i am about 5'8'' and 125 lbs. and "dark hand" i'm sorry but the 1% body fat would be completely unhealthy. you'll either be a dead stick, or an arnold schwartzenegger body builder. those are the only ways to have such a low body fat. you're probably like 6-7% at the lowest.
but i've heard of some stuff to do. mainly, like everyone else says, stay off the simple sugars. (if you want, look up some organic chemistry stuff on the internet or a book, and you'll begin to understand how fat molecules and stuff like that work.) basically, fatty acids are a good thing. that's why the atkins diet is so popular. fat from animals (meat) is a good thing, of course, not in excessive amounts. stay away from trans-fats as well as the simple sugars. in the good fatty acid molecules, the chemical bonds between the carbons and hydrogens are "cis" on the same side of the carbon carbon double bond. these things are liquid at room temperature (oils) . olive oil, safflower oil, and that sort are most healthy.
\ = / (i hope you will understand my pics.)basically, these cis bonds, cause kinks in the fatty acid tail and don't allow them to stack on top of eachother. that's why they're liquid at room temp.
on things called trans-fats, the "cis" bonds are switched to "trans" bonds.
\ =
\ (kinda like that)
anyways, these bonds are on man-made fatty acids. things like margarine and that bad shit are to be greatly avoided.
on the fat molecule like butter, there are no double bonds. they have an amino acid head and the fatty acid tail are those squiggly looking pictures in chemistry class. /\/\/\/\/\/\/\/\/\/\/\/ all those are, is carbon carbon bonds, and on each bond, there are hydrogens.
sorry if i confused the hell outta you guys. in my college chem class, i was pretty confused too.
