Japan becomes the super aged society. It is expected from now on that the population of the elderly person increases more and more. Therefore, disease prevention such as sarcopenia and frailty in the elderly person is required. This study tried the improvement of meal contents by taking in soy protein using caloric-tofu in daily life. The ten elderly people (one man, 9 women: from age 55 years old to 83 years old) who submitted the written consent of the subject participated in this study. We performed the gene analysis (β3AR, UCP1,β2AR) of the subject. The subject lived a normal life every day. The subject had eaten two high caloric-tofu a day. A caloric-tofu has 100 kcal. The subject participated in a study for two months. As for the subject, body composition was measured on the first day and two months after the start of the experiment, and six months after the end of the experiment. As a result, skeletal muscle rates of five people increased slightly, and body fat rate decreased slightly. However, five people changed into neither the skeletal muscle rate nor the body fat rate. Six months after the end of the experiment, the pair composition results were kept almost the same as at the end of the experiment. It can be highly appreciated that in the effective group, the pair composition could be maintained in a better condition than at the beginning of the experiment. For elderly people, the effective group, it is significant that intake of high caloric-tofu is effective in increasing the rate of skeletal muscle, and the effect is maintained even after half a year.
