New research reveals that people who discontinue new weight-loss injections like semaglutide or tirzepatide may regain lost weight far faster than those who end traditional lifestyle programs.
Published data in a prominent medical journal shows that while obese individuals can lose a large proportion of their body weight while using the jabs, the mass returns at an average rate of 0.8 kg per month upon discontinuation.
"Users using such drugs must be aware of the potential of rapid rebound weight gain when the therapy is stopped," warns expert Dr. Susan Jebb.
This pace of regain suggests a reversion to starting mass within about a year and a half.
Comparing Therapies
The research, which examined 37 of studies involving thousands of participants, contrasted the outcomes of GLP-1 agonists with other pills.
Scientists note that individuals who shed pounds through lifestyle changes alone usually see a more gradual creep back—approximately 100 grams monthly—post-intervention.
Understanding the Rapid Regain
Doctors suggest the way of the jabs is key to understanding the heightened weight return.
The injections copy a body's own chemical called GLP-1, which controls feelings of fullness.
"Sustained high doses of GLP-1 concentrations several times higher than normal could lead to the body to generate a reduced amount of its endogenous hormone, and may also lessen sensitivity to its actions," noted Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this GLP-1 'fix' results in hunger is uncontrolled, making overeating far more likely."
A Chronic Condition?
Medical guidelines suggest the injections for people with weight-linked medical conditions, alongside prescribed lifestyle changes.
Professionals contend that, given the high risk of relapse, the treatment should be considered long-term.
This opinion is reinforced by pharmaceutical companies, who state that the findings "highlight the chronic character of obesity," similar to managing conditions like diabetes.
Patient Experiences
Individuals who have stopped the jabs report a intense return of cravings.
"It felt as if a trigger that goes on and you become starving," described a patient.
The struggle is compounded if individuals have not adopted sustainable lifestyle or habit changes during treatment.
Widespread Interest
Survey data indicate that a significant number of adults in the UK have used these injections in the last 12 months, with interest continuing to grow.
- Use is greater among females than males.
- The middle-aged age group shows the highest usage rates.
- Many obtain the medications through private healthcare rather than public health services.
Ultimately, experts emphasize that while the jabs are potent tools for shedding pounds, they are not a magic fix and lasting health benefits likely depends on combined lifestyle changes.
