Generally, fats are needed by your body. Fat isÂ required for the formation of vital parts of your cells and for cushioning the vital organs as well. Â There are two kinds of fatâ€”good (HDL) and bad (LDL). HDL means high density lipoproteins. These are what you should always take in so that your cholesterol level may be lowered and so that you may be able to have good circulation and a good storage of energy. LDL or low density lipoproteins are the bad fats that you should keep away from because these are the culprits when it comes to very poor health. Not only will you have undesirable curves, but also diseases of the heart, blood vessels, and liver, among others.
