Abstract

Described herein are methods of determining energy balance in individuals such as exercising individuals, individuals consuming a 13C-enriched test composition and individuals consuming a fixed diet with a known δ13C. The δ13C pre- and post-exercise, or pre- and post-consumption of the test beverage or fixed diet indicate whether the individual is in neutral or positive energy balance, or in energy deficit. The methods are particularly useful for individuals participating in weight management programs, and individuals under the care of health care professionals.
