I asked my coach about Doing IP and training for a marathon and he said I had a couple of options.
1. Gradually Phase out of IP and focus on complex carbs and good protein sources for my increased nutritional/physical needs
2. Stay on IP plan but add the protein needed to not lose muscle during the intense endurance runs. He figured out I need about 100g of protein total per day bases on my body's lean muscle mass. This means adding a protein supplement at breakfast and lunch (with IP or with real protein foods such as tuna and hard boiled eggs) in addition to having protein within 45 min. of completing my work out. He gave me the actual written protocol.
3. Stay on current phase 1 IP plan and start jogging, closely monitoring how I feel for at least a week and report back to him.
I am excited about starting because this will further increase my fat/weight/inches loss as well as help me train for my fastest marathon ever since I will be that much lighter.
I am thankful for this site and all of you who post such encouraging and informative things....


That is so awesome... I am a little in awe of you now. I am about the same height/weight as you right now and I can't imagine training for a marathon. How inspiring!
