Fresh analysis indicates that patients who come off new weight-loss injections like Wegovy and Mounjaro tend to recover reduced body mass much more quickly than those who end conventional diet and exercise plans.
Findings released in a leading medical journal demonstrates that while overweight individuals can lose about a fifth of their body weight while on the medication, the mass comes back at an average rate of nearly a kilo each month upon discontinuation.
"Users purchasing these treatments should be aware of the danger of quick rebound weight gain when the therapy concludes," cautioned expert Dr. Susan Jebb.
Such speed of recovery implies a return to starting weight in about 18 months.
Comparing Therapies
The research, which examined 37 of trials involving over 9,000 of participants, contrasted the outcomes of the injectable medications with conventional dieting.
Scientists emphasize that individuals who lose weight through lifestyle changes alone generally see a more gradual creep back—around 0.1 kg a month—post-intervention.
Understanding the Rapid Rebound
Experts believe the way of the injections is key to understanding the heightened rebound.
The injections mimic a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of GLP-1 levels far above than normal might result in the body to produce less of its endogenous hormone, and could lessen sensitivity to its actions," explained Dr. Adam Collins, a dietetics expert.
"Stopping of this GLP-1 'fix' results in hunger is no longer kept in check, making overeating much more probable."
A Lifelong Condition?
Health authorities recommend the injections for individuals with obesity-related health risks, alongside prescribed lifestyle changes.
Many experts say that, considering the high risk of weight regain, the therapy should be considered life-long.
This view is supported by pharmaceutical companies, who state that the results "emphasize the long-term character of excess weight," akin to managing diseases like diabetes.
User Accounts
People who have come off the medication describe a sudden resurgence of hunger.
"It felt as if something activating and I was suddenly extremely hungry," described one woman.
This difficulty is exacerbated if patients have not developed permanent dietary or behavioural modifications during treatment.
Significant Adoption
Survey data indicate that a significant number of people in the UK have used weight-loss jabs in the past year, with interest being substantial.
- Adoption is greater among females compared to males.
- The 40s and 50s age group shows the highest level of interest.
- Many access the drugs through private healthcare rather than public health services.
In conclusion, experts emphasize that while the jabs are powerful tools for shedding pounds, they are not a permanent solution and long-term success relies on combined lifestyle changes.
