Fresh analysis reveals that individuals who come off new GLP-1 drugs like semaglutide or tirzepatide tend to recover lost weight at a significantly accelerated pace than those who halt traditional lifestyle programs.
Research printed in a major medical journal points out that while obese people frequently drop substantial amounts of their total mass while using the jabs, the mass comes back at an estimated rate of nearly a kilo each month after stopping.
"Users using such drugs must be aware of the risk of rapid weight regain when the therapy concludes," cautioned expert Dr. Susan Jebb.
This pace of recovery implies a reversion to starting mass within about one and a half years.
Weighing Therapies
The study, which looked at 37 of trials involving over 9,000 of patients, contrasted the results of these new drugs with conventional dieting.
Researchers point out that individuals who lose weight through lifestyle changes alone typically see a slower weight regain—approximately 0.1 kg a month—after stopping.
Explaining the Fast Regain
Experts believe the mechanism of the injections accounts for the amplified rebound.
These medications copy a body's own chemical called GLP-1, which helps regulate hunger.
"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 own natural GLP-1, and may also lessen responsiveness to its actions," said Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement leads to hunger is uncontrolled, making binge eating much more probable."
A Lifelong Condition?
The NHS recommend the jabs for people with weight-linked health risks, accompanied by recommended diet and exercise modifications.
Many experts say that, given the likelihood of relapse, the therapy should be considered long-term.
This view is supported by pharmaceutical companies, who say that the results "emphasize the long-term nature of obesity," comparing it to managing conditions like hypertension.
Patient Experiences
Individuals who have come off the medication explain a powerful resurgence of appetite.
"It felt as if a trigger flipping and you're instantly extremely hungry," recalled an individual.
This difficulty is compounded if patients have not developed lasting lifestyle or habit modifications during therapy.
Significant Interest
Survey data indicate that millions of people in the UK have tried weight-loss jabs in the past year, with demand continuing to grow.
- Use is higher among women compared to males.
- The 40s and 50s demographic shows the highest level of interest.
- Many access the drugs through private prescriptions rather than the NHS.
In conclusion, experts caution that while GLP-1 drugs are potent tools for shedding pounds, they are not a permanent cure and lasting health benefits relies on ongoing lifestyle changes.
