Dear Mark: 21-Day Challenge Rapid Fire Edition

For one of the 21-Day Challenge contests last week, you guys asked dozens of questions. Today, I’m answering a bunch of them in rapid fire style including how to get kids to eat more meat and veggies, how to get adults to eat greens, whether keto can coexist with high-carb, if it’s better to eat seasonally and many, many more. Don’t expect long, drawn-out answers. I’m answering quickly and succinctly. If you have any further questions after hearing the answers, toss ’em in the comment section. There will always be more Dear Marks down the line.

Let’s get to it:

The Definitive Guide to Using Your Recent Ancestry to Determine Your Optimal Diet

Go back 160,000 years and we all share a common ancestor: The emergence of the first Homo sapiens in East Africa. Since then, humans have spread across every environment imaginable and adapted to those environments. Much remains the same. We all breathe oxygen, require protein, produce insulin, oxidize fatty acids. But extended stays in unique environments have created genetic proclivities in different populations. For example, descendants of people who settled in high-altitude areas like the Himalayas, the Andes, and the Ethiopian highlands tend to show greater resistance to low-oxygen environments, while the Greenland Inuit show unique adaptations to cold environments, including increased activity of heat-stimulating brown fat. And among the island-dwellers of Sardinia, where the landscape constrained the amount of available food, there’s considerable evidence of positive selection for short stature.

What other differences exist, and how can we explore them to inform and improve our own diet and lifestyle choices?

8 Reasons Why Low-Carb Diets Actually Work

The popular story of how low-carb diets work goes something like this:

Reducing your carbohydrate intake lowers your insulin levels. Since insulin keeps fat locked into adipose tissue, lowering insulin can increase the amount of fat released to be burned for energy.

For the portion of the overweight/obese population with insulin resistance and chronically-elevated insulin levels, this is a fairly accurate description of why low-carb diets work so well. When you’re an insulin-resistant hyper responder in whom even a baked potato can cause elevated, protracted spikes in insulin that hamper fat-burning for long periods of time, or a person living under the backdrop of perpetually-elevated insulin, dropping the most insulinogenic foods can be your way out of obesity.

Dear Mark: Foods for a One-Year-Old, Vegan to Primal, and Low-Carb Failing Fibromyalgia

For today’s edition of Dear Mark, I’m answering three reader questions. The first comes from Chris, who’s a little worried his one-year-old isn’t eating a wide enough variety of foods. As it turns out, he doesn’t need to worry, though I do offer a few suggestions for foods to include or offer. Next, how should Verria, a long-time vegan, transition to Primal? Is there anything to watch out for? What physiological and psychological issues will Anita have to face and overcome? And finally, what tips do I have for a fibromyalgia patient whose condition hasn’t improved on a strict very low-carb, high-fat diet?

6 Hidden Superfoods You Probably Already Have in Your Pantry

I generally don’t subscribe to the idea of superfoods. While I’ll try your obscure Amazonian berry that spent a fortnight fermenting in a capybara’s colon, I won’t join your pyramid scheme to help sell it. I may very well add a teaspoon of gelatinized maca root to my smoothie, but I won’t claim it’s responsible for my great health. These foods are perfectly nutritious, contain impressive levels of some unique phytonutrients, and often have robust clinical support as inclusions in healthy diets. But c’mon: who’s regularly eating goji berries for $15 a pound? They’re not even that great.

I’m far more interested in the regular “superfoods.” The normal foods that we don’t necessarily consider super. The ones that are just there but have incredible health benefits just the same.

Dear Mark: Sugar in Blackstrap Molasses, Eating Cheat Foods All at Once or in Installments, and Healthy Pooping with a Fused Knee

For today’s edition of Dear Mark, I’m answering three questions. The first one concerns blackstrap molasses, a type of sugar I’ve suggested people eat for its rich mineral content. Does the value of the minerals outweigh the impact of its sugar content? Next, say you’ve got a slice of birthday cake you’re committed to eating. Is it better to eat it all at once or piece it out across multiple days? And third, how can someone who’s unable to squat obtain the benefits of squatting while pooping? In the absence of actual squatting, is there anything a person can do to smooth out the process?
