New research reveals that patients who stop using popular weight-loss injections like Mounjaro or Wegovy can put back on lost weight much more quickly than those who end traditional lifestyle regimens.
Findings released in a prominent medical journal demonstrates that while overweight individuals can lose about a fifth of their body weight while undergoing treatment, the weight returns at an average rate of nearly a kilo each month upon discontinuation.
"People using such drugs must be informed of the risk of fast weight regain when the treatment is stopped," cautioned lead investigator Dr. Susan Jebb.
Such speed of regain suggests a return to original weight within about a year and a half.
Comparing Therapies
The analysis, which reviewed dozens of trials involving thousands of participants, contrasted the outcomes of these new drugs with conventional dieting.
The team note that individuals who shed pounds through lifestyle changes alone usually experience a more gradual weight regain—around 100 grams monthly—post-intervention.
Understanding the Rapid Regain
Experts suggest the way of the injections explains the heightened weight return.
GLP-1 drugs copy a body's own chemical called glucagon-like peptide-1, which helps regulate hunger.
"Sustained high doses of the hormone concentrations far above than the body's typical production might result in the body to generate a reduced amount of its own natural GLP-1, and may also lessen sensitivity to its actions," explained Dr. Adam Collins, a nutrition expert.
"Withdrawal of this GLP-1 'fix' results in appetite is unsuppressed, making overeating much more probable."
An Ongoing Issue?
The NHS suggest the injections for individuals with obesity-related medical conditions, alongside recommended diet and exercise modifications.
Professionals say that, given the significant potential of relapse, the therapy should be considered long-term.
This perspective is echoed by drug manufacturers, who state that the results "highlight the long-term character of obesity," akin to managing conditions like high blood pressure.
User Experiences
People who have stopped the medication explain a powerful return of appetite.
"I experienced something activating and you become ravenous," said an individual.
This difficulty is worsened if patients have not developed sustainable lifestyle or habit modifications during treatment.
Growing Adoption
Survey data suggest that millions of adults in the UK have tried weight-loss jabs in the past year, with demand continuing to grow.
- Use is greater among females than males.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
In conclusion, experts stress that while GLP-1 drugs are potent agents for shedding pounds, they are not a permanent fix and long-term success relies on integrated lifestyle management.
