Hey guys , i am only three days into eating paleo and am enjoying it, but i have a question. My diet for the last three days has been three eggs and some free range ground beef for breakfast, a big ass chicken salad with evoo and lime juice for lunch, some nuts for snacking and meat and veggies for dinner. The only carbs have been veggies and a little tomato on the salad.

I went mtn biking for an hour today. It was very hot and humid, which i usually dont like, but i really felt lethargic, somewhat due to the heat, but I am wondering if this is the low carb flu? Should i have eaten some fruit before or after riding? Are my carbs too low? I feel great outside of the rough ride. Thanks!
