New research indicates that people who come off new slimming jabs like Mounjaro or Wegovy can put back on lost weight at a significantly accelerated pace than those who halt conventional lifestyle regimens.
Findings released in a prominent medical journal demonstrates that while obese individuals often shed a large proportion of their body weight while on the medication, the weight returns at an estimated rate of 0.8 kg per month upon discontinuation.
"Individuals buying such medications must be cognizant of the risk of quick rebound weight gain when the therapy ends," stated researcher Dr. Susan Jebb.
This pace of recovery implies a reversion to starting mass in about 18 months.
Comparing Approaches
The analysis, which looked at 37 of trials involving over 9,000 of participants, compared the effects of GLP-1 agonists with other pills.
Scientists point out that individuals who shed pounds through lifestyle changes alone usually have a less rapid creep back—around 0.1 kg a month—post-intervention.
Explaining the Quick Rebound
Nutrition scientists believe the mechanism of the injections is key to understanding the heightened rebound.
The injections mimic a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Artificially providing the hormone concentrations far above than normal may cause the system to generate a reduced amount of its own natural hormone, and could lessen responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' results in hunger is uncontrolled, making binge eating much more probable."
A Lifelong Condition?
Medical guidelines suggest the injections for individuals with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
Many experts contend that, considering the significant potential of weight regain, the therapy should be considered long-term.
This opinion is supported by drug manufacturers, who state that the results "highlight the persistent character of obesity," akin to managing conditions like diabetes.
Patient Accounts
Individuals who have stopped the jabs report a intense resurgence of cravings.
"It felt as if a trigger activating and you're instantly starving," described one woman.
This difficulty is exacerbated if users have not established lasting dietary or behavioural modifications during therapy.
Growing Use
Figures suggest that a significant number of people in the UK have tried these injections in the past year, with interest continuing to grow.
- Use is higher among women than men.
- The middle-aged age group shows the greatest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
In conclusion, clinicians caution that while the jabs are potent agents for shedding pounds, they are not a magic cure and lasting health benefits hinges on integrated behavioural support.
