Meet Mark

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.

Dear Mark: Low Energy on Primal Challenge

Dear Mark,

I’m finding that I have low levels of energy in the evenings only. Could this be because my body is still adapting to primal living and adjusting to less carbohydrate intake? How long does this usually last? I’m also finding that after my sessions of intense Muay Thai training, I don’t have the energy the next day to do much of anything regarding exercise. (My Muay Thai routine includes two hours of jumping rope, calisthenics, ab work, sparring, focus mitt work and pad work in 92-93 degree heat three days a week.) Any suggestions?

Watermelon a Natural Viagra?

A study by researchers at the Fruit and Vegetable Improvement Center at Texas A&M University suggests that watermelon may act as a natural version of the erectile dysfunction (ED) drug Viagra.

The Food of Lust?

While researchers have always been aware of watermelon’s high citruline content, studies had suggested that the bulk of the chemical was in the less-commonly eaten rind. However, the latest research from Dr. Bhimu Patil suggests that there are also high concentrations in the more tasty flesh of the fruit.

Is All Chocolate Created Equal?

My wife and I tend to receive a lot of chocolate, usually as holiday or dinner party gifts. Friends and business associates know we’re not dessert people but that we indulge in chocolate and red wine on occasion (i.e. those Sensible Vices). As a result, I’ve gotten to try a lot of the best chocolates out there (as well as a few duds). My wife and I each have our running lists of favorites. Hers has a couple Belgian varieties as well as some quality stateside organics. As for me, the more bitter the better. Green and Black’s makes an 85% that I consider kind of my “staple” choice, but there are a lot of good ones out there.

The Context of Calories

200 Calories is 200 Calories. Right?

“What’s that in the road ahead?”

vs.

“What’s that in the road!? A head!?”

Context is important.

Many people think weight loss is simply about cutting calories. But context counts here, too. Calories do have context and that’s what I want to explore today. Is a calorie from fat the same as a calorie from protein or carbohydrate? Depends on the context. Does day-to-day calorie monitoring make any difference if your week-to-week weight and energy expenditure are dialed in? Maybe not.
