So my doctor said yesterday that I need to eat more calories so I promised to go up to 500 per meal 3 times a day. Well this morning was the first time I did that and instead of having more energy to get through my swim session, I had way less! Seriously, what happened? I used to just eat a Cliff Bar (190 calories) and then go for my swim, last a half hour, refuel then swim another half. Today I couldn't even make it to a half hour. So not good for my workout regimen. Any Suggestions as to what I should eat or not eat prior to my 6:00 am swim?
