Experiments	Design
Experiment 1: manipulation of dietary protein levels under fixed fat contents	a. Two series of 6 diets with varying protein level (5, 10, 15, 20, 25, and 30%) b. Series 1 had 60% fat and series 2 had 20% fat content c. C57BL/6 mice exposed to all 12 diets d. BALB/c, C3H, DBA/2, FVB mouse strains exposed to 6 diets with high fat (series 1)
Experiment 2: manipulation of dietary fat levels under fixed protein contents	a. Two series of 6 diets with varying fat level (10% to 80% and 8.3% to 66.6%) b. Series 3 had 10% protein and series 4 had 25% protein content c. C57BL/6 mice exposed to all 12 diets d. BALB/c, C3H, DBA/2, and FVB mouse strains exposed to 6 diets with 10% protein (series 3)
