This study will explore, in an exploratory manner, the effects of a diet with large daily variations in major macronutrients on glucose metabolism, lipid metabolism, and health-related markers, to determine whether such dietary habits are effective in improving metabolic flexibility (insulin resistance) and maintaining health.

The participants alternate between low-carb and low-fat days for six days. The combination of the low-carb and low-fat days results in a nutritionally balanced diet based on the Dietary Reference Intakes.
Participants will be required to eat a nutritionally balanced diet based on the dietary reference intakes for six days.
