give this a read...mainly the discussion/summary at the end...

Could you maybe paste the summary here, or the part of it you find interesting?

"Exercise and fasting are effective means to increase
fat oxidation. Thus exercise is often prescribed to
individuals attempting to reduce body fat. Our present
findings indicate that when exercise is preceded by a
carbohydrate meal, lipolysis and fat oxidation are
reduced. How this affects body fat and weight regulation
over periods of days to months is not clear. It has
recently been reported that total fat oxidation was
reduced ,30% over an 8-h period when carbohydrate
was ingested before exercise, compared with ingestion
after exercise (27). Reducing lipolysis and impairing
daily fat oxidation by ingesting carbohydrate before
exercise increases the likelihood of being in a positive
lipid balance and thus may increase fat deposition."
"Due to the sensitivity of lipolysis to
even small elevations of insulin, it appears that to
maintain high rates of fat oxidation at rest and during
subsequent exercise, people should not eat even small
amounts of carbohydrate before exercise."
"The present findings demonstrate that carbohydrate
ingestion before exercise resulting in a 10–30 μU/ml
elevation in plasma insulin concentration reduced fat
oxidation primarily by suppressing lipolysis during
exercise."

So, if I understand correctly, we should take some type of "carb" meal/drink before exercise? I usually eat half a tub of fat free cottage cheese before exercise because it has the 2.5 to 1 of protein to carbs (14 grams of protein to 5 grams of carbs per serving). So I eat about 3 1/2 servings. :)
NO. It means we should NOT. You want fax oxidation or the process of metabolizing fat, if we inhibit that, we loose less fat...so tghe paper is saying, to burn as much fat as possible, don't eat carbs before cardio.
