Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...Tell Me More
Last week in my post about Washboard Abs on a High-Fat Diet, No Ab Workouts and No Cardio I got a number of questions regarding my diet. So here it is. I’d recommend everyone visiting FitDay and giving it a try. I know when I have clients send me their FitDay records, it’s usually an eye-opener.
As noted in the previous post I am getting well over 50% of my calories from fat and am right at 1 g protein/lb. I try to keep my carbs at 100 grams a day plus or minus a few. This keeps me in a predominantly fat-burning state without ever being ketogenic (in the strictest sense). This is an important concept. Low carb does not necessarily mean ketogenic, as some people seem to believe.
The above figures correspond with the following foods and serving sizes. Though the vegetables and meat choices often change from one day to the next it is very typical of my diet.
FitDay also keeps track of your micro-nutrient intake:
One notable thing here: Despite eating a diet largely based on nutrient rich vegetables, healthy fats and some fruit it is still possible to not meet RDA of some vitamins and minerals. In this particular case I came up short on Vitamin D and Calcium. This is precisely one of the reasons why I spend some time in the sun each day and why I choose to take a multi-vitamin supplement. Sometimes even a great diet won’t meet all of your needs.
