There's research that's proved to my satisfaction that our guts extract most to all of the available calories in carbs, whole grain a little less so than processed grains, but still it's most.
Fats and proteins not so much, which means a calorie of bread does not equal a calorie of steak, as far as your intestines are concerned.
Keeping that in mind, I'm trying to get my carb intake down to 40% of my diet, and increase "good" unsaturated vegetable fats and lean meat, and trying to go up and up and up on my veggies.
My new strategy to do this includes cooking a lot of delicious low-oil chinese stir fry recipes, using all the traditional sauces, from a website I found,

Wish me luck! I'm on a mission to eat fewer carbs for life. It's hard, when you've been reared with the traditional American diet as your go-to method of cooking.
