Regarding carbs, you say there are no need for them in our diet, but is it the same if your exercise 1 to 2 hours per day ?

I usually like to eat some fruit about 1 hour before working out, and I notice better energy levels throughout my workouts when eating fruit than when eating just meat. 

 Same question. Nectarines, mangoes, grapes, melon, and blueberries top my list. 

 I think he said baseline is zero, but you may be able to take or need to take more carbs depending on tolerance and lifestyle.
