Blood pressure is an important and vital health indicator. High blood pressure (arterial hypertension) may cause changes to blood vessels, resulting in Atherosclerosis, also known as “hardening of the arteries”. Atherosclerosis is the leading cause of stroke, heart attacks and peripheral vascular disease.
Too much dietary fat causes many health problems. However, it is important to have some fat in your diet; about 20 to 35 percent of your calories should come from a variety and balance of healthy fats (polyunsaturated and monounsaturated fats).
Healthy fats are used by your body in several ways:
1. Fat provides a highly-concentrated form of energy.
2. Fat enables your body to transport, store and absorb the fat-soluble vitamins A, D, E and K. An absence of fat may mean a deficiency in these vitamins.
3. Fat provides insulation and a protective cover for vital organs.
4. Essential fatty acids from omega-3 and omega-6 fats cannot be made by your body, and therefore they must be supplied through your diet. .
Basal Metabolic Rate (BMR)
is the amount of energy you need while resting in a temperate environment during the post-absorptive state, or when your digestive system is inactive. In such a state, your energy will be used only to maintain your vital organs, which include the heart, lungs, kidneys, the nervous system, intestines, liver, lungs, sex organs, muscles, and skin. The BMR decreases with age and increases with muscle mass.
The BMR is measured under very restrictive circumstances while awake. An accurate BMR measurement requires that a person's sympathetic nervous system is inactive, which means the person must be completely rested. Basal metabolism is usually the largest component of a person's total caloric needs. The daily calorie needs is the BMR value multiplied by a factor with a value between 1.2 and 1.9, depending on the activity level.
In most situations, the BMR is estimated with equations summarized from statistical data. The most commonly used one is the Mifflin - St Jeor equation:
BMR = 10 * weight(kg) + 6.25 * height(cm) - 5 * age(y) + 5 (man)
BMR = 10 * weight(kg) + 6.25 * height(cm) - 5 * age(y) - 161 (woman)
Body Mass Index (BMI)
is a measurement of your body weight based on your height and weight. Although your BMI does not actually "measure" your percentage of body fat, it is a useful tool to estimate a healthy body weight based on your height. Due to its ease of measurement and calculation, it is the most widely used diagnostic indicator to identify a person's optimal weight depending on his height. Your BMI "number" will inform you if you are underweight, of normal weight, overweight, or obese. However, due to the wide variety of body types, the distribution of muscle and bone mass, etc., it is not appropriate to use this as the only or final indication for diagnosis.
The formulas to calculate BMI based on two of the most commonly used unit systems:
BMI = weight(kg)/height2(m2) (Metric Units)
BMI = 703·weight(lb)/height2(in2) (U.S. Units)

The Calorie Calculator can be used to estimate the calories you need to consume each day. This calculator can also provide some simple guideline if you want to gain or lose weight. Use the "metric units" tab if you are more comfortable with the international standard metric units.
This calculator gives out the healthy body weight range based on the body height for both man and women. This calculator works best for adults of age 18 or older.
Cellular respiration is the set of the metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products.
