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.
The latest Dietary Guidelines for Americans recommends keeping saturated fat to less than 10 percent of calories a day. For a 2,000-calorie-a-day diet, that's 200 calories or about 22 grams of saturated fat. Use the Nutrition Facts label to find out how much fat is in the foods you eat.
