Fresh analysis indicates that people who stop using new slimming jabs like Mounjaro or Wegovy can put back on shed pounds at a significantly accelerated pace than those who end conventional diet and exercise regimens.
Published data in a major medical journal demonstrates that while obese individuals can lose about a fifth of their body weight while undergoing treatment, the weight is regained at an average rate of nearly a kilo each month once they quit.
"Individuals buying these drugs should be aware of the danger of fast weight regain when the medication concludes," stated expert Dr. Susan Jebb.
Such speed of recovery implies a reversion to pre-treatment weight in about a year and a half.
Comparing Treatments
The analysis, which looked at 37 of trials involving over 9,000 of patients, contrasted the effects of these new drugs with other pills.
Scientists emphasize that people who lose weight through lifestyle changes alone typically have a less rapid creep back—perhaps 100 grams monthly—once they finish.
Explaining the Fast Regain
Experts propose the way of the drugs is key to understanding the heightened regain.
GLP-1 drugs imitate a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Artificially providing the hormone levels far above than the body's typical production may cause the system to produce less of its endogenous hormone, and could reduce responsiveness to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this GLP-1 'fix' results in appetite is no longer kept in check, making overeating far more likely."
An Ongoing Issue?
Health authorities advise the jabs for people with obesity-related medical conditions, accompanied by recommended lifestyle changes.
A number of clinicians contend that, due to the high risk of weight regain, the treatment should be considered ongoing.
This perspective is echoed by pharmaceutical companies, who note that the findings "highlight the chronic character of excess weight," comparing it to managing diseases like diabetes.
Patient Experiences
People who have discontinued the medication explain a powerful return of appetite.
"It felt as if something flipping and I was suddenly starving," described an individual.
This difficulty is compounded if users have not established lasting dietary or behavioural modifications during therapy.
Significant Interest
Survey data indicate that millions of adults in the UK have used weight-loss jabs in the last 12 months, with interest remaining high.
- Adoption is more common among females compared to males.
- The 40s and 50s age group shows the greatest level of interest.
- Many access the drugs through private prescriptions rather than public health services.
In conclusion, experts emphasize that while these medications are powerful tools for weight loss, they are not a standalone fix and lasting health benefits likely depends on ongoing lifestyle changes.
