Prolonged Water Fasting May Increase Inflammation, Stressing the Body: New Study
Sydney, Australia – A New study reveals that prolonged water-only fasting, while leading to weight loss, can paradoxically increase inflammation and stress within the body. This surprising finding challenges earlier assumptions about the benefits of extended fasting and raises concerns, particularly for individuals with pre-existing heart conditions.
The Unexpected Consequences of Prolonged Fasting
Prolonged fasting, defined as abstaining from energy intake for four or more consecutive days, has gained traction as a health intervention. However, the biological impact of this practice remains largely unknown. Researchers recently investigated the effects of medically supervised water-only prolonged fasts, averaging 9.8 days, followed by a guided refeeding period averaging 5.3 days, on the plasma proteome.
study Details and Findings
The study involved 20 volunteers with an average age of 52.2 years and a mean BMI of 28.8. A retrospective analysis of 1422 individuals undergoing modified fasting (average duration of 8.2 days) was also conducted to validate inflammatory response findings.
Key findings include:
- A 7.7% mean weight loss was observed, with increased serum beta-hydroxybutyrate confirming adherence to the fasting protocol.
- Plasma proteomics revealed adaptations such as preservation of skeletal muscle and bone, enhanced lysosomal biogenesis, increased lipid metabolism, and reduced amyloid fiber formation.
- Circulating beta-amyloid proteins Aβ40 and Aβ42, key components of brain amyloid plaques, were significantly reduced.
Despite these positive adaptations,the intervention also triggered an acute inflammatory response,characterized by elevated plasma C-reactive protein,hepcidin,midkine,and interleukin-8. This inflammatory response was further confirmed in the modified-fasting analysis.
Expert Insights
“Our hypothesis was that prolonged water fasting would reduce inflammation in the body,”
Says Dr. Luigi Fontana of the University of Sydney.
“However, we found the opposite was true – that prolonged fasting put stress on the body and increased the number of proinflammatory proteins in the blood, potentially increasing the risk of health issues for people with existing heart and vascular conditions.”
Breaking Down the Biological Impact
While prolonged water fasting offers some benefits, understanding its potential drawbacks is crucial. The recent study underscores that fasting isn’t a one-size-fits-all solution and may carry risks, particularly related to inflammation.
pro Tip:
Before considering prolonged fasting, consult with a healthcare professional, especially if you have underlying health conditions. Choice approaches like intermittent fasting might be a safer option.
Comparing Fasting Methods
| Fasting Method | Duration | Potential Benefits | Potential Risks |
|---|---|---|---|
| Prolonged Water Fasting | 4+ days | Weight loss, cellular repair | Increased inflammation, stress on body |
| Intermittent Fasting (e.g., 16/8) | Daily/Weekly | Weight management, improved insulin sensitivity | Mild hunger, potential for overeating during non-fasting periods |
| Modified Fasting | Varies | Weight loss, some metabolic benefits | Inflammatory response, less extreme than water fasting |
Limitations of the Study
The study’s limitations include its single-arm design without a control group, the small sample size, and the variability in fasting and refeeding durations. Future research should address these limitations to provide more conclusive evidence.

The Evergreen Insights on Fasting
The popularity of fasting has surged in recent years, fueled by claims of weight loss, improved metabolic health, and even increased longevity. Though, it’s essential to approach fasting with a balanced understanding of its potential benefits and risks. A 2024 review in the “New england Journal of Medicine” highlighted the importance of personalized approaches to dietary interventions, emphasizing that individual responses can vary significantly. Always consult with a healthcare professional before starting any fasting regimen, especially if you have pre-existing health conditions.
