I thought this was a really good way of looking at your nutrition/eating
"It got real today. 1st day in my build up to defending my World Championship and it starts with saying no to sugar. This is not just for the obvious (not so obvious to everyone) benefits to me physically, but for me saying no to sugar keeps me mentally focused on my goal. It is a constant reminder, a frequent mental gym session, and often ego booster.
To know I have the strength to say no to all treats, to only eat what I believe to be good for me (natural food), is mental training for when it gets tough on race day and for a second my mind says “let’s quit”, a second later it says “let’s go faster” because I am strong in my mind, I am in control, because I practice being in control."
I don't like the fact he tosses around generic terms like "sugar" and "natural foods" but I get what he's saying and like how he makes his daily eating a part of his training. For me, I think I have food and training in two separate columns in my head and I like that he makes them one seamless part of his life.
I think what he's getting at here but not really saying is that food is fuel. Not entertainment or reward, but fuel. And I think that's a healthy approach to food. What foods are going to make me the most healthy in order to do the activities I need/want to do?
