Design outcomes

Primary

MeasureTime frame
Lipid profile Baseline before meal consumption and 24 hours after completion of each dietary intervention session Venous blood sampling and biochemical analysis of total cholesterol, triglycerides, HDL cholesterol, and LDL cholesterol using standard clinical chemistry assays in a certified laboratory.

Secondary

MeasureTime frame
Fasting blood glucose level Baseline and after at least 10 hours of fasting at the end of each dietary intervention session enous blood sampling and measurement of fasting plasma glucose using standard biochemical assays,Resting metabolic rate Baseline before each dietary intervention session Indirect calorimetry performed in a quiet controlled room under fasting resting conditions,Anthropometric measurements and body composition Baseline and 24 hours after each dietary intervention session Body weight height waist circumference abdominal height and bioimpedance scale assessment using standardized measurement protocols
