A recent study indicates that patients who stop using blockbuster weight-loss injections like Mounjaro or Wegovy tend to recover lost weight much more quickly than those who end traditional diet and exercise regimens.
Published data in a leading medical journal demonstrates that while obese people can lose about a fifth of their body weight while undergoing treatment, the weight returns at an average rate of 0.8 kg per month after stopping.
"Individuals buying these drugs must be informed of the potential of quick rebound weight gain when the treatment is stopped," warns expert Dr. Susan Jebb.
Such speed of regain implies a reversion to pre-treatment mass within about a year and a half.
Comparing Therapies
The study, which looked at dozens of studies involving thousands of participants, contrasted the results of these new drugs with older methods.
The team note that individuals who shed pounds through lifestyle changes alone usually see a more gradual creep back—perhaps 100 grams monthly—after stopping.
Understanding the Fast Rebound
Doctors propose the way of the injections explains the accelerated rebound.
GLP-1 drugs copy a natural hormone called GLP-1, which controls hunger.
"Artificially providing the hormone concentrations far above than the body's typical production could lead to the body to generate a reduced amount of its own natural hormone, and may also reduce sensitivity to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this medication leads to hunger is uncontrolled, making excessive eating a significant risk."
A Lifelong Condition?
Health authorities suggest the jabs for people with obesity-related medical conditions, alongside recommended diet and exercise modifications.
Professionals say that, due to the significant potential of weight regain, the treatment should be considered long-term.
This view is echoed by pharmaceutical companies, who note that the results "highlight the persistent nature of excess weight," akin to managing diseases like hypertension.
User Testimonies
Individuals who have come off the medication report a intense resurgence of cravings.
"It felt as if something that goes on and you become ravenous," described a patient.
This challenge is worsened if patients have not developed permanent lifestyle or habit changes during therapy.
Significant Use
Recent estimates show that a significant number of people in the UK have used weight-loss jabs in the past year, with interest continuing to grow.
- Use is higher among women than males.
- The 40s and 50s age group shows the highest usage rates.
- Many access the medications through private prescriptions rather than public health services.
In conclusion, researchers stress that while GLP-1 drugs are potent tools for weight loss, they are not a standalone fix and long-term success relies on ongoing lifestyle support.
