1. Ectomorph: These are people who are lean and long with problems gaining muscle.
2. Endomorph: People in this category are big, they have a high body fat percentage, pear shaped and can store fat.
3. Mesomorph: Muscular and well-built, with high metabolism and responsive muscular cells, they have no problem putting on muscle.

So these are the 3 body types that people fall into all around the world, but people do not just fall into 1 category, usually they will fall into a combination of all 3. Because we are all different and unique we fall into all 3 by percentages.I am 63% Endomorph, 38% Mesomorph and 0% Ectomorph. A combination of all 3, and depending on how much muscle weight I put on I switch between Endomorph and Mesomorph but will never be Ectomorph.

People all across America go in for their yearly physicals and are told they are obese because their BMI and they need to lose weight immediately. Now as Americans the doctor is correct we do need to lose some weight but to follow the BMI would be ridiculous. Changes have to be made so that people can get a firm handle on how much fat they need to lose. You see, our body weight has skin, fat water, bones, muscles and organs to name a few. When we as people want to lose weight what we need to lose is body fat. And to loose body fat you need to test your actual body fat and use this as your foundation. I placed the calculations that I use so that I can achieve my goal of 18% body fat.
