New research suggests that people who discontinue popular weight-loss injections like Mounjaro or Wegovy may regain reduced body mass much more quickly than those who halt conventional diet and exercise regimens.
Research printed in a leading health publication demonstrates that while overweight people can lose a large proportion of their body weight while on the medication, the mass returns at an estimated rate of 0.8 kg per month after stopping.
"Users using these drugs should be aware of the potential of fast weight regain when the treatment is stopped," cautioned researcher Dr. Susan Jebb.
Such speed of recovery means a return to pre-treatment weight in about one and a half years.
Analyzing Approaches
The analysis, which looked at 37 of studies involving over 9,000 of participants, contrasted the results of these new drugs with conventional dieting.
The team emphasize that people who shed pounds through lifestyle changes alone usually see a more gradual creep back—around 0.1 kg a month—after stopping.
Explaining the Fast Regain
Experts propose the mode of action of the drugs explains the accelerated rebound.
The injections imitate a natural hormone called glucagon-like peptide-1, which controls feelings of fullness.
"Sustained high doses of GLP-1 concentrations far above than normal may cause the system to produce less of its own natural hormone, and could lessen responsiveness to its effects," said Dr. Adam Collins, a dietetics expert.
"Withdrawal of this GLP-1 'fix' means appetite is unsuppressed, making excessive eating far more likely."
An Ongoing Condition?
Health authorities advise the injections for individuals with obesity-related health risks, alongside prescribed lifestyle changes.
Professionals argue that, given the significant potential of weight regain, the treatment might need to be ongoing.
This perspective is reinforced by drug manufacturers, who say that the findings "highlight the long-term character of excess weight," akin to managing diseases like diabetes.
User Testimonies
Users who have come off the medication describe a intense resurgence of hunger.
"It felt as if a trigger activating and I was suddenly starving," described an individual.
This difficulty is exacerbated if patients have not developed sustainable lifestyle or habit modifications during therapy.
Significant Interest
Recent estimates indicate that millions of adults in the UK have tried weight-loss jabs in the past year, with demand remaining high.
- Use is greater among females compared to men.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion access the medications through private healthcare rather than the NHS.
In conclusion, researchers caution that while GLP-1 drugs are effective agents for weight loss, they are not a permanent solution and lasting health benefits hinges on combined behavioural management.
