A recent study suggests that individuals who come off new GLP-1 drugs like Wegovy and Mounjaro can put back on shed pounds far faster than those who halt conventional diet and exercise programs.
Findings released in a major health publication shows that while obese individuals can lose a large proportion of their body weight while on the medication, the weight returns at an average rate of 0.8 kg per month upon discontinuation.
"Individuals purchasing these drugs should be informed of the risk of fast rebound weight gain when the therapy concludes," cautioned expert Dr. Susan Jebb.
This pace of recovery means a return to starting mass within about a year and a half.
Comparing Treatments
The research, which examined 37 of trials involving thousands of patients, contrasted the outcomes of the injectable medications with conventional dieting.
The team note that people who shed pounds through diet and exercise usually have a less rapid creep back—around 100 grams monthly—once they finish.
Understanding the Quick Rebound
Experts suggest the mechanism of the injections explains the accelerated weight return.
These medications mimic a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of the hormone levels several times higher than the body's typical production might result in the body to produce less of its endogenous hormone, and may also reduce sensitivity to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this GLP-1 'fix' means hunger is uncontrolled, making binge eating far more likely."
A Chronic Issue?
Health authorities suggest the jabs for people with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
A number of clinicians argue that, due to the likelihood of relapse, the treatment is often long-term.
This view is reinforced by pharmaceutical companies, who say that the results "emphasize the persistent nature of obesity," comparing it to managing diseases like high blood pressure.
User Accounts
People who have stopped the medication describe a sudden resurgence of appetite.
"I experienced a trigger activating and you become ravenous," said one woman.
The struggle is compounded if patients have not established sustainable lifestyle or habit modifications during therapy.
Widespread Interest
Survey data suggest that millions of people in the UK have tried weight-loss jabs in the last 12 months, with demand remaining high.
- Use is higher among women than males.
- The 40s and 50s demographic shows the highest level of interest.
- Many obtain the drugs through private prescriptions rather than public health services.
In conclusion, researchers stress that while these medications are effective agents for weight loss, they are not a magic cure and maintained weight loss hinges on ongoing lifestyle changes.
