Shifting perspectives – interplay between non-alcoholic fatty liver disease and insulin resistance in lean individuals

Table 2 Definitions of metabolic health in non-obese

Definitions of metabolic health in non-obese individuals:
Absence of insulin resistance	Meigs et al[62]; Stefan et al[63]
Absence of insulin resistance and low CRP levels as a surrogate marker for inflammation, in combination with up to any two parameters of metabolic syndrome	Wildman et al[64]; Karelis et al[65]
Combination with up to any two parameters of metabolic syndrome	Stefan et al[66]; Phillips[67]
Definition of metabolically unhealthy non-obese individuals:
BMI < 25 kg/m2 and presence of insulin resistance	Stefan et al[23]
Waist circumference adjusted for BMI and/or android gynoid ratio and presence of insulin resistance	Suggested by authors

BMI: Body mass index; CRP: C-reactive protein.
