Energy is expressed in Kilocalories (Kcal) or Kilojoules (kj).
The amount of energy you need per day depends on your Resting Metabolic Rate (RMR) PLUS the amount of energy you use during physical activity and is often called your Total Daily Energy Expenditure or Requirement (TDEE).
The RDI’s for energy shown here are population-based average estimates ONLY and don’t reflect large individual differences due to extra exercise or intense physical work or no physical activity at all, i.e. bedridden.
Our free RMR and TDEE calculator enables you to calculate your TDEE much more accurately.
Upcoming posts will show foods that are of particular interest because of their calorie content. Included will be commonly eaten processed foods so you can see what you’re putting away if you indulge. These processed foods camouflage calories and we often pay the price.
Energy intake is crucial for life.
All metabolic processes in the body utilise energy in one way or another. The primary sources of energy from the diet are Carbohydrates, Fats, Protein, and Alcohol.
Even if you’re trying to lose weight, energy intake is essential.
Otherwise, you will also lose precious muscle mass. The more work you do, the more energy you need from food. However, sitting still ALL day still uses about 1433 Kcal for women or 1552 Kcal for a man.
