Determining Your Weekly Calorie Expenditure And Needs

By Andy G Smith


A person's daily calorie expenditure is dependent on three main factors. First of all, it'll depend on a person's basal rate of metabolism (BMR), which represents the amount of calories burned at rest because of metabolic functions inside the body. This could be estimated as 25 calories per kilogram of body mass, daily.

The 2nd factor to be considered is an individual's life-style and normal activity levels (Activity Factor, F). Those who are normally more active during the day will use up more calories than an inactive person. Below is an approximation of the extra calories used because of life-style activity. This is just an approximation as it is hard to clearly define degrees of activity in this manner:

The answer to this is YES! The type of training you do may enhance your body's ability to burn fat. The human body can only burn fat when both carbs and oxygen are present and so if you are aiming to reduce weight, you have to encourage your body to store carbs (in the muscles) and use oxygen more efficiently. This is an excellent argument for why low carbohydrate diets aren't ideal, because if there are no carbs present in your body, then lean body mass is broken down to replace them.

Somewhat Active Life style (=BMR x 150%) - Usual characteristics include having a job requiring prolonged times of standing (factory worker or nurse), cycling or walking to work, taking staircases not elevators, etc.

Usana Macro-Optimizers - Why Low Fat And high Fibre? Soluble fiber, in a diet low in saturated fat and cholesterol, may decrease the risk of heart problems. Low-fat diets full of fiber containing grain products, fruits, and veggies might also decrease the risk of many types of cancer, a disease associated with many factors. It's believed that the regular diet in the current society includes only one half to two-thirds of the fiber essential for optimal health. The positive effect of a high fiber diet is increased when there's a concurrent decrease in the quantity of saturated fats taken.

For weight gain, the objective of exercise is to make sure that the mass gained is lean tissue mass and not fat mass, therefore how is this reflected in the type of physical exercises performed?

To approximate your weekly calorie expenditure, you can enter your own information into the equations below: First of all, calculate you BMR = Weight (kg) x 25 =; Next, include calories associated with your activity level = BMR x F = (Sedentary Life style = BMR x 1.2, Somewhat Active Life-style = BMR x 1.5, Extremely Active Life style = BMR x 1.75); Now multiply by 7 for days of the week = BMR x Activity Factor x 7 = ; Lastly, add calories used up during formal exercise throughout the week = BMR x Activity Factor x 7 + Calories Used up During Exercise =; This provides you the total amount of calories expended in a given week.

To balance your calories for a given week, just subtract the number of calories expelled from the amount of calories taken in: Weekly Calorie Intake - Calorie Expenditure = Net Weekly Calories; If this result is negative, your weight is likely to decrease and if it is positive, your weight is likely to raise. As an estimation, in order to decrease your body mass by 1 kg, you need to expend 7000 calories more than you intake. Conversely, to gain 1 kg, you have to intake 7000 calories more than you expend.

In conclusion, the type of training we do may encourage adaptations within our active body tissue. These adaptations permit our body to work in a way that is in keeping with our goals. Although our diet might determine whether we drop or gain weight, our choice of training methods will define the way our body generates and manages energy at rest, along with during exercise. Even if somebody were to train for 5 hours per week, there would still be 163 hours in the week when they weren't training. Hence it makes more sense to encourage your body to adapt in a manner that it will function in keeping with your goals during rest, rather than purely concentrating on the direct effect of your training.
