I hate to say it but people keep using BMI as a measure of obesity. BMI stands for Body Mass Index. Here is a link on how to calculate your
BMI. The formula is basically your weight divided by your height squared. In theory it is supposed to give you a ranking on how what percentage body fat you have. In reality this works fine for a normal person. Normal being what the formular expects. In reality it stinks. If you are fit but overweight then you may have a large amount of muscle (good) but your BMI might indicate you are morbidly obese. if you are light weight but do not have much muscle then your BMI will be low even though you are unhealthy. Think of a cancer patient wasting away; their muscles have atrophied and they have a great BMI. You would hardly call them healthy!
Take me. Now I have lost quite a bit of weight but my BMI says I am morbidly obese. I know I need to lose more fat. I need to improve my lean body mass (muscle, bone, organs) ratio to my body fat. Why does BMI fail me? I have a short leg inseam (29 inches). I am 5 feet 11 inches. I have a long torso. When I sit down on a plane my head is well above the seat back. I have very large calves and quads. Not fat legs but very muscular legs. Muscle is denser than fat. So the more muscle I have the worse my BMI will be! There is a trainer at the gym who is very muscular. He is a weight lifter. I have seen him without his shirt on in the locker room and I would be surprised if he has over 5% body fat. Yet, i am sure BMI says he is overweight. The guy looks very healthy and is a darn nice guy.
There are better measures. One measure is to do hydrostatic body fat testing. I get it done at Adventist health on 10123 SE market St. In Portland out by the 205 mall. It is very reasonable and accurate. You make an appointment, bring a towel, and a bathing suit. They have a locker rooms. You change into your bathing suite. She has you step on a scale. Then you climb into a pool of warm water. You sit in this PVC chair that is hanging from a rope. (attached to a scale) She tells you what to do and you are in complete control.(no reason to panic) You put your head underwater, exhale as much air as you can. She will tap on the pipe to tell you she got the measurement. remember you control your access to the surface so there is no reason to panic. She has you do this 4 or 5 times to get a consistent reading. Then you take a shower and get dressed. She gives you the results. The cost is about $35. it is well worth it. You can see if when you are losing or gaining weight if it is muscle or fat.
This method is much better than the skin fold test. I used to do that but as I lost weight it "said" that I was getting fatter. I was not as The Trainer and my Endocrinologist said, your fat is getting looser, more giggly because your body is getting ready to metabolize it. (burn that stuff off)
Another pet peeve of mine is the starvation diets. Often they give you soy protein and starve you. (800 to 1,000 calories a day). yes, you will lose weight. Unfortunately, soy protein is not as good for you as other proteins and can affect women's hormones, promoting fat stores. So you get lighter by losing muscle and gaining fat. Just the opposite of what you want! Your basal metabolic rate drops. (basal metabolic rate is how many calories you burn per day doing nothing) You end up not being able to stay on this deprivation diet and when you add a normal amount of food, your body doesn't need it and stores it for future diets. (FAT-> Famine Anticipation Tissue) You become skinny fat. But you have a great BMI!
Finally, I want to say something about motorized wheel chairs. If at all possible never get one. There are a small group of people where they are necessary and appropriate. Unfortunately, they have become very popular and you see very obese people in them. If they do not get up and try to never use them again they will die in that chair. I have a friend who is a nurse and she sees this all the time. The chair kills them. Those people need a lot of help and encouragement. They are not going to get out of the chair in one day. It is going to take months of hard work. So please do not misinterpret what I am saying as I think they are lazy bums. Not at all.
