A recent study suggests that people who discontinue new GLP-1 drugs like Mounjaro or Wegovy can put back on reduced body mass far faster than those who halt traditional diet and exercise plans.
Findings released in a major health publication points out that while obese people often shed a large proportion of their total mass while undergoing treatment, the mass is regained at an average rate of nearly a kilo each month upon discontinuation.
"Individuals using such treatments must be aware of the danger of fast weight regain when the treatment ends," cautioned researcher Dr. Susan Jebb.
This pace of recovery means a reversion to original mass within about 18 months.
Analyzing Approaches
The analysis, which reviewed dozens of trials involving thousands of participants, compared the results of these new drugs with older methods.
The team emphasize that individuals who lose weight through diet and exercise usually experience a more gradual creep back—perhaps 100 grams monthly—post-intervention.
Explaining the Quick Regain
Experts suggest the mode of action of the injections accounts for the amplified rebound.
These medications mimic a natural hormone called glucagon-like peptide-1, which moderates appetite.
"Long-term administration of GLP-1 concentrations several times higher than the body's typical production may cause the system to generate a reduced amount of its endogenous hormone, and may also diminish responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this medication results in appetite is unsuppressed, making excessive eating much more probable."
A Chronic Issue?
Health authorities advise the injections for individuals with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
Professionals contend that, due to the high risk of relapse, the treatment is often life-long.
This opinion is reinforced by drug manufacturers, who note that the results "highlight the chronic character of excess weight," comparing it to managing conditions like diabetes.
Patient Testimonies
Individuals who have come off the medication describe a intense resurgence of cravings.
"It was like something activating and I was suddenly ravenous," said an individual.
This difficulty is worsened if individuals have not established lasting lifestyle or habit changes during treatment.
Significant Use
Survey data show that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with demand being substantial.
- Use is greater among females compared to males.
- The 40s and 50s age group shows the highest usage rates.
- Many access the medications through private healthcare rather than public health services.
In conclusion, researchers stress that while GLP-1 drugs are effective tools for shedding pounds, they are not a magic fix and maintained weight loss likely depends on ongoing lifestyle changes.
