Subject:         Fueling Problem Question

Hi Dr. Graham.

I'm having some athletic fueling problems I was hoping you could help me with.

I'm 32, male, 6 ft, 178 pounds, aprox 12% BF.

Two to three times a week I like to spend the evening (about 2-4 hours) doing a
mix of parkour, gymnastics, acrobatics, and acro yoga with a group near

The exact combinations vary, but it's fairly strenuous.

I've been eating 80/10/10 for about three months, and I find that my ability to
stay fueled for these evenings has been compromised.

Previously on such days I'd eat no more than 3,000 calories of a cooked vegan
diet with perhaps 20% of calories coming from fat. My staple was potatoes. This
would be sufficient to fuel me all evening. I generally didn't stop for snacks, but
if I did it wouldn't be till the end, when I'd start to run low on fuel.

Since starting 80/10/10, I have more energy in the short term, and my
athleticism has improved.

But I keep running out of fuel, despite eating 3,300 to 4,000 calories on these
days. My major staples right now are bananas, grapes, and persimmons. I also
eat a big salad every evening (close to a pound of greens). I usually eat half of
an avocado.

I'm using a scale to weigh my food, so I think I'm being accurate.

My weight has not changed while eating this way.

I find I'm fine for an hour to an hour and a half of acrobatics, but after that I run
out of fuel.

I feel like I'm moving slowly and lethargically, and my desire to participate
declines before I hit the two hour mark. It's also hard to concentrate,
particularly when doing partner-based work that takes a lot of concentration in

I used to run marathons, and on several occasions I "hit the wall,". It's a lesser
version of that feeling.

Can you suggest what I might be doing wrong?

I really have no desire to eat more. I'm not hungry.

I try to eat a snack of bananas or a blended fruit, water, and celery sports drink,
and it may help me for a few minutes, but before long I'm out of fuel again.

Two More Questions:

1) Do you find that eating blended smoothies gives you gas? I have it on some
days, but not others, and the only connection I can find is that the those days
I'm eating smoothies.

2) Is there any downside of eating huge meals (1k to 1.5k calories) four hours
before an event (to allow time for digestion)? Will this become fat if it's not
immediately used?

I'd rather not stop for snacks during a workout.
