Complex carbs can be viewed as either fibrous or starchy. Fibrous carbs include leafy and multi-color vegetables that could be found in any healthy salad. Starchy carbs include grains, rice, old-fashioned oatmeal, pasta, beans, yams, and sweet potatoes.
Fibrous carbs have no portion restrictions because they barely increase blood sugar and help stabilize insulin levels. There are also significant amounts of fiber in fibrous carbs. Imagine that!
Starchy carbs bring a little more caution to the table. We're constantly reminded that unrefined grains, brown rice, etc. are healthy because of slower digestion and a high fiber content. While this is true, starchy carbs ultimately break down into glucose (sugar) and too much will eventually promote fat storage...unless your primal training utilizes this glucose.
So, what have we learned here? Eat veggies all you want...at every meal. Eat starchy carbs in correct portions AND during times of higher energy requirements. This leads us into Nutrient Timing, which you will soon learn in great detail.
Make it a great day!
