A moderate energy (0 g protein, 420 kcal) supplement was given daily to a group of people (n = 14) in one week, and a placebo was administered daily in another week. A second group (n = 13) was given a protein supplement (14 g protein, 84 kcal) daily during one week and a placebo in a separate week. A crossover design was used. The effect of the energy supplement was to increase the mean energy intake by 273 kcal, in the treatment compared with the placebo week. That is, 32% of the energy value of the drink was accommodated by a change in the diet; this change was not significant. The effect of the protein supplement was to increase the mean protein intake on day 1 by 20.5 g, in the treatment compared with the placebo week. This increment decreased linearly throughout the week, to 5.9 g on day 7. At lunchtime, carbohydrate intakes were significantly depressed after the protein supplement, and protein intake was significantly increased after the energy supplement.
在一周的时间里，每天给一组人（n = 14）服用中等能量（0克蛋白质，420千卡）的补充剂，在另一周每天给予安慰剂。第二组（n = 13）在一周内每天服用蛋白质补充剂（14克蛋白质，84千卡），在另一周服用安慰剂。采用交叉设计。与服用安慰剂的那一周相比，能量补充剂的作用是使治疗期间的平均能量摄入量增加273千卡。也就是说，饮料能量值的32%通过饮食变化得到了补充；这种变化不显著。蛋白质补充剂的作用是与服用安慰剂的那一周相比，在第1天使平均蛋白质摄入量增加20.5克。这种增加在整周内呈线性下降，到第7天降至5.9克。午餐时间，服用蛋白质补充剂后碳水化合物摄入量显著降低，服用能量补充剂后蛋白质摄入量显著增加。
