Neither the BMI nor the Body Fat Percentage, taken individually, gives the complete picture of your health. For example, bodybuilders often have high BMI (considered obese) but low Body Fat Percentage (considered healthy). The BMI, in this case, does not take into account that the extra weight is from muscles and water but not fat. Conversely, a very thin person may have low Body Fat Percentage (considered healthy) but also lower-than-accepted BMI (considered unhealthy). This means that the person is still at risk health-wise, despite the low Body Fat Percentage. Consult your physician before you begin a new diet or exercise program. BODY MASS INDEX What is Body Mass Index (BMI)? Body mass index (BMI) is a widely used international standard that measures height to weight ratio to determine obesity. BMI is expressed by the following terms: BMI = Body weight (kg) [Body height (m)]2 The BMI is only a general indicator of your health level. As such, accuracies may vary depending on your body type and composition. Consult your physician to find out more about your current health. Refer to WEIGHT CONVERSION TABLE to convert between weight units. How to Interpret BMI Use the resulting BMI value with the chart below to determine your current level of health:
How the Body Fat Monitor Works
When you step on the scale, a weight measurement is taken. The GR101 can also help you to automatically calculate your Body mass index (BMI) and Body Fat Percentage, two internationally accepted indicators of health and obesity levels. Weight alone is not a good enough indicator of health because it does not differentiate between muscles, tissues, bones, and fat. As such, when a person loses weight, it may be a result of the loss of muscles or body water but not fat. In order to better understand your body composition and current health level, both the BMI and Body Fat Percentage should be observed.
Asians have a separate BMI range due to their different body composition. Health BMI Description Indication Range Less Your body Underthan weight is weight 20.0 currently lower than average. Work toward healthy, regular *Asian food intake BMI: and exercise Less routine to than build up your 18.5 health to recommended levels. 20.0 Your health Recom 25.0 is at the mended recommended level.

BMI should not be used as a guideline for health risks for the following groups: Group Children and teenagers Athletes and bodybuilders Reason BMI ranges are only based on adult heights. BMI does not differentiate between fat and muscle, thus making it inaccurate for persons with high muscle volumes. This group generates naturally high fat reserves as part of the pregnancy.

BODY FAT PERCENTAGE What is Body Fat Percentage? Body Fat Percentage is a measurement of the total percentage of fat in your body. For example, if you weigh 70 kg and your Body Fat Percentage is 15%, then you are retaining 10.5 kg of fat. The remaining weight is composed of muscles, bones, tissues, and water weight.
Among overweight people, it is excess fat and not weight alone that carries health risks. Since the body comprises elements of varying densities, weight or BMI cannot fully measure exactly how much excess fat a person carries. For example, two people of the same weight and BMI may have big differences in body composition. One may carry excess fat while the other carry acceptable level of fat needed to regulate the body. As such, a Body Fat Percentage measurement is an effective assessment of your current health level. Essential fat is necessary for bodily functions, since it helps to maintain body temperature an insulate organs and tissues. How Body Fat is Measured The GR101 uses the method of Bioelectrical Impedance Analysis (BIA) to measure body fat. This method is completely safe, and is widely used in the medical field. The principle of BIA is as follows: GR101 sends a low, harmless electrical signal through your body that flows freely through fluids but not fat. As such, the machine measures the opposition to the signal and uses this to calculate the body fat percentage (along with the persons age, height, and weight).
How to Interpret Body Fat Percentage Use the resulting Body Fat Percentage value with the chart below to determine your current level of health: ADULT MEN Body Fat Level Very High High Normal Low Very Low Body Fat Level Very High High Normal Low Very Low Age Group in Years < 30 > 28% 22 28% 11 21% 610% <6% 3039 > 29% 23 29% 12 22% 711% <7% 4049 > 30% 24 30% 13 23% 812% <8% > 49 > 31% 25 31% 14 24% 913% <9%

Body Fat Standard Very High
Reason Percent fat at this level indicates the person is seriously obese to a degree that this can have adverse health consequences. Maintaining this level of fat for a long period of time places the person at risk of hypertension, heart disease, and diabetes. Consult your doctor on a long-term weight loss and exercise program. It is likely that the person is obese. Careful implementation and monitoring of diet and exercise is recommended. This is the ideal level of body fat for the average person. For athletes, this is a desirable level of body fat. For regular persons, a regular diet should be considered to improve the balance of body composition. The level of body fat is too low. Consult a physician for advice.

