Mark Sisson Is Not Afraid of Fat, Part 2

The Harvard School of Public Health has announced the results of a painstaking 20-year study: fat does not make you fat, or sick, or anything else we’ve been taught about fat. In fact, a high-fat, high-protein diet does not contribute to heart disease. This is a mammoth issue in health right now, but the debate has been building behind the scenes of the drug, medical and food industries since the 1940s. I’ll be addressing it frequently.

For now, bear in mind, I have to stress that I am talking good fats (fish, avocados, nuts and the like). This is not a license to gorge on bacon (though I don’t think saturated fat is the health monster it’s been made out to be).

For those who have a hankering for some clickativity, the article as printed in Time this week.

  1. Hi Mark.

    I read this piece with interest.

    I have a question related to heart disease and oil/fat consumption.

    If you have the time, please take a look at this interview with Dr Devi Shetty, a highly respected cardiologist.

    In the interview he states quite clearly, oil is bad for the heart. To maintain a healthy heart, avoid or reduce oil intake.



    What are the five thumb rules for a lay person in the matter of heart care?
    1. Diet: Less of carbohydrate, more of protein, less oil 2. Exercise: Half an hour’s walk, at least five days a week; avoid lifts and avoid sitting for a longtime 3. Quit smoking 4. Control weight 5. Control blood pressure and sugar

    Which is the best and worst food for the heart?
    Best food is fruits, worst is oil.

    Which oil is better – gingili, groundnut, sunflower, saffola, olive?
    All oils are bad; the so – called best oil company has the largest marketing budget.


    Dr Shetty also suggests eating Walnuts to control cholesterol. From what I have read in your posts, you suggest moderate Walnut consumption.

    I’d appreciate your views on the above points.


  2. I get it, fat is your friend! but how much should i eat if i am eating say, 100 veggie carbs a day?
