When we talk about how
much energy our bodies need throughout our day, we first need to understand
what energy is. We gain energy from our diets through the consumption of
carbohydrates, fats, proteins, and alcohol (in moderation). When these nutrients
are consumed, our bodies digest, absorb, metabolize and either use the energy
immediately or store it until it is needed for movement or exercise. A more
commonly known word for energy measurement within the body is Calorie (or kilocalorie).

Although Calories often
get a bad reputation for being the cause of weight gain, it is important to
remember that we need Calories to live and function. It is however more
important that we find ways to balance how many Calories that we consume a day
to that in which we need per day in order to control fluctuations in weight and
energy levels. As healthy active individuals we should think of Calories as our
energy needed for our daily living tasks and energy necessary for optimal
performance during exercise.

So you may be wondering,
“How many Calories do I need then?” This is a tough question to answer because
there are many different factors that influence energy balance for each
individual. Some common factors that affect energy balance are:

Some general
recommendations for Caloric intake have been made and consensus among
researchers show that the amounts needed can be categorized into four separate
groups of individuals and their requirements. Below is a table that shows the
different groups and the recommendations that have been given to each.

Example**
|
|
Sedentary Men and
Non-Pregnant Women |
Approximately 31
Calories / kg* of Body Weight |
60kg x 31= 1860 kcal
|
|
Male and Non-Pregnant
Female Recreational Athletes |
Approximately 33-38
Calories / kg* of Body Weight |
(Low End) 60kg x 33=
1980 kcal
(High End) 60kg x 38=
2280 kcal |
|
Endurance-Trained
Athletes |
Approximately 35-50+
Calories / kg* of Body Weight. Needs vary depending on specific sport and training regime. |
(Low End) 60kg x 35= 2100
(High End) 60kg x 50=
3000 kcal |
|
Strength-Trained
Athletes |
Approximately 30-60
Calories / kg* of Body Weight. Needs vary depending on specific sport and training regime. |
(Low End) 60kg x 30=
1800 kcal
(High End) 60kg x 60=
3600 kcal |
* To convert weight from pounds to kilograms, divide
weight by 2.2.
weight by 2.2.
**Example
132lbs / 2.2 = 60kg
132lbs / 2.2 = 60kg
Individuals who continually
consume too little Calories often do not consume enough nutrients which in turn
can cause a decrease in performance and overall energy levels. If low-Caloric,
low-nutrient diets put the individual at risk for muscle and bone mass loss,
inability to gain muscle or bone mass, fatigue, illness, menstrual changes, and
injury. For those who need to maintain a restricted Calorie diet should work
closely with a professional dietician to plan nutrient-rich, low Calorie diets
that will enhance their training performance while achieving training goals.
