Basics of Weight Management


First off, there are six classes of nutrients: carbohydrates, fat, protein, vitamins, minerals, and water. The energy-yielding nutrients are carbohydrates, fats, and protein. These nutrients provide the body with energy, such as doing work, moving or heating something. Most importantly, a Calorie, is the unit used to measure energy.

Carbohydrates, proteins, and fats yield out different amounts of calories.

Carbohydrates - 4 calories/gram
Protein - 4 calories/gram
Fat - 9 calories/gram

Alcohol - 7 calories/gram (nonessential nutrient)

Vitamins and Minerals
