Psychology Glossary. Withdrawal. When an organism (does not have to be a human; can be another type of animal) becomes addicted to a substance, and then they are prevented from having that substance for an extended period of time, they go through a period of withdrawal. This period of withdrawal involves feelings of discomfort and distress. For example, a person addicted to cocaine may experience long periods of nausea, vomiting, cold sweats, headaches, mood swings, and other very uncomfortable feelings. Both physiological and psychological aspects are involved in withdrawal.
Fat has the most calories of all the nutrients: 9 calories per gram. In a healthy diet, about 30 percent of total daily calories should come from fat. This means eating about 50 to 80 grams of fat each day. Fat gives the body energy, too, but the body changes only about 10 percent of fat into glucose. By itself, fat doesn't have much impact on blood sugar.
How Many Grams of Fat Per Day. The number of grams of fat you can eat depends on the total number of calories allotted for your diet plan each day. Fat has 9 calories per gram. So someone who eats 2,000 calories per day is shooting for 20 to 35 percent of those calories from fat -- which is between 44 and 78 grams of fat per day.
