Sometimes folks who are interested in losing weight or getting healthier get so focused on the minutia of ”optimizing” their diet, supplements, exercise, and lifestyle that they gloss over the basics. This is a mistake. No matter your goal, you have to lay a good foundation before worrying about the finishing touches. When starting a keto diet, that means gradually reducing carbs to build a base of metabolic flexibility and get into ketosis. To be clear, you can slam your body into ketosis by dropping from several hundred grams of carbs per day, typical in a modern diet, straight to the very low carb intake required for keto. I don’t recommend it, though. For one thing, jumping from a high-carb diet into keto sets you up for the world of hurt known as keto flu. When you suddenly deprive your body of glucose, you can expect to experience headaches, lethargy, brain fog, and an inability to perform your typical workouts. Gradually reducing carbs gives your body the opportunity to upregulate its ability to burn fat for fuel, a necessary prerequisite of ketosis. Not for nothing, a gradual transition also gives the people in your life time to get on board. You might be excited about your big lifestyle change, but I hear all the time from people who are struggling because their partners, kids, or roommates aren’t exactly supportive of them tossing all the junk food and refusing to go through the drive-thru on the way home. Even if you’re already following a moderate-carb Primal way of eating, I still recommend taking the time to make your transition as seamless as possible. No matter where you’re starting, the best way to reach ketosis is to gradually and systematically reduce your carb intake. This is the same approach that I describe in The Keto Reset Diet, and it’s worked for the thousands of people who have participated in our Keto Month challenges. What Is Ketosis? Ketosis is a metabolic state in which your liver is making ketones, which are molecules that any mitochondria-containing cell can use for energy. Your brain and heart especially thrive on ketones. To get into ketosis, you must deplete liver glycogen (the glucose stored in your liver) and keep insulin levels low. Very-low-carb diets and fasting, or a combo of the two, will get you there. Glycogen-depleting exercise helps, too. Ketogenic (“ketone making”) diets are popular for everything from losing weight to lowering insulin and blood sugar to augmenting traditional cancer treatments. Inflammation is at the root of every chronic illness, and ketones are anti-inflammatory. They are also an efficient fuel source, and athletes across the sport spectrum are experimenting with using low-carb diets to burn fat and ketones during exercise. The Primal Blueprint qualifies as a low-carb eating style, especially in comparison to the high-carb Standard American Diet, simply by virtue of the fact that it eliminates the major sources of carbs in the typical modern diet: grains and sugar. The version of keto I recommend … Continue reading “How to Gradually Reduce Carbs to Reach Ketosis”
Read MorePotatoes get a bad rap in many different health and diet communities. The keto and low-carb crowd says they’re too high in carbohydrates and will spike your blood sugar. The paleo guys are against them because they are neolithic foods from the New World that our Paleolithic ancestors had no access to. The autoimmune diet communities eschew them because they have various plant toxins that can cause inflammation and trigger sensitive and vulnerable individuals, and the conventional “healthy diet” people recommend against potatoes because they’re “empty white carbs.”
Is this criticism warranted? Is it true that potatoes have no place in a healthy diet, or are potatoes actually healthy? How do potatoes fit into a Primal diet?
Let’s dig into the actual evidence.
