RMR equations.

Author(s)	Year	Cohort Characteristics	Equation
Cunningham [9]	1991	n = 1483; meta-analysis, normal-weight and obese males and females, did not provide detailed age information	RMR = 370 + 21.6 FFM
Harris and Benedict [8]	1919	n = 239 (136 M, 103 F) Age = 29 ± 14 years	Male: RMR = 66.47 + 13.75 Wt + 5.00 Ht − 6.76 A Female: RMR = 655.09 + 9.56 Wt + 1.85 Ht − 4.68 A
Gougeon et al. [16]	2002	n = 65; with type 2 DM 40 F (age = 52 ± 1, BMI = 37 ± 1, FPG = 10.9 ± 0.5) 25 M (age = 54 ± 2, BMI = 37 ± 1, FPG = 10.0 ± 0.9)	RMR = 375 + 85 Wt − 48 FM + 63 FPG
Lührmann et al. [14]	2002	n = 281; over 60 years of age 179 F (age = 67.8 ± 5.7, BMI = 26.4 ± 3.7) 107 M (age = 66.9 ± 5.1, BMI = 26.3 ± 3.1)	RMR = 757 + 11.9 Wt − 3.7 A + 178 S
Nachmani et al. [10]	2020	n = 39 18 F (age = 45.5 ± 12.5, BMI = 32.0 ± 4.0) 21 M (age = 38.2 ± 11.0, BMI = 33.0 ± 3.0)	Male: RMR = 132.82 + 28.37 Wt − 205.59 Ht + 9.46 FFM − 2.87 A − 25.93 FM Female: RMR = 553.97 + 16.60 Wt + 1033.84 Ht − 13.73 FFM − 10.93 A − 19.67 FM

Note: Abbreviations: A = age (years); BMI = body mass index (kg/m²); Ht = height (cm; Nachmani equation = m); F = female; FPG = fasting plasma glucose (mmol/L); FFM = fat-free mass (kg); FM = fat mass (kg); M = male; Wt = weight (kg); RMR = resting metabolic rate (kcal/day); S = sex (female = 0, male = 1).
