Fresh analysis indicates that individuals who come off blockbuster weight-loss injections like Mounjaro or Wegovy tend to recover lost weight far faster than those who stop traditional diet and exercise plans.
Published data in a leading health publication shows that while overweight people can lose about a fifth of their body weight while on the medication, the mass comes back at an average rate of nearly a kilo each month once they quit.
"Users purchasing these drugs must be informed of the potential of fast rebound weight gain when the treatment ends," warns lead investigator Dr. Susan Jebb.
That rate of recovery suggests a reversion to original weight within about one and a half years.
Analyzing Treatments
The study, which looked at 37 of trials involving thousands of patients, compared the outcomes of the injectable medications with older methods.
Scientists point out that individuals who shed pounds through dieting usually experience a more gradual weight regain—around 100 grams monthly—once they finish.
Understanding the Fast Regain
Nutrition scientists believe the mode of action of the jabs accounts for the accelerated weight return.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which helps regulate hunger.
"Sustained high doses of the hormone levels far above than normal may cause the body to generate a reduced amount of its own natural GLP-1, and could diminish sensitivity to its actions," noted Dr. Adam Collins, a nutrition expert.
"Withdrawal of this hormone supplement leads to hunger is unsuppressed, making binge eating much more probable."
An Ongoing Disease?
The NHS suggest the injections for individuals with weight-linked medical conditions, accompanied by recommended lifestyle changes.
A number of clinicians say that, due to the high risk of relapse, the treatment is often ongoing.
This opinion is reinforced by drug manufacturers, who note that the findings "highlight the chronic character of obesity," similar to managing conditions like diabetes.
Patient Accounts
People who have discontinued the medication explain a sudden return of hunger.
"It felt as if a trigger that goes on and you become extremely hungry," said an individual.
The struggle is compounded if patients have not adopted lasting lifestyle or habit modifications during therapy.
Growing Interest
Survey data suggest that millions of people in the UK have used weight-loss jabs in the past year, with interest continuing to grow.
- Adoption is greater among females than males.
- The middle-aged age group shows the highest level of interest.
- Many access the medications through private prescriptions rather than the NHS.
In conclusion, researchers emphasize that while the jabs are potent agents for shedding pounds, they are not a magic fix and lasting health benefits likely depends on integrated behavioural changes.
