The body burns all sources of fuel, fat, glycogen, and protein. The problem
with eating a day's worth of 1500 calories of fat is that fat is stored
very easily. No conversion is needed to store fat. With Carb's they are
converted then stored. The conversion process uses some of the calories in
the grams of carbs to convert them to fat, but, the excess carbs will still
be stored as fat. To lose fat, it's a bit more than what you eat, it's also
what you burn. The muscles burn glycogen very easily, so the carbs will
burn with almost a minimal effort. To burn fat takes much more effort. In a
nutshell use the big muscles, get your heartrate to at least 65% of max and
breathe.
