Calories from all the food and drink you swallow adds up. Some foods provide more calories than others. Foods that are high in fat, generally are higher in calories. Choosing low-fat foods can aid in weight loss by reducing total calorie intake. Don't cut out all fat items.
Many athletes feel that fat intake is the culprit to unwanted weight gain.
Although excess fat intake leads to weight gain, a certain amount of fat is necessary to maintain good health and performance. Eat bigger meals earlier in the day, when activity is greatest, and smaller meals in the evening. Eat meals and snacks throughout the day to maintain blood glucose and energy levels. During the evening, activity is usually minimal. As a result, a large meal will more likely be stored as fat.
