Document Summary
A person"s energy balance depends on two factors: Dietary intake of calories from carbohydrates, fats, and proteins. Dietary expenditure in maintaining the bmr and for various other activities including physical activity. Calories in - calories out = calories gained/lost. Calories gained are primarily stored as fat. Directly converted into body fat; easiest and most effective process to convert excess dietary fat into body fat. Broken down into glucose and absorbed into the body. One absorbed, glucose is utilized in its pure form by blood cells, nerve and brain cells. Excess glucose converted to glycogen; glycogen storage areas are limited and once full, excess carbohydrate usually displaces fat from the fuel mix. Fat formation from glucose usually only occurs when excessive amounts of carbs are consumed. Broken down into amino acids and absorbed; protein"s primary role is repairing tissue. Excess amino acids cannot be stored and have to be converted into other compounds.
