You may notice on the nutritional labels of the foods you buy that the percent daily values are based on a 2,000 calorie diet -- 2,000 calories is a rough average of what people eat in a day. But your body might need more or less than 2,000. Height, weight, gender, age and activity level all affect your caloric needs.
Estimated calorie needs range from 1,800 to 3,000 per day, according to the U.S. Department of Health and Human Services. If you need 2,200 calories per day and you eat two snacks, subtract 100 calories for each, and that leaves you with 2,000 calories.
