The caloric intake for an individual is the daily calories needed to maintain weight and provide the body with enough fuel for energy. Calories are consumed in the diet. Each protein, carbohydrate and fat source provides calories. These calories are used in the cells for energy, so the body can function. When you eat less than required, your body turns to its fat stores, where it finds more fuel. Knowing the caloric intake for the body helps you determine how to eat to maintain weight and health.
Significance
The main energy currency of the cell is adenosine triphophate (ATP). The energy contained in ATP is what fuels the body's ability to undergo reactions. These reactions control every part of the body, like vision, muscle control, immune responses and repair of damaged tissue. The caloric requirements promote health, so it's important not to starve when dieting to lose weight.
Identification
Online calculators provided by reputable sources help you determine how many calories you burns in a day. Use the Baylor College of Medicine calculator to determine the calories burned each day (see Resources). The factors involved with the calculation include your sex, weight, age and daily activity. Men burn more calories than women, and people who are sedentary have a lower caloric consumption requirement.
Types
The three sources for calories are proteins, carbohydrates and fats. According to Penn State University, proteins contain 4 calories for every gram. Carbohydrates also provide 4 calories per gram. Fats have the highest number of calories in each gram--9 calories. This is why fats are stored in fat deposits around the organs and under the skin. Fats are also used as a cushion for the organs.
Time Frame
People who want lose weight by watching their caloric intake requirement should cut calories in the daily diet. Exercise also helps you lose weight more quickly. By cutting 500 calories a day from the daily caloric intake, you can expect to lose about 1 lb. a week. According to Fort State Valley University, there are 3,500 calories in 1 lb. of body weight. This means that for every 3,500 calories reduced each week, you can lose one pound of weight, since the body will use the stores for energy.
Considerations
The caloric intake requirement can be used to maintain body weight as well. When choosing foods, ensure you are eating a balanced diet with fewer fats. Foods like vegetables, lean proteins like chicken and turkey, and fresh fruits provide calories. Saturated, fatty foods have been linked to heart disease, and too much fried foods or red meat can raise cholesterol levels.
