In reply to xplorer: What's the problem with having too many carbs, unless you understand that you won't understand how you should change things.
Why just a little amount of fat? Unless you are worried about heart disease, what's the problem with a highish amount of fat in your diet.
When I was running training a lot 60-70 miles a week and training for a BG and Lakeland 100 i read that my calorie intake should be 33% carbs, 33% protein and 33% fats, which improves endurance because your body gets used to using the fats for energy, which it will be doing in the race.
I found it really hard to get up to the 33% fat and expensive to get up to 33% protein. Like said above, eggs, tuna are good for protein. Avacado, cheese, nuts are good for fats.
Just be aware that because fat and protein has a higher calorie density than carbs, so it doesn't have to be 33% of your plate which is fat in terms of area.
