Koda’s Fasting Therapy: Energy Balance and Intestinal Bacterial Flora

Abstract

illnesses. Mitsuo Koda developed fasting dietary therapy and confirmed beneficial effects for
many patients with intractable diseases. About 900-1000 kcal/day by unpolished brown rice,
green vegetable paste and tofu constitute the basic regimen of Koda’s therapy. This case report
deals with women patient (M) who had suffered spino-cerebellar degeneration at a young age
and recovered by using Koda’s method. She had been living on only one glass of fresh vegetable
juice per day for 19 years since her acute episode at age 20. Four other persons who
were experimenting Koda’s method were asked to join the study for comparison. In our case
series, the Basic Metabolic Rate (BMR) was 1000-1200 kcal, which was equivalent with the
intake, but in case of M the nutritional intake was almost one tenth of others. M’s ketone bodies,
especially β-Hydoxy Butyrate (BHB) in the blood, were more than 3 mM, so the main energy
should come from ketone bodies. Biochemical changes of M coincided with the metabolic
adaptation to yield BHB, as shown by elevated Aspartate aminotransferase (AST), Alanine
aminotransferase (ALT) and Creatine Kinase (CK). High aspartate was a reflection of above
metabolic change. Increased BHB was observed in two participants, M and H, and both of
them had Bifidobacteriacae in fecal bacteria. Energy balance and biochemical changes were
discussed in these five subjects with calorie restriction.
