Determining Your Per Week Calorie Expenditure And Needs

By Andy G Smith


Virtually all serious degenerative diseases that plague today's world are believed to be caused or exacerbated by the deterioration of the current diet. USANA Foods were developed to offer the great tasting, high-quality macronutrients which your body needs to maintain health and feel happy. These hassle-free, low glycemic foods may be used with the Usana Essentials and Usana Optimizers to complete your proper diet. Many USANA Foods contain useful elements like dietary fiber, soya protein, and potassium.

The second factor to be considered is an individual's life style and basic activity levels (Activity Factor, F). Those who are generally more active during the day will consume more calories than an inactive person. Below is an approximation of the extra calories used due to life style activity. This is only an approximation as it's difficult to clearly define degrees of activity in this way:

Sedentary Life-style (=BMR x 120 %) - Normal characteristics include having a desk based job (office worker), driving to work, taking the elevator and not the stairs, and many others.

In order to promote the adaptations discussed, your cardiovascular exercise must be done at a comparatively high intensity (a minimum of 70% of your maximum heart rate - providing you have a realistic cardiovascular fitness base to begin with!). This will promote an increase in the number of mitochondria within the muscles, permitting higher uptake and utilisation of oxygen.

For weight reduction, resistance exercises should be done with repetition ranges of 15 and above, as this will improve the endurance capacity of the muscle. The muscle will once again produce higher numbers of mitochondria in order to decrease lactic acid production, therefore increasing the muscles ability to use oxygen.

For weight gain, the purpose 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 kind of exercises performed?

High glycemic foods offer quick energy, but it's normally short lived and hunger soon returns. Low glycemic foods offer greater satiety and sustained energy, that makes eating less and weight loss easier. High-glycemic diets also have been associated with weight problems, type II diabetes, insulin resistance, and heart disease. Almost all convenience foods and lots of meal replacement and diet products available today are unfortunately, high glycemic.

To balance your calories for a particular 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 will probably reduce and if it's positive, your weight will probably raise. As an approximation, in order to reduce your body mass by 1kg, you have to expend 7000 calories more than you intake. Conversely, to gain 1 kg, you have to intake 7000 calories more than you spend.

A person with weight reduction goals should aim to lose between 0.5-1 kg bodyweight per week. Aiming to lose more could result in a slowing of the rate of metabolism, as the body goes into a state of starvation. Therefore, a weekly calorie deficit between 3500 and 7000 kg is required (net calories = -3500 to -7000). A person with weight gain goals, aiming to gain between 0.5 and 1 kg body weight per week will need a weekly calorie surplus between 3500-7000 (net calories = 3500 to 7000).
