Meet Mark

What is Mediterranean Keto?

As I’ve written before, although most people’s lipid numbers improve across the board, some people get interesting cholesterol responses to Primal ketogenic diets. LDL skyrockets, even LDL particle number. The jury’s out on whether or not they indicate negative health concerns or if keto dieters are a special breed that hasn’t received enough study. (There may be a few genetic profiles, such as APOE4 carriers, that react differently to certain dietary inputs.) Either way some people just want their cholesterol numbers to look good in a conventional way. These days, whenever I run into someone in the real world with these or similar concerns, I tell them to try “Mediterranean keto.”

What is that, anyway?

Dear Mark: Collagen vs Whey Follow-Up

For today’s edition of Dear Mark, I’m answering questions from last week’s Collagen vs Whey post. You guys had a lot of questions, mostly about collagen, and I’m here to answer them. Can collagen help with plantar fasciitis? Should you take collagen and whey together in the same smoothie, or do they cancel each other out? If a person can’t have whey, is there an equivalent protein powder source? Is glycine a good replacement for collagen? What about liquid whey from raw milk—how does it compare to powdered whey? If I wanted to get my glycine from foods, what would I need to eat and how much of it?

Let’s find out:

Collagen vs. Whey: Which Protein is Best For Your Needs?

Collagen or whey. Which should you choose?

For years, collagen/gelatin was maligned by bodybuilding enthusiasts as an “incomplete protein” because it doesn’t contain all the essential amino acids, nor does it contribute directly to muscle protein synthesis.  There’s definitely truth to this. If you ate nothing but gelatin for your protein, you’d get sick real quick. That’s exactly what happened to dozens of people who tried the infamous “liquid protein diet” fad of the 70s and 80s, which relied heavily on a gelatin-based protein drink. Man—or woman—shall not live by collagen alone.

As for whey, it’s an extremely complete protein. It’s one of the most bioavailable protein sources around, a potent stimulator of anabolic processes and muscle protein synthesis. I consider it essential for people, especially older ones in whom protein metabolism has degraded, and for anyone who wants to boost their protein intake and get the most bang for their buck.

This said, which is best for your needs today? Let’s take a look….

Tips for Doing Keto Without Dairy

I love dairy. As a man of primarily Northern European descent, my ancestors have been consuming the stuff for thousands of years. It doesn’t give me any issues. You won’t find me chugging tall glasses of straight milk these days, but I’m a big believer in cream, cheese, yogurt, and kefir. Very nutrient-dense food if you can handle it. Lactase persistence? I practically have lactase insistence.

My favorable response to dairy makes keto especially easy. High-fat and fermented dairy is high in nutrients and low in digestible carbs (the bacteria consume most of the lactose). Cheese, cream, kefir, and yogurt all happen to be the most nutritious forms of dairy and the most keto-friendly. Many others getting into keto lean heavily on dairy. It just makes keto easier, especially if you’ve grown up eating dairy.

But globally my reaction to dairy is pretty rare, and that changes the keto landscape for most people.

8 Tips For Keto on a Budget

A criticism often leveled against the keto diet is that it’s more expensive than a “regular” (read: SAD) diet. There’s some truth to that. It does cost more to buy meat than ramen and beans. I personally spend more on groceries now than I did before finding Primal. Not only did I shift to buying different types of food, I also came to care more about food quality. I started choosing more pasture-raised meat and eggs, and more pesticide-free and organic produce and dairy.

However, my grocery bills haven’t changed noticeably since going keto. If you’re already eating Primally, your daily foods don’t have to change that much if you decide to try keto. You’ll remove some (okay, most) of the fruits and root veggies, and sub in more above-ground veggies and probably some healthy fats. It’s not a substantial overhaul. However, if you’re coming from a standard high-carb, lots-of-cheap-packaged-foods diet straight into Primal+keto, it can be a shock to the wallet.