Read MoreWhen the keto diet first skyrocketed in popularity in the late 2010s, it quickly gained a reputation as the “bacon and butter” diet. Vegetables might appear on one’s plate as a small side of spinach or, more likely, cauliflower masquerading as everything from rice to pizza crust to wings. By and large, the focus was on limiting consumption to “keto vegetables” while focusing mainly on increasing fat intake. (I’m talking mainstream keto, mind you, not the Primal Keto Reset approach.) This, as you’d expect, led to no end of pearl-clutching from mainstream medical professionals and the popular media, who quickly branded keto as a dangerous fad diet, a heart attack in the making. It was true that many early adopters of keto went hard on butter, cream, cheese, bacon, and other high-fat foods, probably as an understandable backlash against the low-fat diet dogma that dominated the previous four decades. Some people still do, I’m sure. However, I think most keto folks now understand that they cannot (or should not, anyway) live on butter alone. At least in more forward-thinking health circles, contemporary keto looks less bacon-and-butter and more like a lower-carb version of the Primal Blueprint way of eating, complete with bountiful salads and larger servings of protein. Personally, I’m all for keto eaters embracing a wide array of produce (keto-carnivore diets notwithstanding). At some point, though, the carb question comes into play. By definition, keto requires you to limit your carbohydrate intake to keep glucose and insulin low enough to facilitate ketogenesis. All vegetables contain carbohydrates, some more than others. You can’t eat unlimited amounts of vegetables, especially the higher-carb ones, if you want to stay in ketosis all the time. So how do you decide which ones are best? What Vegetables Are Best for Keto? In order to achieve ketosis, most people need to limit carbohydrate intake to a maximum of 30 to 50 grams per day. Hence, the best vegetables to include on a keto diet are the ones that deliver the most nutrients with the fewest carbs. That sounds straightforward, but in practice, it can be hard to know where to draw the line. The internet is rife with lists that sort foods into discrete “allowed on keto” and “not allowed on keto” categories. They mean well—and they do help simplify the often confusing transition from SAD eating to keto—but they lack nuance. No food will knock you out of ketosis in a single bite. There are no “bad” vegetables. There are only serving sizes and carbohydrate content and fiber. Why does fiber matter? Because fiber is not absorbed into the bloodstream and converted into glucose. It’s counted as a carbohydrate, but it does not contribute to the glucose-induced insulin spike you want to minimize on keto. Fiber, especially the soluble type, is mostly just food for your gut microbes. From a ketosis perspective, fiber is neutral. And in vegetables, especially the leafy and above-ground non-starchy varieties, much of their carb content is actually fiber, meaning their glucose/insulin impact … Continue reading “Keto-friendly Vegetables”
Read MoreI’ve long espoused a fairly low-carb lifestyle for optimal health, but “low-carb” means different things to different people.
For some, it means eating the fewest carbs possible, as in a strict carnivore diet or something more like carniflex, a meat-centric approach that strategically includes some plants.
For others, it means a keto or Atkins-style diet that restricts carb intake.
Some people don’t count carbs at all but still consider themselves “low-carb” because they eat mostly meat, eggs, and vegetables, and they limit things like grains, fruit, legumes, and added sugars. Sound familiar? That’s the classic Primal or paleo approach.
What all these low-carb folks have in common is that they need to decide what to eat day in and day out. Thinking about food all the time can become tedious, especially when you’re trying out a new way of eating and don’t know what’s “allowed.” It’s tempting to sort foods into discrete categories based on macronutrients (carbs, fat, protein) and quality (“good” versus “bad” foods) to reduce decision fatigue.
Read MoreGrains are fixtures of modern life. Pastrami on rye, spaghetti dinners, corn on the cob, birthday cake, apple pie, endless breadsticks, pizza parties, taco nights.
Studies about “heart-healthy whole grains” in the news. “AHA Approved” icons affixed to any concoction in the grocery store that contains a few grams of wheat—never mind all the sugar and seed oils.
Grains are “staples,” bread is the “staff of life,” and most people can’t imagine a meal without some type of grain on the table.
Yes, grains are solidly etched into our modern Western psyche—just not so much into our physiology. For the vast majority of human evolution, we were hunter-gatherers eating meats, nuts, bitter wild greens, regional veggies, tubers and roots, and fruits and berries. We ate what nature provided. If we ate any grains at all, they were wild and scarce—never staples.
Read MoreWell, does it?
We’re all going to be putting food in our bodies just about every day for the rest of our lives. Most of us will do it several times a day. We’ll chew it, send it down the esophagus into our stomach, and expose it to gastric juices and digestive enzymes. We’ll strip it of nutrients and send the excess down to the colon for dismissal, feeding resident gut bacteria along the way. The whole process should go smoothly. There shouldn’t be any pain or discomfort, bloating or constipation. Oh sure, nobody’s perfect, and there will be slow-downs or speed-ups from time to time, but in general a vital, fundamental process like digestion shouldn’t even register in our waking, conscious lives.
But sometimes it does.
