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.
While fat is an important part of a healthy diet, it's as important not to get too much as it is not to get too little. Eating too much fat can lead to weight gain and health problems, including high cholesterol.aturated fats and trans fats should be limited in a healthy diet. Unsaturated fats, on the other hand, found in fish, nuts, olive oil, canola oil and vegetable oil, are considered good fats.. Your fat intake should make up no more than 35 percent of your daily calories.
