New research indicates that individuals who discontinue new weight-loss injections like semaglutide or tirzepatide tend to recover lost weight far faster than those who halt conventional diet and exercise plans.
Findings released in a prominent medical journal shows that while obese individuals often shed substantial amounts of their body weight while on the medication, the mass returns at an estimated rate of 0.8 kg per month upon discontinuation.
"Users purchasing such medications should be cognizant of the risk of quick weight regain when the medication concludes," stated researcher Dr. Susan Jebb.
Such speed of regain implies a return to starting mass in about a year and a half.
Comparing Treatments
The analysis, which looked at dozens of trials involving thousands of patients, contrasted the results of the injectable medications with conventional dieting.
Researchers note that people who lose weight through dieting usually see a more gradual weight regain—around 100 grams monthly—once they finish.
Explaining the Fast Rebound
Nutrition scientists propose the way of the injections accounts for the accelerated rebound.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which controls hunger.
"Artificially providing GLP-1 concentrations several times higher than the body's typical production might result in the body to produce less of its endogenous GLP-1, and could diminish responsiveness to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this GLP-1 'fix' leads to hunger is unsuppressed, making overeating much more probable."
An Ongoing Disease?
Medical guidelines recommend the jabs for individuals with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians say that, due to the likelihood of relapse, the therapy should be considered long-term.
This perspective is echoed by drug manufacturers, who note that the findings "highlight the chronic nature of obesity," akin to managing diseases like hypertension.
User Accounts
Individuals who have discontinued the medication explain a sudden return of cravings.
"It felt as if something flipping and you become starving," said a patient.
The struggle is worsened if patients have not developed lasting dietary or behavioural changes during treatment.
Widespread Adoption
Survey data show that a significant number of people in the UK have tried these injections in the last 12 months, with demand being substantial.
- Use is greater among women than men.
- The middle-aged age group shows the greatest level of interest.
- Many access the medications through private prescriptions rather than public health services.
In conclusion, clinicians emphasize that while these medications are effective tools for weight loss, they are not a magic fix and long-term success likely depends on ongoing lifestyle support.
