Glycemic Load and Glycemic Index may be important

Trina bought a book years ago on the P.A.C.E. workout.  I had skimmed it before, and never used it.  We watched a another great BBC show on exercise recently called "The Truth About Exercise".  Trina mentioned that the high intensity interval training (HIIT) concepts that researchers talked about working well in that show are similar to P.A.C.E concepts written by Dr. Sears.  I decided to get that book out and give it a browse/read yesterday.  I'm definitely convinced now that HIIT needs to be part of my fitness training.  P.A.C.E. has some great ideas on how to implement and keep fitness fresh using different intervals and calisthenics.  I think it will work nicely with the Alternate-Day Diet. 

Dr. Sears writes a chapter or two on nutrition, and likes the combination of low Glycemic Index (GI below 40) and low Glycemic Load ( GL below 10).  As Dr. Sears explains, Glycemic Index tells how fast a food will spike your blood sugar, and Glycemic Load goes a step further to say how much carbohydrate is in the food.  The book has a great table listing GI and GL values of different foods.  Foods that fall into these categories are most veggies, meat, nuts, most legumes, dairy, eggs (he calls the perfect protein source), and some fruit.

The low Glycemic Load and low Glycemic Index concept I believe complement the Alternate-Day Diet well.  I believe that I do better on fasting days when I have foods that are lower in Glycemic Load and Glycemic Index.  I will be focusing on this more in the weeks ahead to test if these ideas work as well together as I think they will.

On a separate subject, I weighed in this morning per Dr. Johnson's recommendation of the morning after a fasting day once per week, and lost a pound to 189 pounds.  I believe the body fat reading was 14.2%, which is down from 14.5%.  More importantly since weight loss is not a goal is that I feel pretty good on the diet.  My energy levels seem to be up, and some lingering aches seem to be improving.  Trina is happy, too.  We continue on with another fast day tomorrow.
