Fresh analysis indicates that individuals who come off blockbuster weight-loss injections like Mounjaro or Wegovy tend to recover lost weight far faster than those who end conventional diet and exercise regimens.
Findings released in a leading health publication demonstrates that while overweight people often shed about a fifth of their body weight while using the jabs, the weight is regained at an estimated rate of 0.8 kg per month after stopping.
"Individuals using such medications must be cognizant of the risk of quick weight regain when the therapy concludes," cautioned researcher Dr. Susan Jebb.
That rate of regain implies a return to starting weight in about one and a half years.
Analyzing Treatments
The study, which examined 37 of studies involving over 9,000 of patients, contrasted the outcomes of GLP-1 agonists with other pills.
Scientists point out that people who shed pounds through diet and exercise usually see a less rapid creep back—around 0.1 kg a month—once they finish.
Understanding the Rapid Rebound
Experts believe the mode of action of the jabs explains the accelerated rebound.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of the hormone levels far above than normal may cause the body to generate a reduced amount of its own natural GLP-1, and may also reduce responsiveness to its actions," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this hormone supplement means appetite is uncontrolled, making overeating a significant risk."
A Lifelong Issue?
Medical guidelines recommend the jabs for individuals with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
A number of clinicians contend that, considering the significant potential of weight regain, the treatment should be considered long-term.
This perspective is reinforced by drug manufacturers, who state that the results "emphasize the persistent nature of obesity," comparing it to managing conditions like high blood pressure.
User Experiences
Individuals who have stopped the medication describe a sudden return of cravings.
"It felt as if a trigger activating and you're instantly ravenous," described an individual.
This difficulty is exacerbated if users have not developed permanent lifestyle or habit modifications during therapy.
Significant Use
Survey data suggest that a significant number of adults in the UK have tried weight-loss jabs in the past year, with demand being substantial.
- Adoption is more common among females than men.
- The middle-aged age group shows the greatest level of interest.
- Many access the drugs through private healthcare rather than the NHS.
In conclusion, clinicians caution that while these medications are powerful tools for weight loss, they are not a standalone fix and long-term success hinges on combined behavioural changes.
