Study Summary

The overarching aim of this study: To determine the effect of different meal compositions (high- vs. low-fat) on metabolic flexibility as it relates to meal-stimulated change in respiratory quotient (ΔRQ1) and sleep (ΔRQ2) metabolic flexibility, as well as the time course changes in respiratory quotient, RQ (i.e., peak RQ, time to peak RQ, nadir RQ, time to nadir, slope).

Primary Outcome

12-h mean of respiratory exchange ratio following each meal type. measurement interval = 12h following start of meal (7pm) The respiratory exchange ratio refers to the proportion of macronutrients being oxidized. A respiratory exchange ratio value of 1.0 indicates only carbohydrates are being oxidized, while a ratio value of 0.7 indicates only fats are being oxidized. Intermediate values, such as 0.85, indicates that both carbohydrate and fats are being oxidized.

Interventions

  • OTHER High fat meal
  • OTHER Low fat meal
