The artery wall consists of three different layers. If the reader can picture a garden hose as representing the artery, it presents an innermost layer called the intima, a middle layer called the media, and an outer layer called the serosa.
Is fat necessary? That’s like asking “Is crime necessary?” or “Is it necessary to be fat?” The action of asking by itself already seems bad, like asking “How often do you beat your wife?” Of course, to all of these questions the answer is no.
The large quantity of fat eaten everyday in the United States and Europe usually come in the form of butter, eggs, whole milk, cream, meat, fish and poultry fats, and cheese in various combinations. Fat, at 9 calories per gram, holds over twice the amount of calories than protein or carbohydrate, which yield four calories each per gram. We will discuss further how over-consumption of fats can lead to a shortened lifespan, caused by heart attacks and strokes, obesity, and other diseases.
Why is the epidemic of heart disease particularly strong in the U.S.A.? If you are the average American, your diet is probably unbalanced and is very likely to lead you towards obesity, regardless of whether you know it or not. Drs. Louis Katz and J. Stamler, prominent researchers in this field, called it “a pernicious combination of over-nutrition and under-nutrition -excessive in calories, carbohydrates, lipids and salt; and frequently substandard in certain critically important amino acids, minerals and vitamins.” This makes sense, since the study of nutrition, which is relatively new to the medical field, has focused almost entirely on not having enough nutrition until recent years. People have been encouraged to “eat the right foods” and to provide plenty of meat, eggs, milk, and cheese for their children.
1. Watch how much fat is in your diet. Each fat gram contains 9 calories so by reading the total calories on a food and knowing the quantity of fat, you can estimate the fat percentage in the food. Sometimes the calories due to fat is on the label too, and this should not exceed 30% of the total calories.
One of the greatest factors influential in the current epidemic of heart attacks has unquestionably been the startling increase in fat intake. In the United States alone, the fat content of our diet has just about doubled in recent times. Where fat formerly constituted some 15 to 20 percent of our meals 50 years ago, it now has jumped to 30 and 40 per cent or more.
1. If you are unable to run, try walking. 15 minutes of fast-paced walking a day is enough to keep most people in decent shape.
1. Eat as many vegetables as you can. Vegetables are the ideal food when it comes to losing pounds. There are plenty of vegetables to choose from, and the leafy green vegetables are the best variety. A great way to incorporate vegetables is to eat a salad everyday – it’s tasty, easy to prepare, and there are plenty of ways to mix it up.
In this article I want to compare traditional long, slow cardio with interval training for fat loss. From a fat loss standpoint, the more calories you burn, the better. Let’s see how good long, slow cardio and interval training are at burning calories.
