Anything that comes in excess may not be favorable for you. As a generic prescription in a fit lifestyle, everything should be taken moderately. However, there are some cases that it is grueling to abide by the rule. Fat for example, if taken overly is not good to our health. It can lead to obesity, heart problems, diabetes and cancer. However, it should not be entirely expelled in the diet. It is also indispensable in order for the body to break down some vitamins like Vitamin A, D, E and K, deposit energy to fuel the metabolic process, and insulate body organs. So to make sure we prevent fat-related conditions, we should lessen our fat ingestion but never get rid of it completely.
