Outpatients with lifestyle diseases (n = 131) were provided nourishment guidance in the clinic; after 6 months, these patients were examined. Symptoms and signs improved in 46 individuals (35 %). remained unchanged in 31 (24 %). and aggravated in 54 (41 %). The 46 individuals who showed improvement included 38 who required fewer medicines and 3 who no longer required medicines. We found that hypertension improved when body weight decreased by ?2% and that improvement in hypertension was related to decrease in weight. However, in patients with hypertension and hyperlipemia, this was not so. A nutrition guidance program for outpatients is effective in improving dietary habits, decreasing body weight, and improving symptoms and signs of diseases. This may result in reduction of the number of medicines required and discontinuation of regular hospital visits.
