When does the body burn fat?

[Guest guest]

Colleagues,

A paradigm to consider: human metabolism has evolved to store fat and minimize

lean mass. The natural selection strategy for feast-famine cycles is to store

energy (hence the role of adipose)and limit the amount of tissue with high

metabolic cost (like muscle). This is a result of our hunter-gatherer ancestry

and probably worked well when our survival depended on moving more regularly -

in which case energy expenditure would have been higher throughout the typical

day, and the stimulus to build or maintain lean mass was constantly present.

Now, however, our lifestyle makes this mechanism more problematic.

The take home message is that we need to trick this mechanism to an extent in

order to selectively lose fat while maintaining (orgaining) muscle.

The hormonal cascade triggered by food intake can be an even more potent

stimulus than training. Together, food and training can be used to significantly

change body composition. The key is to vary calorie intake as well as training

stress, a concept Dr. Siff described as " chrononutrition " .
