Day 1 and 2 of the protocol were strictly controlled and consisted of an energy-restricted diet providing two-thirds of estimated energy needs.To calculate the tindividual energy needs of each subject,the basal metabolic rate was estimated by using the equation of Schofield: BMR(MJ)=0.0483xweight(kg)+3.67 Then, the physical activity level was estimated from a short retrospective physical activity questionnaire containing 6 activities.Basal metablic rate and physical activity level were used to estimate individual energy needs: E=BMRxPAL Taking one-third of the individual energy needs and rounding these values up in energy groups of 0.8 MJ resulted in 15 subjects receiving 4.2 MJ/d, 14 subjects receiving 5.0 MJ/d, and 5 subjects receiving 5.8 MJ/d. The energy-restricted diet consisted of nutrient-dense meal and snack replacements,each of which contained 0.8MJ,that were supplied at the beginning of the study. 我是最後一段看不懂,顺便把前文附给大家,比较易懂~ 谢谢大家!感激不尽!! --
