Quick update. I am six weeks into an eight week experiment based primarily on Phinney and Volek’s excellent Art and Science of Low Carbohydrate Living. Really, it’s a moderate protein, low carb (zero), moderate to low fat diet. Yes, you read that right: moderate to low fat. No, I’m not afraid of fat! But, yes, my body has plenty of fat and therefore I don’t need to consume any for energy. (Supplementing fish oil occasionally when I’m not eating grass fed beef and lamb or wild fish). I’m using a scale, but I’m also using skin fold calipers. For additional context, I have a moderate to small frame with a large relatively muscular upper body and small hips. I tend to store fat in my chest and love handles areas. I am 5’8” and weighed 132 when I graduated from college in 1989. I weighed 168.4 when I started this diet. I am 50 years old and do high intensity weight training twice a week. So far, I’ve managed to increase my muscle mass by about five pounds — with a moderate decrease in training intensity -- while losing exactly 15 scale pounds as of this morning. Translated: I’ve lost 20 pounds of fat and water so far. My weight is now 163.4 and my waist has dropped from 33.5 to 31. I am feeling great and actually it seems I’m about, oh 12-15 years younger. Of course that’s a subjective thing. This is a great experience! Let me know if you’d like more details. Cheers. Jim Swayze www.fireholecanyon.com
