Introduction: Increasing rates of obesity, diabetes and associated chronic diseases requires implementing a new method of integration for healthy longevity. We have elaborated to take the balance of food, physical activity and mind to achieve a healthy spiritual life by stimulating the self-healing capacity.
Objectives: All 161 registered participants to ARSOA Wellness Fasting from October, 2014 to December 2015 were analyzed.
Methods: About 20-25 participants each time stayed in a mountainous hotel, and received a combination of low-energy vegetarian diet (about 300 kcal intake by fermented vegetable juice per day), physical exercise (2-hour walking, slow training and stretch), meditation, and lectures about healthy life habits in the 4-day program. Facilities, such as foot spar, radon bath, and massage with/without oil were available in free time.
Results: Body weight decreased about 2 kg, and fat percent and muscle volume also decreased during 4 day fasting. Although headache, hungry, gastrointestinal (GI) tract distress, emesis, depressive and cold feeling occurred toward the 2nd day, these symptoms disappeared at the 4th day, and active and vivid feeling increased on the 4th day and after. Skin condition also became good by fasting. Symptoms, mood and body changes interacted and became better later.
Conclusion: Using this regimen, a new practical method of fasting for healthy longevity could be established.

Diabetes mellitus, hypertension, and so on are linked to the obesity and metabolic syndrome. Existing guidelines, however, to help people achieve lifestyle change are difficult to practice.1 Japanese life expectancy is 86 years for women and 81 years for men. Along with the extension of life span, discrepancy between lifespan and healthy life causes problem due to huge expansion of medical cost.2 According to the Japanese government official, healthy life expectancy was 74.2 years for women, and 71.2 years for men, so it is nearly 12 years intervals for women and 10 years for men that needs any type of care to live.3 Here, healthy life is defined as not having activity limitation due to the health reason. Dietary control and physical activity are main factors to keep wellness and longevity but a combined method is still under developing.

Since ancient times, fasting has been performed for religious reasons or as a cure of diseases. Takahira4 was at the vanguard of fasting therapy in 1910-1920. He studied precisely the metabolic changes caused by fasting, and reviewed the efficacy of fasting therapy in various disease states. Mitsuo Koda5 developed fasting dietary therapy for various diseases, and confirmed beneficial effects for many patients with intractable diseases.

However, fasting method for healthy longevity or daily wellness has not been established. Our group had practiced macrobiotics for more than 10 years, and visited various fasting groups from 2005 to 2014.6 Upon these experiences we developed the teaching and practice system in 4-day “Wellness-fasting”. Daily nutritional intake was about 300 kcal by fermented vegetable juice (Ko-so). Many women had light headache in daily life, which became worse during fasting, but finally it disappeared, and substituted to vivid and active feeling to do something.

Our method could encourage participants to be a leader of health promotion by combining foods and health, and spiritual life. In this paper, we summarized the results of about 160 participants from October 2014 to December 2015.


The anthropometric data, blood pressure, pulse rate and body temperature are shown in Table 3. Age of participants ranged from 20 to 74, and most participants were women, who were working mostly in cosmetic shops as a sales lady or owners.

There were no current smokers. Their lifestyle was healthy and about half of them were ovo- and fish-vegetarians. BMI, blood pressure, body composition and body temperature were all within the normal range.

Changes of body weight, BMI, fat percent, blood pressure and pulse rate during 4 day wellness fasting is shown in Table 4. Body weight was lost 2.6 kg in males and 1.7 kg in females at median. Body fat rate decreased 1.3% and 0.7% in males and females, respectively, and muscular weight decreased 1.4 kg in males and 0.8 kg in females.

Systolic blood pressure decreased 12 mmHg in both males and females, and 5 mmHg and 6 mmHg in diastolic pressure in males and females, respectively. On the contrary, the pulse rate increased 10 in males and 7.5 in females at median. Body temperature decreased 0.2-0.3 oC in both sex.

Changes of self-reported condition during 4 days are shown in figures (Figures 1 and 2). Slight headache was a complaint of about one third women, and the prevalence increased toward 3rd day, but it decreased thereafter to only 10% in females. Hungry was highly recognized among males, but high prevalence was only 2 days. Feeling of coldness was common complaint of women, and it improved only 15%. GI tract distress was rather stationary around 20%. Vivid feeling and activity increased toward the end of fasting. In males increase of vivid feeling was remarkable at day 4 and day 6. Active feeling and vivid mood were significantly associated with skin condition.

