The total sample sizes of this study were 49 subjects filled out anthropometric and lifestyles questionnaires before and after Ramadan, and 39 subjects provided 2-day dietary records during regular days and during Ramadan. Before Ramadan, the body weight and BMI were 55±10.8 kg and 22±3 kg/m2, respectively. After Ramadan, the body weight and BMI were 55±11 kg and 22±3 kg/m2, respectively. The differences between the subjects’ body weight as well as their BMI reported before and after Ramadan were significant (n=49; p=0.008; and p=0.012, respectively). Energy, protein, fat, n-6 PUFA, and phosphorus reduced significantly from regular to Ramadan days (n=39; 1688±434 kcal to 1521±364 kcal, p=0.004; 65±21 g to 55±16 g, p=0.001; 62±21 g to 49±17 g, p<0.0001; 14±7 g to 9±4 g, p<0.0001; 839±234 mg to 736±216 mg, p=0.005, respectively). Of the lifestyles, exercise durations and daily food expenses in daily decreased significantly (n=49; 27±27 min to 16±19 min, p=0.002; 435956±27645 IDR to 36549±29937 IDR, p=0.02, respectively). The frequency of exercise significantly changed during Ramadan (n=49, p=0.002). The body weight, BMI; intake of energy, protein, fat, n-6 PUFA, phosphorus; lifestyles of food expenses, exercise durations, and frequency of exercise of young adult Indonesian Muslims decreased significantly during Ramadan fasting when compared those in regular days.
