  1. *1All energy and nutrient intakes of the controlled food in the experiment were calculated according to the Standard Tables of Food Composition in Japan, and the coefficients for each food constituent were different from Atwater’s coefficients.
  2. *2LNAA: Large, neutral amino acids (isoleucin, leucin, phenylalanine, tyrosine, and valine).
