Glycemic Index: Good Carb Choices
A quick crash course on carbs:
• Carbs are the primary source of fuel for your muscles in the gym.
• Carbs provide energy, so muscle protein is not broken down.
• Some carbs raise blood sugar too much and shut off fat burning.
• Calories are a unit of measure of energy. In other words calories provide fuel that can be broken down to provide energy, or heat if burned (literally).
• There are ONLY 3 sources of calories in our diets: proteins, carbohydrates, and fats.
A quick crash course on the Glycemic Index:
• The Glycemic Index is a scale from zero to 100 that represents a relative rise in blood sugar levels two hours after consuming that food as compared to pure glucose (which has a Glycemic Index of 100).
• The higher the Glycemic Index, the faster blood sugar levels increase, and the greater the disruption of fat metabolism.
• High Glycemic Index foods are associated with junk foods and sweets and fruit juices.
• Diets high in high Glycemic Index Carbs are associated with weight gain and obesity.
The bottom line is that, ideally, we want to choose the vast majority of our carbs from the “slower acting / longer lasting” category for physical performance, muscle protection and optimal fat loss. Below is a list of carbs (and their specific Glycemic Index number) that fall into that category.
CARBOHYDRATES WITH A GLYCEMIC INDEX 40 – 55
Sweet potatoes 48
Brown rice 50
Whole wheat bread 49
CARBOHYDRATES with Glycemic Index 40 or less
(Note: all meats and fish have a GI of 0, which makes sense as they are not sources of carbohydrates)
Brussel Sprouts 16
Bell pepper 10
Green beans 15
Pinto Beans 39
Kidney Beans 29
Lima beans 31
Almond Milk 30
Milk (whole, fat-free) 31-37 (but high insulinic index)
Yogurt 33 (but high insulinic index)
Dried apricots 31
Almonds 0 – but are not a source of carbohydrates
Pecans 0 – but are not a source of carbohydrates
Walnuts 0 – but are not a source of carbohydrates
Spaghetti (protein-enriched) 27