How Body Fat Percentage Fluctuates It is recommended that you choose a time slot to measure body fat and then monitor it regularly at the same condition. Ideally, body hydration level is most stable during late afternoon, right before dinner. Please note the many factors may alter an individuals body fat reading, including alcohol consumption, taking a bath or exercising, waking up, eating, fever and illnesses. BODY WATER What is Body Water? Total Body Water is the amount of water retained in the body, and comprises between 50%-70% of the total body weight. Generally, men tend to have higher water weight than woman due to a greater amount of muscle. Athletes also tend to have 5-8% more Total Body Water

due to more muscle mass. Staying within the proper Body Water range is very important in order to stay healthy. It plays an important role in the regulation of body temperature, removal of waste from the body, cell metabolism, and keeping skin and tissues moist. How to Interpret Body Water Levels Use the resulting Body Water Percentage value with the chart below to determine your current level of body water: Body Water Level High Slightly High Normal Slightly Low Low Body Water Level High Slightly High Normal Slightly Low Low Male >70% 65 - 70% 53 - 65% 48 - 53% <48% Advice Consult your physician for advice. Observe your nromal water intake. This is the ideal level of body water. Drink more water to keep proper hydration. Consult your physician for advice. Female >65% 60 - 65% 50 - 60% 48 - 50% <48%

HOW THE BODY WEIGHT MONITOR WORKS BRIEF DESCRIPTION When you step on the Monitor, a weight measurement is taken. The Monitor can also help you to automatically calculate your Body mass index (BMI) and Body Fat Index, two internationally accepted indicators of health and obesity levels. Weight alone is not a good enough indicator of health because it does not differentiate between muscles, tissues, bones, and fat. As such, when a person loses weight, it may be a result of the loss of muscles or body water but not fat. In order to better understand your body composition and current health level, both the BMI and Body Fat Index should be observed. Neither the BMI nor the Body Fat Index, taken individually, gives the complete picture of your health. For example, bodybuilders often have high BMI (considered obese) but low Body Fat Index (considered healthy). The BMI, in this case, does not take into account that the extra weight is from muscles and water but not fat. Conversely, a very thin person may have low Body Fat Index (considered healthy) but also lower-than-accepted BMI (considered unhealthy). This means that the person is still at risk health-wise, despite the low Body Fat Index. NOTE Consult your physician before you begin a new diet or exercise program.

BODY MASS INDEX What is Body Mass Index (BMI)? Body mass index (BMI) is a widely used international standard that measures weight to height ratio to determine obesity. BMI is expressed by the following terms: BMI = Body weight (kg) [Body height (m)]2
The BMI is only a general indicator of your health level. As such, accuracies may vary depending on your body type and composition. Consult your physician to find out more about your current health. NOTE To convert pounds or stone pounds to kilograms, and inches to meters, refer to the conversion reference on page 13. How to Interpret BMI Use the resulting BMI value with the chart below to determine your current level of health: NOTE Asians have a separate BMI range due to their different body composition.
Health Indication Underweight
BMI Range Less than 20.0* * Asian BMI: Less than 18.5

Recommended

20.0 25.0* * Asian BMI: 18.5 23.0
Description Your body weight is currently lower than average. Work toward healthy, regular food intake and exercise routine to build up your health to recommended levels. Your health is at the recommended level. Maintain a balanced diet and exercise to keep your current level of health. Your body weight may be above normal. Increase your exercise and work out a diet plan to lower your risk for serious illness. At this level, you may be at risk for heart disease, high blood pressure, and other illnesses. Consult with your doctor to develop a proper health and fitness plan.

Overweight

25.1 29.9* * Asian BMI: 23.0 29.9
30.0 or greater* * Asian BMI: 30.0 or greater
NOTE BMI should not be used as a guideline for health risks for the following groups: Group Children and teenagers Athletes and bodybuilders Pregnant or nursing women People over the age of 65 Reason BMI ranges are only based on adult heights. BMI does not differentiate between fat and muscle, thus making it inaccurate for persons with high muscle volumes. This group generates naturally high fat reserves as part of the pregnancy. Fat reserves naturally tend to be higher with older persons. 5
