Most of the low-carbers I know end up experimenting with intermittent fasting at some point in their...
What if a person secretes too much insulin in response to a glucose load? What if, for whatever reason (and there are dozens of possible culprits), a person’s cells are resistant to the effects of insulin? What if, to remove the same amount of glucose from the blood, a person secretes twice or thrice the amount of insulin? What happens when insulin stays elevated? Lipolysis is inhibited to an even greater degree. Body fat becomes even harder to burn. Susceptible brain, artery, and pancreatic cells are exposed to higher levels of blood sugar for longer. Muscle protein synthesis falls off a cliff. Glycogen is replenished at a diminished rate. And if cells are already full of glycogen and there’s nowhere else to put the glucose, it converts to fat for storage.
Obviously, we don’t want to be insulin resistant. We want to be insulin sensitive. Here are 10 nutrition-based actions.Read More
If you think of Type 2 diabetes as carbohydrate intolerance, the natural dietary response should be to restrict the offending dietary component. And when this occurs—when diabetic patients restrict carbs—their symptoms improve, often to a greater degree than diabetic patients on other diets. Keto restricts more carbs than even other low-carb diets, so on the face of things, keto seems great for diabetes.
Let’s take a closer look.Read More
It’s impossible to talk about using food as a drug without looking at the genuine neurological and hormonal impacts it has on the body. The fact is, certain foods affect us more like drugs than others.
With actual drug use, we’re not operating with innate satiation signaling. But with food, our bodies have a built-in system for telling us when to eat, how much to eat and when to stop.
In our paleolithic ancestors’ time, it worked great. Today, we’ve become our own saboteurs. We’ve known for years that sugary and processed foods (those that strategically combine sugar, salt and certain fats into a triple crown disaster) are intentionally designed to override our inherent satiation signals and hyper-trip our reward systems.Read More
Keto may not be for everyone, and low-carb is not the only way to eat well, but most would agree that people in the modern world tend to eat way too many carbohydrates—far more than their lifestyles and activity levels warrant. Along with some other big factors, excessive intake of refined carbohydrates is a major player in the modern epidemics of obesity, diabetes, heart disease, and other disorders. This is no longer controversial. Reducing carbs is a good move for most folks.
The majority of my readers are on some kind of low carb diet. Maybe they’re not fully keto. But they all tend to acknowledge the utility of limiting one’s carbs to only those they need. One of the more common questions I receive from this group concerns carb cycling—periodically adding more carbs to an otherwise low-carb diet.Read More
Most discussion of chronically-elevated insulin levels (hyperinsulinemia) and insulin resistance revolves around their relationship to bodyweight. This is unsurprising. Bodyweight’s what “sells tickets.” It’s why most people get interested in diet, health, fitness, and nutrition—to lose weight or avoid gaining it.
But improving insulin sensitivity and reducing fasting insulin levels have major ramifications for your health, longevity, and resistance to disease. And it’s not just because “weight gain is unhealthy.” Insulin itself, in excess, exerts seriously damaging effects. Today, I want to impress upon you the importance of controlling your insulin response by laying out some of the health problems that stem from not controlling it.Read More
For today’s edition of Dear Mark, I’m answering some questions about keto (hey, you folks keep asking!). First, is being on a ketogenic diet actually congruent with our ancestry? Is there historical precedent? Next, is bad breath really a reliable indication of being in ketosis? And finally, could going keto help treat the autoimmune disease lupus?
Let’s take a look:Read More