Hungry, GI distress and feeling of emesis were significantly associated with fat, muscle weight reduction and decreased BMI. General condition, sleepy feeling, fatigue, depressive feeling, headache, cold feeling, GI distress and hunger were varyingly interrelated. Structure Equation Model by AMOS showed that a significant multiple effects of body fat rate, obesity, body weight, muscle volume and systolic blood pressure at day 2 and day 3 was recognized to those at day 4 (Figure 3).

Subject symptoms, such as skin condition, hungry, cold feeling, GI distress and headache 1 month later was significantly influenced by those of day 2 (Figure 4).

Symptoms, mood and body changes interacted and became better in later days.


In 1999, during the International Year of Older Persons, World Health Organization (WHO) launched a new campaign highlighting the benefits of Active Ageing.7 This was in perfect harmony with the slogan for the International Year “Towards a Society or All Ages” as Active Ageing highlights the importance of social integration and health throughout the life course. Dr. Gro- Harlem Brundtland, Director General of WHO stated “there is much the individual can do to remain active and healthy in later life”. The right life style, involvement in family and society and a supportive environment for older age all preserve well being.

It is important to make strategies required at the services delivery level and possible tools for implementation. Integrated organization by various health providers, such as physicians, nurses, dieticians, physical exercise trainers, pharmacists, therapists, and others, work together putting people at the center.3 It should be important to set standards for team-based care through multidisciplinary learning based upon the theoretical and practical learning.

In response to increasing rates of obesity and associated chronic disease, Japan has implemented several policies, guidelines and programs. Kenkou Nippon 21 (Health Japan 21) began in 2000,9 followed by the Shokuiku (food and nutrition education) Basic Law which was passed in 2005.10,11 Subsequently, in 2008, the government launched a special health check-up (tokutei kenkou shinsa), involving measurement of waist circumference and nutrition counseling to reduce metabolic syndrome.12

However, despite of these programs and guidelines, obesity remains a public health problem in Japan. In addition, discrepancy between lifespan and healthy life expectancy causes another problem by huge expansion of medical cost.13The difference was nearly 12 years for women and 10 years for men, and it is not shrunken despite of the implementation of various health strategies for elderly care.

Various dietary therapies to control health and body weight have been proposed, such as macrobiotics, Atkins diet, Zone diet, Ornish Diet, Learn Diet, etc.14 We had supported basically Macrobiotics,6 and elaborated to take the balance of food, physical activity and mind to achieve a spiritual life. It is relevant of the Koda’s fasting therapy,5 in which unpolished brown rice and green vegetable paste constitute the basic regimen, and it improves the intestinal environment by resolving constipation. Koda’s method could repair the balance of autonomic nervous system, so it may not only be effective for gastrointestinal disease, but also for some neurodegenerative diseases.

Although control of total energy intake is essential to control obesity, individual awareness and practice are also important. 14 We developed a weight loss program based on a behavioral approach with dietary and exercise intervention (Saku Control Obesity Program (SCOP)) in Japan.15-17 In this program, we emphasized individually-tailored counseling, instead of uniform class room teaching, and the diet and physical activity were designed for each participant.18-20 Half participants succeeded to reduced more than 5% body weight, and to change to the good lifestyle.

In ARSOA Wellness Fasting method is the combination of a low-energy vegetarian diet (about 300 kcal fermented vegetable juice per day, and multivitamin and mineral supplement), physical exercise (walking, slow training and stretch), meditation, foot spar, radon hormisis, and self massage with/without oil to stimulate the self-healing capacity. Using this regimen, a new concept of fasting for healthy longevity would be established.

The changes of mood were related to the body change. Headache was the most popular symptom, as one 3rd female participants had slight headache at registry, but it remarkably improved after fasting. Hungry and GI distress, nausea appeared on the second and 3rd day, but these improved toward the end. Blood pressure and fat percent significantly decreased by fasting, and body temperature tended to become lower. The active and vivid feeling increased on fourth day, and it lasted even at one month later.

It has been shown that a few days fasting caused many metabolic changes including various hormones and free fatty acid.21 The altered metabolism by fasting needs further study, because fasting seems to cause switch fuel from carbohydrate to fatty acid, as shown by the increase of ketone bodies in the urine.22 Cahill23 studied metabolic changes during 40 days of starvation and found that β-hydroxybutyrate replaces glucose as a source of energy. Fasting causes many metabolic changes.24

We suggested the contribution of intestinal microbiota was also important.25 We considered the increased β-hydroxybutyrate should influence on both mental and somatic symptoms. Butyrate made by intestinal microbiota could be metabolized to β-hydroxybutyrate in the body, so these should be further studied in the near future.
