Sutton et al. • Cell Metabolism • 2018
Early 6-hour eating window improved insulin sensitivity by 36% without weight loss

60% achieved diabetes reversal while 94% reduced or eliminated insulin
Petersen & Shulman • Physiological Reviews • 2018
Ectopic lipid in liver and muscle is the primary driver of insulin resistance
Crofts et al. • Diabetes Research and Clinical Practice • 2016
Over 50% with normal glucose have hyperinsulinemia - earliest metabolic disease marker
Barbagallo & Dominguez • World Journal of Diabetes • 2015
Type 2 diabetes frequently associated with extracellular and intracellular magnesium deficits; intracellular Mg critical for insulin action and glucose uptake; benefits of supplementation found in most studies
Hayashi et al. • Diabetes Care • 2013
Pattern 4 (120-min peak, lower at 30 min): 47.8% diabetes incidence, OR 12.55 (95% CI 4.79-32.89) vs early peak patterns; Pattern 5: 37.5% incidence, OR 8.34
Thomas et al. • Obesity • 2012
TOFI individuals appear lean but carry elevated visceral and organ fat
Volek et al. • Lipids • 2009
Carbohydrate restriction reduced insulin 50% and improved sensitivity 55%
Volek JS et al. • Lipids • 2009
Carbohydrate restriction improved triglycerides, HDL, and metabolic syndrome markers more effectively than a low-fat diet
Gastaldelli A, et al. • Hepatology • 2009
Subjects with FLI >60 had IMT of 0.64±0.08 mm vs 0.58±0.08 mm in FLI <20. FLI correlated with CHD risk (r=0.48) and inversely with insulin sensitivity (r=-0.43).
Stefan et al. • Archives of Internal Medicine • 2008
Ectopic fat in liver and muscle, not BMI, determines metabolic health
Wildman et al. • Archives of Internal Medicine • 2008
23.5% of normal-weight adults have metabolic dysfunction; BMI alone misses risk
Fraser A, Longnecker MP, Lawlor DA • Gastroenterology • 2007
Elevated ALT (>30 U/L) associated with waist circumference and insulin resistance even in young population; males OR 7.7, fasting insulin per 1 SD OR 1.6
Rasi et al. • International Journal of Dermatology • 2007
Multiple skin tags indicate 3x higher diabetes risk; >30 tags = 52% diabetes
Chen H, et al. • Diabetes • 2005
QUICKI showed high accuracy as a surrogate for insulin sensitivity, with performance maintained across BMI categories and glucose tolerance status.
McLaughlin T, et al. • American Journal of Cardiology • 2005
TG/HDL ratio ≥3.5 identifies insulin-resistant, dyslipidemic individuals with sensitivity and specificity comparable to metabolic syndrome criteria
McLaughlin T, et al. • Annals of Internal Medicine • 2003
TG/HDL ratio ≥3.0 (mg/dL) or ≥1.3 (mmol/L) identifies insulin-resistant individuals with ~64-79% sensitivity
