New research reveals that individuals who discontinue new weight-loss injections like Wegovy and Mounjaro can put back on reduced body mass far faster than those who stop traditional lifestyle plans.
Findings released in a leading health publication points out that while overweight individuals frequently drop substantial amounts of their total mass while undergoing treatment, the weight comes back at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals using these treatments must be cognizant of the risk of fast rebound weight gain when the medication is stopped," warns expert Dr. Susan Jebb.
This pace of recovery implies a return to starting mass within about one and a half years.
Comparing Treatments
The research, which reviewed 37 of studies involving thousands of patients, contrasted the effects of the injectable medications with conventional dieting.
The team emphasize that people who lose weight through diet and exercise typically experience a more gradual creep back—around 100 grams monthly—post-intervention.
Explaining the Fast Rebound
Experts believe the mechanism of the drugs explains the heightened regain.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which helps regulate hunger.
"Long-term administration of GLP-1 levels several times higher than the body's typical production may cause the system to produce less of its own natural GLP-1, and could reduce responsiveness to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this hormone supplement means hunger is uncontrolled, making excessive eating far more likely."
A Chronic Condition?
Medical guidelines recommend the injections for individuals with weight-linked medical conditions, accompanied by recommended lifestyle changes.
Many experts say that, given the significant potential of weight regain, the therapy might need to be ongoing.
This opinion is supported by pharmaceutical companies, who say that the findings "highlight the chronic character of obesity," akin to managing diseases like high blood pressure.
User Testimonies
People who have stopped the medication describe a powerful return of hunger.
"It felt as if something flipping and I was suddenly starving," said an individual.
This difficulty is worsened if individuals have not developed permanent dietary or behavioural modifications during therapy.
Widespread Interest
Figures indicate that millions of people in the UK have tried these injections in the past year, with desire continuing to grow.
- Adoption is more common among women compared to men.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion access the drugs through private healthcare rather than the NHS.
In conclusion, researchers caution that while these medications are effective tools for shedding pounds, they are not a permanent cure and lasting health benefits likely depends on combined lifestyle support.
