Ok, Lipids? Cool They're important because???
Lipids are an important factor in animals. Lipids store energy. Lipids have structures that allow food to digest. Fat needs to be stored. The energy that is used is provided to hormones. Fat has insulation so you are kept warm. Like seals have blubber. Fat in food adds insulation but it also adds weight to animals. It's imperative that lipids should be watched carefully in diets as it should be consumed in moderation. Too much lipids can cause obesity which currently affects 26.5% of Americans. Now enjoy your lipids (just a dab) and they are cool. Work out so you can eat more lipids. (The unsaturated ones of course.) So you wont get into an accident. i.e. He needs some milk.
