All data are expressed as median (range). EI: energy intake; RDA: recommended daily allowance
aAge at the start of the weight loss programme
bMean energy intake expressed as metabolisable energy (in kJ [Kcal]) per kg of metabolic body weight (BW0.75) per day
cMean rate of weight loss expressed as percentage of starting body weight per week
dPercentage change in fat or lean mass between the start and end of the weight loss period; positive and negative values represent gains and losses in lean mass, respectively
eDummy variable created whereby 1 = the mean daily intake of each nutrient less than the NRC 2006 RA, and 0 when it was greater [15]
fDummy variable created whereby 1 was assigned when the minimum daily intake of the nutrient less than the NRC 2006 RA, and 0 was assigned when it was greater [15]
