[Human body function indices in the long-term feeding of a low-calorie diet composed of canned products]

Five healthy trained men aged 27-46 with a body weight approximating an ideal one were kept on a diet containing 95.4 g protein, 552.6 g carbohydrates and 81.3 g fat for 3 days, whereupon they received 1/3 of the indicated diet for 20 days. Energy losses averaged 2913 kcal/day. As a result of receiving the low-caloric diet (LCD), the body weight of the examined dropped from 75.8 to 70 kg. central nervous system function and higher nervous activity remained the same as shown by the reflexometry data, digital and corrections tests; the heart rate was 8-12 beats per minute lower in all the examined throughout all the observation periods both at rest and during exercise as compared to the respective characteristics of the adaptation period. The PWC170 value increased by 12-17% on the average. According to subjective data body function of the examined did not change substantially as a result of being fed the LCD.
