Another way to check your weight is to calculate your Body Mass Index or BMI. Your BMI is a ratio or comparison of your height and weight expressed in a number. To find out your BMI you need to divide your weight (measured in kg) by your height (measured in metres) squared.

The accepted definitions of weight categories by BMI are: Underweight less than 20 Healthy weight between 20 25 Overweight between 25 30 Obese - greater than 30 These BMI values only apply to adults aged 18 years and over and are based on studies of Caucasian populations. Therefore, they are not applicable to children and adolescents and they may not be appropriate for people of other cultural backgrounds.

The BMI does not take into accountrepparttar ratio of body fat to muscle. Very fit, muscular people may register with a higher BMI but not need to lose weight.

A more reliable system to estimate how overweight you are and which takes into account your muscle mass isrepparttar 138346 amount of body fat as a percentage of total body weight.

Diet and Exercise Evolution: Adaptation (part I) -- Theory

Written by David McCormick

Training Weight training usesrepparttar principle of adaptation. By lifting a heavy weight, your body needs to expend some calories by burning blood-sugar and also uses up some nutrients. But that's trivial. More importantly,repparttar 138174 main effect of weight training is that inrepparttar 138175 days afterward,repparttar 138176 muscle will slightly increase in size and strength. Why does this happen? Adaptation. Becauserepparttar 138177 message you're giving your worker muscle cells is that their job is to lift a massive weight, and your survival may depend on it. Your muscle worker thinks: "I could just barely do that today, so tomorrow I'll need to be a bit bigger, just in case it happens again." The muscle is adapting torepparttar 138178 stimulus of a heavy load by making it a little easier for you to lift that load inrepparttar 138179 future.

Survive! To your body, everything is a matter of survival, andrepparttar 138180 most important element that your cells try to maintain is your energy. If you don't haverepparttar 138181 energy to chase down your food, you will starve, and if you don't haverepparttar 138182 energy to run away from a predator, you will be their food. If you burn though energy too quickly, there won't be enough left over to live on. That's why your body loves to keep fat: it's good for survival ifrepparttar 138183 food runs out.

The key to understanding adaptation is to think of yourself living inrepparttar 138184 African savanna, and what your activities would mean if they were applied only to your survival. When you run, your cells think, "We must be running to catch food, or to escape death!" That's all that cells know: survival.

Torepparttar 138185 bodybuilder,repparttar 138186 question becomes, "Will lifting a heavy weight make me stronger?" The answer is No! The immediate effect is that it will make you weaker. If you lift 100 lbs 10 times, does that mean that you can then lift 120 lbs right away? No, you're weaker and tired from your previous work. But your body will think that it needs to lift 100 lbs 10 times in order to survive, so it will adapt to make that a little easier for you next time. Taking a week off and allowing time for your muscle to grow a little bit will mean that you are stronger. So,repparttar 138187 next week you lift 120 lbs, and your body needs to adapt AGAIN, thinking that you now need to lift 120 lbs to survive. This makes you stronger week by week. "Will lifting a light weight 50 times make me stronger?" No! Your muscle will be exhausted, but you're asking for it to be able to last longer, not grow stronger. How will your body last longer? By adapting your energy stores (fat) to release more slowly and gradually. This is great for your endurance, but BAD NEWS if you want to look "ripped" with little body fat.

But adaptation does not only apply in this case. Your body adapts to everything. Everything you do and eat. So, you have to ask yourself, "Am I sending my cellsrepparttar 138188 right message inrepparttar 138189 things I do andrepparttar 138190 food I eat?"

Look forrepparttar 138191 sequel to this article, Adaptation II, for tons of examples and practical advice based onrepparttar 138192 principle of Adaptation.
