Runners I have a question for you. I remember back when I ran all the time it acted as an appetite suppresant, not stimulant like most people. After my run yesterday I could barely eat, I felt nauseated all evening. Any thoughts on what this is? Is it blood sugar going wonky from the long runs? It has actually been plaguing me all week (even after the 30 minute runs), I have a decent appetite breakfast and lunch but post run at dinner I can barely choke down anything.
