  • Body Mass Index (BMI)

    The body mass index is a way of assessing whether a person is in the healthy weight range for their height. BMI is calculated by dividing your weight in kg by your height in metres square (BMI = kg/m2). People with a BMI between 18-25 kg/m2 are considered a healthy weight, 25-30 kg/m2 overweight and over 30 kg/m2 obese.

  • Basal Metabolic Rate (BMR)

    Basal Metabolic Rate (BMR) is the rate at which the body uses energy at rest. This energy is needed for the maintenance of basic body functions such as breathing,maintaining a normal heart rate and body temperature. BMR varies according to body-weight, gender, growth rate and age.

  • Balanced diet

    A balanced diet contains a variety of food in appropriate amounts that provides all the essential nutrients and energy required for good health. Variety and moderate portions are the key to a balanced diet.

  • Blood pressure

    Blood pressure is one of the important vital signs; it refers to the pressure exerted upon the walls of the arteries as the heart pumps blood throughout the body. Blood pressure is indicated in terms of systolic pressure over diastolic pressure, for example a normal blood pressure is 120/80 mmHg. If the value is higher than 140/90 mmHg,then it is considered high, and a consistently high blood pressure increases the risk of heart failure, heart attacks, strokes and kidney failure.
