On The Bike Again

…after too long off it. 16 miles, riding in the hills near my house in Sunland on Sunday, took my pulse rate up to 163 beats per minute, almost 98% of my theoretical maximum (which, if you’re not too familiar with typical pulse meter readings, is more or less stunning). My breathing has been stellar […]

Half-Time Show: Forty-Two!

In 1985, I was trim and fit (not to mention 20 years younger). I was walking every night, riding my bike at lunch, and I was down to 179.5 pounds. I am over six feet tall, and that was a good, good weight. Let us fast-forward to 1999, about 14 years later. Somehow, I had […]

Oh, Ow…Why? (New Personal Trainer)

I’ve written before about the cardinal rule of being instructed by a physical therapist or personal trainer, and it’s this: people are naturally efficient, and they are particularly good at exercising the muscles that they normally use, and at not exercising the muscles that they don’t normally use. So, when a trainer tells you how […]

Part 9:  …Especially Fructose

(Back to Parts One, Two, Three, Four, Five, Six, Seven, or Eight) One piece of advice that you wouldn’t imagine to be controversial, at least, is to minimize your intake of sugar. But even here, the mainstream voice can surprise: the American Diabetes Association still to this day says that for diabetics, “Sucrose-containing foods can […]

Part 8: Insulin, High Blood Sugar, and Dementia

(Back to Parts One, Two, Three, Four, Five, Six, or Seven) By the 1990’s, researchers started reporting that heart disease and Alzheimer’s seemed to share risk factors: hypertension, atherosclerosis, and smoking were all associated with an increased risk of Alzheimer’s disease. The connection with insulin and high blood sugar is concrete: “Type 2 diabetics have […]

Part 7: Safety Second — Deficiency

(Back to Parts One, Two, Three, Four, Five, or Six) Will a low-carb diet lead to diseases of deficiency? It shouldn’t, because we don’t actually restrict the bulk of fruits and vegetables. Only refined sugar, flour, bread, potatoes, rice, beer, and those foods composed chiefly of these need be restricted. This leaves a rather large […]

Part 6: Safety First — Excess

(Back to Parts One, Two, Three, Four, or Five) Is a low-carb diet safe? A diet that is lower in carbohydrates is by necessity higher in protein and fat. And everybody knows that’s supposed to be trouble, right? After all, researchers have been focusing on dietary fat and cholesterol for a long, long time as […]

Part 5: Prescription

(Back to Parts One, Two, Three, or Four) Well, it’s pretty obvious what this has been leading up to, isn’t it? The only thing that can cause fat loss is a low insulin level, and to do that, you have to restrict carbohydrates. You can either do that by restricting total calories, or by restricting […]

Part 4: Insulin, Hunger and Satiety

(Back to Parts One, Two, or Three) Suppose you have some lab rats. If offered rat chow, they’ll eat until they’re satisfied, and then stop. But what, exactly, triggers that satisfied feeling? What makes a rat happy? What makes a rat hungry? Proponents of high-fiber diets claim that adding fiber to meals helps promote a […]
