Unless you've been using steroids and/or have a history of heart conditions in your family, I don't believe that having a lot of muscles is a risk factor for heart problems. You gain muscles by working out, so while you were building up your muscles, you also built up your heart! Simply put, unless you notice any limiting factors during working out (like ...

BMI is best suited for analyzing populations, not individuals. A single person might carry more muscle than the average and a BMI calculation would label them as "obese". However, when calculated for thousands of people (which can be done with BMI since it's so quick/cheap/easy to measure), the fluctuations tend to average out, and BMI is accurate enough to ...

It's a simple measurement that provides an immediate idea of whether you're overweight, underweight, or neither. It's based on the idea that people who weigh significantly more or less than the average person of their height are probably not a healthy weight. That's true in most cases, not all, and again it has only ever been meant as a general guide. We ...

I'm not sure about the origin, but there was an interesting article in the local newspaper about the All Blacks (the New Zealand rugby team/world number one team) in which it was stated even the lightest member of the team was overweight (based on BMI), and four of the players were obese. As professional sportsman, these players are all very well built, ...

Here's a cool picture that I feel encompasses what the problem with BMI (or any calculation based mainly on weight) is: Muscles are "heavy" (i.e. their density is considerably larger than that of fat). Once you start adding even just a decent amount of muscle mass, you will become heavier and throw the BMI way off-balance. I think most bodybuilders fall at ...

BMI is a rough estimate that is easy to calculate about where you stand for health, however it can be very rough. People with a lot of muscle can easily be overweight or obese, however this does not mean that they're unhealthy. The problem is that it doesn't differentiate between fat and muscle. The metric was developed in the 1840's by Adolphe Quetlet in ...

Overweight is generally defined as having more body fat than is optimally healthy. - Wikipedia Being over recommended weight is not equivalent with being obese. It is important that you maintain some body fat (the U.S. military requires 3% to the best of my knowledge) in order to be healthy. The bad news is that just a few extra pounds of fat can ...

First, congratulations on your transformation. No matter how it is done, it is always an accomplishment. First, the obvious things you did right: Got rid of sugary drinks Added exercise Used the momentum of one good change begetting another (cleaning the flat, etc.). I don't have enough information to determine if the food was right, so instead I'll ...

Screening Tool: BMI is primarily a screening tool. It can be done quickly and easily with a simple a tape measure and a scale. The measurements are run thru a formula that gives you a number to determine where your measurements fall between an underweight to overweight chart. @Informaficker had given you a formula and chart. Here is another formula: BMI ...

I am taking most of the data from Wikipedia here, but most consider this common knowledge anyway. The BMI or Body Mass Index is calculated by dividing your weight in kilograms by your squared height in meters. BMI = kg / m² So for example if you weight 65kg and are 1.73m tall you would get: 65 / 1.73² = 21.7 This index is then matched to a table to ...

BMI isn't something you use to calculate your personal fitness, it is a statistical measurement and highly inaccurate for personal use. There are a lot of diets that 'speed diet' your weight down and don't care about muscle loss, what counts is the result on your scale to make them look efficient. Safe rates of weight loss are mostly determined by your fat ...

BMI itself is a lousy proxy for physical fitness - just ask weightlifters - and it has to be calibrated to the physical scale of adult human beings, so I can't see how it could properly apply to small children. It's better to use the standard height/weight charts to see where a given child falls compared to other children (i.e. in terms of percentile). ...

OK, now that I'm looking at the spreadsheet again, and the fact that this is a whole day's worth of food, I can make a few suggestions: Don't count lettuce in your daily calorie counts. It is mostly water, and useful as a filler if you get hungry in the middle of the day. You don't have enough protein, unless you only have 32kg of lean muscle mass. You ...

BMI is about as simple as it gets to give a measure that works for a lot of people. But you're absolutely right that it doesn't work for everyone. For someone who isn't fit, I would say the BMI works pretty accurately as a signal they need to do something or face medical problems. For someone who is fit, the BMI isn't useful. But you're already fit so don't ...

Medical Checkup The best way to convince your health insurance provider that you are in great shape is to show them the results of your physical exam showing that you pass with flying colors. Your medical doctor would be the one to determine whether or not you are healthy. BMI is a screening tool - NOT a diagnostic tool. As stated by the CDC: ...

You might have a fast metabolism but it would be very useful if you shared an example of your daily intake so we can see how much and what you eat. You should eat a lot of proteins and the right ammount of carbs and have enough sleep (at least 8 hours a day) in order to gain quality weight. When I started to train I went to the gym 4 times a week, each ...

I have not had a discussion with an insurance provider, or had the need to have that conversation. But, I have had similar conversations with similar, physically strong people with regards to BMI. I doubt any single person will change the health industry from using BMI as a guideline for insurance premiums. I do not work for an insurance provider, but if ...

There are some other ways to calculate body fat other than the weight to height ratio or measuring waist and hip circumference. 1) Bio-electrical Impedance. This method uses a machine to send a small electrical impulse through your body. You normally have to input your Age, Gender, Height, Weight, and Physical Activity Level. The more information you put ...
