Based on the completed questionnaire and meeting the criteria, 11 participants (n = 11) were selected. The subjects underwent body composition analysis using bioimpedance, their resting energy expenditure was measured by indirect calorimetry, and blood was taken. The subjects then performed a 4-day food record (self-reported 4-day Dietary Record), which was analysed using new software. The complete dietary record was analysed for only eight subjects (n = 8).

Results: The average BMI of the subjects was 20.87 ± 1.58 kg/m2. Two subjects (n = 2) had a lower body fat percentage than is adequate. The biochemical blood test results indicated a possible vitamin D and iron deficiency. When comparing actual energy...
