12. Determining Body Mass Index(BMI) Body Mass Index provides a ratio between body weight and height and is quickly becoming the standard way that we define obesity. Federal guidelines suggest that we keep BMIs under 25. BMI 19-25 desirable; minimal and low risk Pay attention to diet, increased physical activity and lifestyle changes. BMI 26-29 increased health risk; moderate risk All of the preceding and a low calorie diet(800-1,200 calories daily) BMI 30-40 Obese; high and very high risk All of the preceding, drug therapy, and a very low calorie diet BMI over 40 Extremely Obese; extremely high risk All of the preceding and surgery

14. Other Tests Used to Determine Weight Electrical impedance is a quick and fairly accurate means of determining an individual’s percentage of body fat that uses electrodes attached to the wrists and ankles to determine the percentage electronically. Hydrostatic weighing is a method of measuring body fat by submerging an individual in water.

15. Weight Loss Vs Fat Loss Typical Diet with no aerobic exercise and strength training may result in fat loss of only 6-7 pounds but also a loss of 2-4 pounds of lean muscle tissue Ideally we want a fat loss without a loss of lean muscle tissue. Many dieting fads may lose 2-3 pounds per week, but the main problem is that they are losing lean muscle mass and not fat. When the weight is gained back the weight is fat not muscle Which will result an uneven fat to muscle ratio that is unhealthy for the body.
