Using The Glycemic Index for Ultimate Fat Burn
The News
If you read any publications that deal with fitness or weightloss, you've probably read something about the glycemic index this month. A new study has just reported that eating foods that are low on the glycemic index before exercising drastically improves the fat burn during your workouts.
What is the Glycimic Index?
The Glycemic Index shows how your body's sugar levels respond to certain foods using a rating of 0-100, with 100-the highest level-being pure glucose. Foods with high numbers, such as simple carbohydrates, will increase the body's sugar levels rapidly while foods that are low on the glycemic index, such as whole grains or legumes, will increase the body's sugar levels slowly over a longer period of time.
So pass on that Gatorade (glycemic index value of 78), coffee with sugar, juice, or soda before your workout and burn more fat!
Here's a sample article on the Glycemic Index and Fat Burning from Jan/Feb Muscle and Fitness Magazine Hers:
Use The Glycemic Index To Increase Fat-Burning
Eating a meal containing low-glycemic index (GI) carbohydrates before exercise may result in a higher rate of fat-burning during exercise, report Loughborough University rearchers in the American Journal of Clinical Nutrition.
In two trials, eight healthy, active women ate a test breakfast that provided 2 grams of carbohydrates per kilogram of bodyweight-one meal was low GI , the other high GI-three hours before the subjects ran at 65% VO2 max for an hour. During exercise, the estimated rate of fat-burning was greater in the subjects in the low GI trial than in subjects who ate the high GI breakfast.
Use It: Before you do cardio, consider having oatmeal or some tuna on a slice of whole wheat bread 3 hours before your workout.
