New research indicates that individuals who come off new weight-loss injections like Mounjaro or Wegovy can put back on shed pounds far faster than those who halt traditional diet and exercise programs.
Published data in a leading health publication points out that while overweight people frequently drop a large proportion of their total mass while undergoing treatment, the mass comes back at an average rate of nearly a kilo each month once they quit.
"Users buying these medications should be aware of the danger of quick rebound weight gain when the treatment concludes," cautioned lead investigator Dr. Susan Jebb.
This pace of regain suggests a reversion to original mass in about a year and a half.
Analyzing Approaches
The analysis, which examined dozens of studies involving thousands of participants, compared the results of GLP-1 agonists with other pills.
The team emphasize that individuals who lose weight through diet and exercise usually experience a more gradual creep back—around 100 grams monthly—once they finish.
The Reason for the Rapid Regain
Experts suggest the mechanism of the drugs accounts for the amplified regain.
These medications imitate a natural hormone called GLP-1, which controls appetite.
"Artificially providing GLP-1 levels far above than normal might result in the system to generate a reduced amount of its own natural GLP-1, and may also diminish responsiveness to its actions," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this hormone supplement results in appetite is uncontrolled, making overeating much more probable."
An Ongoing Condition?
The NHS suggest the jabs for individuals with weight-linked medical conditions, alongside prescribed lifestyle changes.
A number of clinicians say that, considering the significant potential of weight regain, the treatment might need to be long-term.
This perspective is echoed by pharmaceutical companies, who say that the results "highlight the persistent nature of obesity," comparing it to managing conditions like hypertension.
Patient Accounts
Users who have come off the medication explain a sudden resurgence of cravings.
"I experienced a trigger flipping and I was suddenly ravenous," described an individual.
This difficulty is worsened if patients have not adopted sustainable lifestyle or habit modifications during treatment.
Significant Interest
Survey data indicate that millions of adults in the UK have used these injections in the last 12 months, with interest remaining high.
- Use is more common among females than men.
- The middle-aged demographic shows the highest usage rates.
- Many access the medications through private prescriptions rather than the NHS.
In conclusion, researchers stress that while the jabs are effective agents for weight loss, they are not a permanent cure and maintained weight loss hinges on integrated behavioural management.
