Fresh analysis reveals that people who come off popular slimming jabs like Mounjaro or Wegovy may regain reduced body mass far faster than those who stop traditional lifestyle regimens.
Research printed in a leading health publication demonstrates that while obese individuals frequently drop substantial amounts of their body weight while using the jabs, the weight returns at an estimated rate of 0.8 kg per month upon discontinuation.
"People purchasing such treatments need to be cognizant of the risk of rapid weight regain when the treatment concludes," stated researcher Dr. Susan Jebb.
That rate of recovery suggests a reversion to starting weight in about 18 months.
Weighing Therapies
The research, which examined 37 of trials involving thousands of patients, contrasted the results of the injectable medications with conventional dieting.
Researchers note that individuals who lose weight through lifestyle changes alone generally have a slower weight regain—approximately 0.1 kg a month—post-intervention.
Understanding the Fast Regain
Doctors propose the mode of action of the drugs explains the accelerated regain.
These medications copy a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Long-term administration of the hormone concentrations far above than normal might result in the system to generate a reduced amount of its own natural GLP-1, and may also reduce sensitivity to its effects," said Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement results in hunger is uncontrolled, making binge eating a significant risk."
A Chronic Disease?
Medical guidelines recommend the injections for individuals with obesity-related health risks, alongside recommended diet and exercise modifications.
A number of clinicians argue that, given the significant potential of relapse, the therapy is often ongoing.
This view is echoed by pharmaceutical companies, who say that the results "underscore the long-term character of obesity," comparing it to managing diseases like diabetes.
Patient Accounts
People who have discontinued the medication report a sudden resurgence of cravings.
"It was like a trigger flipping and you're instantly extremely hungry," described a patient.
This difficulty is worsened if patients have not developed sustainable lifestyle or habit modifications during therapy.
Significant Adoption
Survey data indicate that a significant number of adults in the UK have tried weight-loss jabs in the last 12 months, with interest continuing to grow.
- Use is greater among women compared to males.
- The 40s and 50s age group shows the greatest level of interest.
- Many obtain the drugs through private prescriptions rather than the NHS.
In conclusion, clinicians emphasize that while the jabs are effective agents for shedding pounds, they are not a standalone cure and lasting health benefits relies on integrated lifestyle management.
