantial.
- Use is higher among women compared to men.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
In conclusion, researchers stress that while the jabs are potent agents for weight loss, they are not a permanent fix and lasting health benefits hinges on integrated lifestyle support.
