Endless diets and other digestive treatments were proposed. But essentially, they all followed the oldest idea—that the digestive process was mainly mechanical.

(The dairy people hardly let us forget.) But most of us tend to liken the human skeleton to the steel framework of a building—solid, fixed, and constructed but once in the original building process. Actually, our bones are constantly changing and interacting with the rest of the body.

As we’re freed from the spell of food rumor and fantasy, we can confidently choose from the wonderful variety of foods—fresh and processed—available in the marketplace.

Smoking reduces the amount of oxygen the blood can carry, causes constriction of the blood vessels and damage to the vessel lining, raises blood pressure, and increases the risk of blood clots.

Keep in mind that when an activity is strenuous, it’s hard to sustain that activity for long —we have to stop to “catch our breath.” One might spend an hour “working out,” but most of that time may be spent resting between lifts and strolling from one piece of exercise equipment to the next.

Keeping those pounds off is another matter. Most fail in the long-run because we go back to eating the way we did before, and our bodies compensate somewhat to taking in fewer calories and weighing less. Also, when we start a diet, we’re motivated and focused, and lose weight. Even the most creative diet plans aren’t all that creative because they use tried-and-true ways to get us to eat less:

Because atherosclerosis develops over many years, even a modest reduction in its rate of progression can delay significantly the onset of symptoms. For example, dietary changes beginning in young adulthood to lower LDL-cholesterol levels could possibly slow the progression of atherosclerosis so that a heart attack or stroke that might have occurred at age 65 might be delayed to age 80 or older.
