Thanks for all your replys.

I found this through a crossfit website link (intense interval- like
stregnth training site). Most people who practice intermittent fasting in
the crossfit community follow a "paleo type" or zone diet consisting
mostly of protein, veggies, fruits, healthy fats to optimize performance.
It seems from what I read about Fast-5, that there are not strict
guidelines on what types of food to be eating...

What kinds of food and how much food is everyone eating within the 5 hour
window? How long have you been doing this & is it realistic to think you
can do this long term in the society we live in?
thanks again!
Suzanne
