This is an open-randomized clinical trial of weight loss program as a part of a larger study researching the effect of low calorie high protein diet to body composition, oxidative stress, inflammation marker and metabolic syndrome in obese with weight cycling. Subjects were assigned to low calorie diet and were randomly distributed into two intervention groups, namely high protein group (22-30 % of total calories intake) and standard protein group (12-20%). Anthropometry, body composition data, and blood sample (for inflammation marker (HsCRP) and oxidative stress (malondialdehyde and glutathione)) were taken at baseline and at the end of the study. Subjects were followed up to 8 weeks with daily reminder and weekly counselling
