Fit and Healthy Lifestyle

One of the most revolutionary diet ideas to come along is something called the Zone, which was originated by Barry Sears, Ph.D. The Zone is based on the idea that we should return to the diets of ancient peoples—diets which stress fruits, vegetables, and meat. The diet does not deny people carbohydrates, but simply limits their use. Dieters are encouraged to sharply curtail their intake of pasta and potatoes. The Zone works according to a formula of 40/30/30, meaning 40 percent carbohydrates, 30 percent fat, and 30 percent protein.

There is a physiological basis to the Zone. Dr. Sears developed the diet in an effort to limit the amount of insulin in the body. This is because a large amount of insulin can lead to a build up of fat, causing obesity and other medical problems. People on the diet are encouraged to obtain their carbohydrates from fruits and vegetables and their fat from olive oil and other monounsaturated fats.

Heart diseases remain the leading cause of death and ill health in most of the modern world. High levels of cholesterol are responsible for this fact. High cholesterol levels cause the cholesterol to accumulate in the walls of arteries making them narrower and inhibiting blood flow to organs like the heart and brain.

Over time, the blockage grows, so much so that enough amount of oxygen does not reach the heart or other vital organs. The ultimate consequence is a heart attack or stroke. Reducing cholesterol in the blood is, therefore, the primary concern of any health-conscious person.

Standard Cholesterol Levels in Blood

The ideal level of total cholesterol in blood is under 200 mg/dL. Optimum concentration range of high density lipoprotein (HDL) is 60 t0 90 mg/dL, though it is ok for an HDL level to be at least over 40 mg/dL. Low density lipoprotein and triglycerides should each be less than 100 mg/dL. People with blood levels of cholesterol higher than these should seriously think about reducing cholesterol by dieting, exercise, medication, or a combination of these.

Many nonvegetarians wonder what drives vegetarians to give up meat and adopt an entirely different lifestyle. There is no single answer to this question. Nonvegetarians become vegetarians for a number of different reasons - some even for multiple reasons.

Most vegetarians claim that they became a vegetarian for one of three reasons.

The first reason, which most vegetarians claim, is that they have ethical problems with eating meat. Most disagree with how chickens are debeaked, forced to live in small cages, and are then slaughtered when they do not produce eggs fast enough.

Most vegetarians also disagree with the crowded and stressful environments animals are forced into; and the hormone-laden feed used to make them grow faster and produce more.

People who become vegetarians for this purpose often draw ethical boundaries in different spots, depending on their personal beliefs. For instance, some staunch vegans wont consume yeast, wear wool, or even eat certain vegetables, such as carrots, that require killing the plant to harvest.

On the opposite side of the spectrum, some vegetarians–sometimes referred to as pseudo-vegetarians–will actually eat fish and chicken on a regular basis.
