Body Fat Formula
I see guys posting here about losing weight instead of losing fat. Here is a really simple and useful formula.

Men's %Fat = (-98.42 + 4.15*waist - .082*weight)/weight,

Women's %Fat = (-76.76 + 4.15*waist - .082*weight)/weight.

For our "model woman" who weighs 132 pounds with a 29" waist,

%Fat = (-76.76 + 120.35 - 10.824)/132 = 24.823.

There are more complicated formulas, and I have seen inaccurate results with skinfold calipers and electrical impedance measurements. This formula is great because it tells you to get big with a small waist. You will need to get strong, with big legs, ass, back, chest, and shoulders.

It helpful new diet persons. I'm doing many search on net about body fat calculation. But have no found any satisfactory web site.

Far way from it! Many start a diet, together with sports & cardio. This will, if not done correctly burn your muscles & keep your fat. Muscles are heavier then fat, so they'll loose lots of kg, but also muscles.

Muscles burn lots of kcal, if you loose muscles, you'll need to keep a harder diet regime every time and/or do more cardio (which will also burn more muscles). It's a virtual circle.

There are some good calculations on the net including your current % of body fat, age, size, minutes cardio/week, minutes powertraining/week, time of work/week,... to determine the +/- right volume of kcal you need.

To loose fat, you deduct around 500kcal per day of your calculated figure. You need enough food in your body to build it. The more your sport, the more you'll be eating.

To much cardio is bad to by the way. Limit it to 3, max 4 times a week with sessions of max 45 minutes.
