Washboard abs on a high fat diet?

You are what you eat?

That is Mark, age 54. His diet works out at about 58% of calories from fat, not as high as some.....but certainly higher than many! Otherwise there is:

2,458 calories, 58% of which was from fat; 165 grams of protein (1 gram per pound of body weight) and 114 grams of carbs. Now some might say that eating less than 2500 calories is too low for a moderately active man, but there are two points to make here. First, I am never really hungry. On this Primal Blueprint eating style, I eat when I want to and stop when I no longer feel hungry. Pretty simple. If I skip meals, I don’t get light-headed or famished. I don’t ever feel like I need more calories or that I am missing out on anything or “sacrificing” some guilty pleasure. I get plenty of protein to spare muscle and add to protein turnover. I get plenty of fat for fuel – sometimes 65% of daily calories.

Second - and this goes to the heart of the Primal concept – when you eat fewer carbs, your body readily accesses dietary and stored fat for fuel. Even at 8% body fat, I still have 46,000 calories of stored fat, at least 25,000 of which is available to use as fuel at any time. Theoretically, you could walk 250 miles on that. It’s a beautiful thing when you direct gene expression to “want” to burn fat instead of always storing it. You certainly don’t need cardio to produce the full effect (you can if you want, within guidelines). As we often say here “80% of your results come from how you eat.” Conversely, eating more carbs drives up insulin, drives carbs towards fat storage, decreases fat-burning by prompting fat cells to hold on to stored fat and makes you hungrier for more carbs. I could burn some or most of all that off again by doing tons of cardio, but that only makes me hungrier for more carbs and perpetuates the cycle. It’s like digging a hole to put the ladder in to wash the basement windows.

Sounds like what Peter is telling us here and here.....
