Relationship between insulin and NEFA concentrations. Top - Baseline data while on a 55% carbohydrate, 15% protein, 30% fat diet; Middle - following 5 weeks on a LoBAG30 diet; Bottom - following 10 weeks on a LoBAG30 diet. n = 8 subjects. The letters on the x axis indicate time of ingestion of Breakfast, Lunch, Dinner, and Snack. Units are μU/ml for insulin (closed triangles), and μEq × 10-1/L for NEFA (open circles).
