Fresh analysis indicates that patients who discontinue new weight-loss injections like Wegovy and Mounjaro may regain reduced body mass much more quickly than those who end conventional diet and exercise programs.
Findings released in a major medical journal points out that while obese people often shed about a fifth of their body weight while on the medication, the mass is regained at an estimated rate of nearly a kilo each month once they quit.
"Users using these medications must be cognizant of the danger of fast weight regain when the medication is stopped," stated researcher Dr. Susan Jebb.
That rate of regain implies a return to pre-treatment weight within about 18 months.
Comparing Treatments
The analysis, which reviewed 37 of studies involving over 9,000 of patients, contrasted the effects of the injectable medications with other pills.
The team point out that individuals who shed pounds through diet and exercise typically experience a more gradual weight regain—perhaps 100 grams monthly—once they finish.
Explaining the Fast Rebound
Doctors believe the way of the jabs is key to understanding the amplified rebound.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Artificially providing the hormone levels far above than the body's typical production could lead to the system to generate a reduced amount of its endogenous GLP-1, and could reduce responsiveness to its actions," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this hormone supplement results in hunger is no longer kept in check, making binge eating much more probable."
A Lifelong Issue?
Health authorities suggest the injections for individuals with obesity-related health risks, alongside prescribed lifestyle changes.
A number of clinicians contend that, considering the significant potential of relapse, the treatment might need to be ongoing.
This opinion is reinforced by drug manufacturers, who state that the results "underscore the long-term nature of excess weight," similar to managing diseases like hypertension.
Patient Testimonies
Individuals who have stopped the medication describe a intense return of hunger.
"It felt as if a switch that goes on and you're instantly starving," said an individual.
This difficulty is exacerbated if users have not established lasting dietary or behavioural modifications during treatment.
Significant Use
Recent estimates suggest that millions of adults in the UK have tried weight-loss jabs in the past year, with interest remaining high.
- Adoption is more common among females than males.
- The middle-aged age group shows the highest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
In conclusion, researchers emphasize that while GLP-1 drugs are potent tools for shedding pounds, they are not a magic fix and lasting health benefits relies on integrated lifestyle support.
