I have been trying Intermittant fasting but struggle with only having coffee prior to my 9:00 am crossfit. Any recommendations?
I think it's bad idea. I haven't drunk coffee five years already.
I second Jason's post. You will need something to fuel your workout, which is were your carbs can come into play.
-Carbs before (sweet potato, white rice) along with the rest of your food.
-Optional BCAA's, or Gatorade during your workout.
-Carbs after (Fruit with your post workout whey protein shake)
On days that you workout, skip the fasting and make sure you get enough calories.
It is what it is.
