Body composition monitoring gives you an insight into key health indicators that will enable you to monitor the impact of changes to your lifestyle:

  • See the impact of a change in diet on the body to make sure you are dieting a healthy way
  • Fine-tune your fitness program by monitoring progress of muscle mass and BasalMetabolic Rate
  • Monitor the level of visceral fat, which has been linked as a possible risk factor for developing Type 2 diabetes a factor in heart disease.
  • Set a target for your physique and monitor your progress towards it.


Body Composition Monitors calculate your body composition using Bio-electrical Impedance Analysis (BIA). Safe,low-level electrical signals are passed through the body via the footpads on the monitor platform. It is easy for the signal to flow through fluids in the muscle and other body tissues but it meets resistance as it passes through body fat, as fat contains little fluid. This resistance is called impedance. The impedance readings are then entered into medically researched mathematical formulas to calculate your body composition. Some monitors are also equipped with an athlete mode for adults with athletic body types: this would be a person involved in intense physical activity of approximately 10 hours per week with a resting heart rate of 60 beats per minute or less. Individuals who have been an athlete for a number of years but current ly exercises less than 10 hours per week should also use athletic mode. Otherwise, activity levels are rated on a scale from 1 (sedentary) to 3 (active).


Your body water levels naturally fluctuate throughout the day and night. Any significant changes in body water may affect your body composition readings; for example, the body tends to be dehydrated after a long night sleep so if you take a reading first thing in the morning your weight will be lower and your body fat percentage higher. Eating large meals, drinking alcohol, menstruation, illness, exercising, and bathing may also cause variations in your hydration levels. Note: To get the most reliable reading it is important to obtain a body composition reading at a consistent time of day under consistent conditions.Taking a reading before a midday or evening meal is suggested .


Body fat percentage is the amount of body fat calculated as a proportion of your body weight. Reducing excess levels of body fat has been shown to reduce the risk of certain conditions such as high blood pressure, heart disease, diabetes and cancer.


Total Body Water Percentage (TBW%) is the total amount of fluid in a person’s body expressed as a percentage of their total weight. Water plays a vital role in many of the body’s processes and is found in every cell, tissue and organ . Maintaining a healthy total body water percentage will ensure the body functions efficiently and will reduce the risk of developing associated health problems. Your body water levels naturally fluctuate throughout the day and night. Your body tends to be dehydrated after a long night and there are differences in fluid distribution between day and  night. Eating large meals, drinking alcohol, menstruation, illness, exercising, and bathing may cause variations in your hydration levels. Your body water percentage reading should act as a guide and should not be used to specifically determine your absolute recommended total body water percentage. It is important to look for longterm changes in total body water percentage and maintain a consistent, healthy total body water percentage. Drinking a large quantity of water in one sitting will not instantly change your water level. In fact, it will increase your body fat reading due to the additional weight gain. Please monitor all readings over time to track the relative change. Every individual varies but as a guide the average TBW% ranges for a healthy adult are: Female: 45 to 60% and Male : 50 to 65% Note: The total body water percentage will tend to decrease as the percentage of body fat increases. A person with a high percentage of body fat may fall below the average body water percentage. As you lose body fat the total body water percentage should gradually move towards the typical range given above.


This feature indicates the rating of viscera l fat in you r body. Visceral fat is the fat that is i n the intern al abdominal cavity, surrounding the vital organs in the trunk (abdominal) area . Research shows that even if you r weight and body fat remains constant, as you get older the distribution of fat changes and is more likely to shift to the trunk area especially post menopause. Ensuring you have healthy levels of visceral fat may reduce the risk of certain diseases such as heart disease, high blood pressure, and the onset of type 2 diabetes. Tanita Body Composition Monitors will provide you with a visceral fat rating from 1·59.Rating from 1 ·12: I ndica tes you have a healthy level of visceral fat. Continue monitoring your rating to ensure that it stays with in the healthy range. Rating from 13 ·59: I ndica tes you have an excess level of visceral fat. Consider making changes in you r lifestyle possibly through diet changes or increasing exercise. Source: Data from Columbia University (New York) & Tanita Institute (Tokyo) Note: Even if you have a low body fat rate, you may have a high visceral fat level.

For medical diagnosis, consult a physician.


Your Basal Metabolic Rate(BMR) is the minimum level of energy your body needs when at rest to function effectively including your respiratory and circulatory organs, neural system, liver, kidneys, and other organs.You burn calories when sleeping. About 70% of calories consumed every day are used for your basal metabolism. In addition, energy is used when doing any kind of activity,however;the more vigorous the activity is the more calories are burned. This is because skeletal muscle (which accounts for approximately 40% of your body weight) acts as your metabolic engine and uses a large amount of energy. Your basal metabolism is greatly affected by the quantity of muscles you have, therefore increasing your muscle mass will help increase your basal metabolism. By studying healthy individuals, scientists have found that as people age, their metabolic rate changes.Basal metabolism rises as a child matures. After a peak at the age of 16 or 17, it typically starts to decrease gradually. Having a higher basal metabolism will increase the number of calories used and help to decrease the amount of body fat. A low basal metabolic rate will make it harder to lose body fat and overall weight.


“Daily Calorie Intake (DCI)” is the sum of calories for basal metabolism, daily activity metabolism (activities including daily household chores), and diet-induced thermogenes is (energy used in connection with digestion, absorption, metabolism, and other eating activities).It is an estimate of how many calories you can consume within the next 24 hours to maintain your cur rent weight.


This feature calculates your BMR and indicates the average age associated with that type of metabolism. If your BMR Age is higher than your actual age, it is an indication that you need to improve your metabolic rate.Increased exercise will build healthy muscle tissue, which w ill improve your metabolic age. You will obtain a reading between 12 and 90. Under 12 will be displayed as “12 ” and over 90 displayed as “90”.


This feature indicates the weight of muscle in your body.The muscle mass displayed includes the skeletal muscles, smooth muscles (such as cardiac and digestive muscles) and the water contained in these muscles. Muscles play an important role as they act as an engine in consuming energy.As your muscle mass increases, your energy consumption increases helping you reduce excess body fat levels and lose weight in a healthy way.


This feature indicates the amount of bone (bone mineral level,calcium or other minerals) in the body. Research has shown that exercise and the development of muscle tissue are related to stronger, healthier bones. While bone structure is unlikely to make noticeable changes in a short period, it is important that you develop and maintain healthy bones by having a balanced diet and plenty of exercise. People worried about bone disease should consult their physician.People who suffer from osteoporosis or low bone densities due to advanced age, young age, pregnancy, hormonal treatment or other causes, may not get accurate estimations of their bone mass.


This feature assesses your physique accord ing to the ratio of body fat and muscle mass in your body. As you become more active and reduce the amount of body fat, your physique rating will also change accordingly. Even though your weight may not change,your muscle mass and body fat levels may be changing making you healthier and at lower risk of certain diseases. Each person should set their own goal of which physique they would like and follow a diet and fitness program to meet that goal. *Normal Ranges for these calculations are found on the Body Composition Readings Chart provided for you at the time of your BIA. The exception is a normal range for “muscle mass”because this number reflects the WEIGHT (not percentage of body composition) of your combined skeletal and smooth muscles.
