Vail Symposium: Increasing Resting Fat Metabolism

FIN’

Understanding Fat Metabolism

• RESPIRATORY EXCHANGE RATIO– Metric of fuel economy for skeletal muscle

RER = FAT = 0.70 CARB =

1.00“An inability to oxidize lipids appears to be an important factor in the etiology of obesity and type 2 diabetes.”

-Jeukendrup Nutrition Volume 20, Numbers 7/8, 2004 Optimizing Fat Oxidation Through Exercise and Diet

Shifts in Resting Fat Metabolism

• Changes in dietary status– Diet in this country (et al) has been largely

composed of carbohydrates– Reluctance to include fat in diet due to false

information• Changes in Exercise status

– Low intensity exercise has been shown to increase chronic fat dependency

ENZYMATIC REGULATION


CARB FAT


Shifts in Resting Fat Metabolism

• Low intensity exercise:– Burns fewer calories than HIIT– Hurts less so it must be less beneficial– Requires MASSIVE volume of exercise to benefit

• In actuality…– Has a greater impact on oxidative enzyme activity– Is shown to have more influence on VO2 max– Positively effects resting fat metabolism– More consistent daily energy levels

LOWER RESTING RER VALUES
