To elucidate the mechanisms of adaptation to a low-energy and low-protein vegan diet, we carried out dietary surveys and nitrogen balance studies five times during one year on two women and a man who ate raw brown rice, raw green vegetables, three kinds of raw roots, fruit and salt daily. Individual subjects modified this vegan diet slightly. The mean daily energy intake of the subjects was 18, 14, and 32 kcallkg, of body weight. The loss of body weight was about 10% of the initial level. The daily nitrogen balance was -32, -33, and 1lmg N/kg of body weight. In spite of the negative nitrogen balance, the results of routine clinical tests, initially normal, did not change with the vegan diet. Ten months after the start of the vegan diet, the subjects were given 15N urea orally. The incorporation of 15N into serum proteins suggested that these subjects could utilize urea nitrogen for body protein synthesis. The level of 15N in serum proteins was close to the level in other normal adult men on a low-protein diet with adequate energy for 2 weeks.
