Multiply the number of grams by 4. This gives you the number of calories of carbohydrate you have eaten. You already know that too much fat contributes to many of today's common causes of death, such as heart disease and cancer. Fats carry compounds that give foods their enticing flavors and aromas, and because fat leaves the stomach slowly, it leads to greater satiety. Fats are often referred to in terms of saturated and unsaturated.
Saturated fats are solid at room temperature.
These fats pack together tightly and squeeze into small spaces, such as arteries, causing dangerous blockages. Unsaturated fat does not pack as easily - the charge of the atoms around unsaturated fat molecules causes them to repel each other, making them less of a clogging threat to arteries than saturated fat. If you eat more than you need, the extra food is stored as fat. Eating excess fat can indeed make you fatter than eating excess carbohydrate and protein. The body expends energy in converting carbohydrates and proteins to stored fat, but it uses less energy when converting fat to stored fat.
