People who eat fat are fat. Well, no, not necessarily. Let us explain: Our bodies need dietary fat (which is why many fats are called “essential”) in order to lose weight and function properly..
You may wonder isn’t fat bad for you, but your body needs some fat from food. It’s a major source of energy. The right kinds of fats help increase satiety, maximize your metabolism, protect against heart disease, speed nutrients through your body, and improve your fat-soluble vitamin uptake
Fat is needed to build cell membranes, the vital exterior of each cell, and the sheaths surrounding nerves. It is essential for blood clotting, muscle movement, and inflammation. For long-term health, some fats are better than others.
Good fats include monounsaturated and polyunsaturated fats. Bad ones include industrial-made trans fats. Saturated fats fall somewhere in the middle.
When you dip your bread in olive oil at an Italian restaurant, you’re getting mostly monounsaturated fat. Good sources of monounsaturated fats are olive oil, peanut oil, canola oil, avocados, and most nuts, as well as high-oleic safflower and sunflower oils.
When you pour liquid cooking oil into a pan, there’s a good chance you’re using polyunsaturated fat. Corn oil, sunflower oil, and safflower oil are common examples. Polyunsaturated fats are essential fats. That means they’re required for normal body functions but your body can’t make them. So you must get them from food.
It is generally believed that high fat diets may lead to the development of obesity and several other diseases such as coronary artery disease, diabetes and cancer. In contrast, our laboratory has recently shown that a ketogenic diet modified the risk factors for heart disease in obese patients (NCBI)
