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
For today’s edition of Dear Mark, I’m responding to four reader comments. First up, if a person can’t eat eggs, doesn’t like liver, but really wants choline, can they just supplement? Second, are a couple handfuls of almonds too much omega-6 for the average person? What if they eat fish? Third, a new study claims to show that keto dieting tanks hepatic insulin sensitivity. What should we make of it? Are we giving ourselves type 2 diabetes by going keto? And fourth, I highlight a great approach to drinking alcohol (and living in general) from one of our readers.

For today’s edition of Dear Mark, I’m answering just one question from the comment section of last week’s omega-3 post.
It’s a short one, maybe one of the shortest reader questions ever, and it represents one of the few cut-and-dry stances in ancestral health. Humans are omnivores, seed oils are bad for you, no curls in the squat rack, and farmed salmon is toxic poison.
Right? Maybe not.Read More
It’s been a long time since I published the Definitive Guide to Fish Oils.
Oh sure, here and there I’ve cited some research supporting the beneficial effects of fish fat, but it almost goes without saying that omega-3s are important. Everyone knows it. Even the most curmudgeonly, conventional wisdom-spouting, statin script-writing, lifestyle modification-ignoring doc will tell you to take fish oil. And research in the last few years has not only continually confirmed the health advantages but illuminated new applications—and new physiological explanations—for their essential function in the body.
But what are those benefits, exactly? Why should we be eating fatty fish or, barring access to high quality edible marine life, taking fish oil supplements?Read More
After my recent post on keto for women, I got a lot of feedback. One of the most common themes: “But what about menopause?” I heard from dozens of women in both the comment section and in emails who were having trouble losing weight and dealing with the varied symptoms of menopause. Was keto the answer? Was Primal? Were they doing something wrong?
Rather than start with the assumption that going keto or Primal is the best way to deal with menopause, I figured I’d start from ground zero, drawing on the extensive scientific literature on diet and menopausal symptoms to see if I could arrive at some general trends and make recommendations.Read More
People go keto for many different reasons. Some want to get better at burning fat so they have a clean, reliable source of steady energy at all times. Some people are treating a neurodegenerative disease, or trying to prevent one from occurring in the first place. Others just want to lose body fat, take advantage of the cognitive effects of ketosis, or stop seizures. Those are all common reasons to go keto. Another reason people go keto is for the benefits to physical performance.Read More
For today’s edition of Dear Mark, I’m answering three questions. First, what are some less expensive sources of marine fat high in omega-3s? Is canned salmon a good, safe, effective option? Second, a reader is training hard, eating low-carb/keto, doing IF, and feels pretty good despite not losing or gaining any weight? What should she do? What could she be doing wrong? And third, should you go keto while nursing?
