A calorie is a measurement of energy that comes from food. You obtain calories from the food you eat. There are 4 calories per grams of a carbohydrate. You can get 9 calories from 1 gram of fat and 4 calories from 1 gram of protein. Therefore, this is a way to measure the amount of energy expenditure and how food is broken down and utilized by the body.
Breakfast is the most important meal of the day.
We should say, it is important in children and adults. At night, if we overeat, our bodies tend to store or hold on to that because our metabolism has become depressed. We need to retrain our thinking to eat a larger breakfast and lunch, and less in the evening. I like to jog 4-5 miles a day. Hopefully you are eating continuously throughout the day.
