1. What is a calorie? A calorie is a unit of energy. It is recommended that we consume a regular amount of calories on a daily basis for us to function. Different kinds of foods contain different numbers of calories. Here are the basics: one gram of carbohydrates contains four calories, one gram of protein also has four and one gram of fat equals nine calories.
2. Can a person just have one source of calories? Yes, a person can but they shouldn’t. A balanced diet is always suggested. Ideally, about 50 percent of the calorie intake should come from carbs, 20 percent from protein and 30 percent from fat. However, fat is tricky. We should consume fat from monounsaturated sources. Otherwise is unhealthy.
3. What happens to calories? When we eat, food is broken down by the digestive system and is either used up through cellular and physical activities. When we walk, breathe or just move any part of our body, a small amount is being burned. The unused energy is stored as body fat. Roughly 3,500 stored calories equates to a pound of body fat.
