Meet Mark

Electrolytes and Keto: Why They Matter for the Transition

The one piece of advice all newcomers to the ketogenic diet receive is to “get enough electrolytes.” It doesn’t matter what flavor of keto diet you’re talking about—paleo, carnivore, Primal, standard, clinical, mainstream, salami-and-cream-cheese. They all mention the importance of getting your electrolytes, particularly during the transition from a higher-carb diet.

I’ve said it. I say it. It really is important. Heck, a major part of the much-maligned “keto flu” can be directly attributed to inadequate intake of sodium, potassium, and magnesium. Oftentimes, increasing your electrolytes stops the flu from happening in the first place.

Why, though?

The Keto Carb Threshold: What Constitutes a “Keto” Meal?

How many carbs can you eat in a sitting and still “stay keto”? What constitutes a “keto meal”?

I’ve gotten many questions about this topic.

First of all, let’s get this out of the way: Keto is not a religion that punishes heretics with eternal damnation (or eternal reliance on exogenous sugar for energy). This post is not intended to make people feel guilty for eating five grams of carbs over the” limit.” It’s not even intended to set a hard limit in stone. It’s simply to provide people who care about this sort of thing a basic, admittedly rough, guideline for staying below the keto carb threshold within meals throughout the day.

Keto Convenience Foods: What To Try (and What To Skip)

If you read any of those “10 Reasons Keto is the Worst” articles out there, the common anti-keto argument you’ll see is that it’s too hard. The premise: keto must be unsustainable because eating meat, eggs, avocados, veggies, nuts, coconut, etc. is just too arduous long term. I’m sure you can guess how I feel about that.

Nonetheless, when you switch from a SAD diet to Primal or Primal-keto it genuinely becomes harder to grab convenience foods. It’s not that you can’t. The selection of packaged foods being marketed to keto folks has exploded in the past year or so. Rather, your growing awareness of ingredient quality, coupled with a desire to control your food and nutrition, makes it feel harder… and probably less desirable.

Is Keto Cheating Unhealthy?

A couple months ago, a study came out that seemed to show that cheating on your keto diet with a high-carb meal opened you up to severe blood vessel damage. Nine healthy, normal weight adults followed a keto diet (70% fat, 20% protein, 10% carbs). Then they ate a high-carb “cheat meal,” measured their blood sugar, and measured their endothelial microparticles—a marker of damage to the endothelial lining and potential harbinger of impaired vascular function. Their blood sugar went way up, and so did their endothelial microparticle count, leading researchers to conclude that keto dieting makes people more susceptible to hyperglycemia-induced endothelial damage.

So, is keto cheating unhealthy? Let’s take a closer look….

Keto and the Menstrual Cycle: Is There Reason To Worry?

It seems every “keto for women” forum abounds with stories about menstrual cycles gone wild in the first few months of keto. Irregular cycles, breakthrough bleeding, and periods lasting much longer than normal are common complaints. Sometimes these stories are cited as evidence that keto isn’t good for women, at least not premenopausal women, and that we need carbs for healthy hormones. Yet, many women don’t notice any changes in their menstrual cycles at all, while others report improvement in PMS symptoms and cycle regularity from the get-go.

What gives? Why do some women’s cycles apparently become wacky when they start keto, while others feel like keto is the key to period bliss? Can keto “mess up” the menstrual cycle?

13 Keto-Friendly Fiber Foods

While some keto or low-carb proponents claim fiber is useless at best and actively harmful at worst, I come down on the side that says fiber is probably helpful for most people. Some folks have persistently better responses to low- or no-fiber keto diets, and I won’t argue with that—I’ve seen it happen and I’ve read the studies where de-emphasizing fiber can actually improve constipation, for example.

I’ll just say that I have an opposite reaction, and, most importantly, I love eating a variety of plant foods that also happen to contain a ton of great nutrients in addition to fiber.

12 Favorite Keto Blogs

With the explosion of keto, there’s an ever growing constant stream of new information about the significant benefits, supposed risks, and varying “rules” for how to adopt a keto diet. As with most things, it’s easy to get sucked into information overload. (And that doesn’t even take into account the hype that unfortunately gets distributed like wildfire around the Internet.) You want sources you can count on for facts, reason, and utility. While there are many resources out there, here are twelve sites I enjoy for intelligent commentary, sound science, and useful ideas. They may not be the biggest, but over time they’ve become my personal favorites.
