1Run-in diet values reported as average of intake per day, based on an energy intake of 2100 kcal/d. The energy content of the run-in diet was adjusted on an individual basis to meet the individual's daily energy requirement for weight maintenance, calculated using the Harris-Benedict equation [27] and adjusted with an activity factor of 1.4
2Test meal values represent an energy intake prescription of 2100 kcal/d. The energy content of the test meal was adjusted on an individual basis and provided 40% of the individual's daily energy requirement for weight maintenance. The amounts of foods served in the test meal were adjusted proportionately to maintain the same macronutrient ratios at all energy levels
3Glycemic index values [28] are based on the glucose standard and represent an average weighted by available carbohydrate in each food item constituting the test meal or run-in diet
