Abstract
OBJECTIVE:
Fat oxidation during exercise depends on nutritional state, and exercise performed in the post-absorptive state oxidizes more fat than that performed in the postprandial state. However, the effects of exercise on energy metabolism continue during the post-exercise period, and the difference in fat oxidation during exercise may be compensated for during the post-exercise period. The present study compared the effects of an acute exercise bout in the post-absorptive or postprandial state on 24h fat oxidation.
METHODS:
Twelve young male athletes stayed twice in a room-size metabolic chamber for 24h indirect calorimetry in a randomized repeated-measure design. Before or after breakfast, i.e. in the post-absorptive or postprandial state, subjects exercised at 50% VO(2) max for 60min.
RESULTS:
During the 60min of exercise, energy expenditure in the two exercise trials were equivalent, but exercise in the post-absorptive state was performed with lower RQ compared with that in the postprandial state (P<0.01). The time of exercise relative to breakfast did not affect 24h energy expenditure (P>0.5). However, accumulated 24h fat oxidation was higher (P<0.05) and that of carbohydrate oxidation was lower (P<0.05) when exercise was performed in the post-absorptive state.
CONCLUSIONS:
Compared with exercise performed in the postprandial state, exercise performed in the post-absorptive state oxidized more fat and saved more carbohydrate in the body, without affecting 24h energy expenditure.

for idiots like myself - what would this translate into as far fas diet and exercise in setting up a schedule?

Lol. I competed in 5 shows, track n field, did MMA for years, BJJ, lifting for 20 years etc.
I could be ready for a show in 6 weeks if I had to.

I used to work out at Gold's Yonkers Ave., back in the day. Its right near the Bronx border and there were a lot of guys like that. Wraps, chalk, bags, belts, etc, all for a few half reps in a cage, sort of like Kamali.
However, there were tons of gorillas back then over there. They changed to Planet Fitness and threw me out the second day because they said I was not the image they wanted.

How many hours does it take for your body to enter in a 'fasted' state? Is 6 hours enough with the last meal being something light?

A blood glucose monitor can help determine this but a ketone tester is more accurate. 12 hours is the standard I believe.

Ok, thanks :)

supposedly one can go bout 60 hours in a fasted state before it becomes a catabolic state
they talk about this on the leangains site

a catabolic state is a marketing invention... same as an anabolic state... both are misnomers... your body doesn't work that way
more accurate ways to view the body are in a starved state or a fed state... but people have built muscle in both states and lost muscle in both states
there is a shit load more involved in gaining/losing weight than just food (stresslevel or BMR for example)
berkhan has some good ideas but he's not a genius
