  1. Note: * highest diet for acetone build, ** liquid protein-energy meal: Total Fat: 12 g, Total Carbs: 31 g, Protein: 18 g; Fat: (carbohydrate + protein) by mass = 12 g/49 g = 0.24; *** No information on content of fat or proteins is provided. In addition, no level of energy balance (negative or equilibrated) is provided to determine whether the subjects had any additional effect from calorie restriction.
