The Importance Of Combining Nutrition And Workout For Weight Management

By Andy G Smith


A person's daily calorie expenditure is dependent on 3 main factors. Firstly, it will depend on an individual's basal rate of metabolism (BMR), which represents the amount of calories burned at rest because of metabolic functions inside the body. This can be estimated as 25 calories per kg of body mass, daily.

The second factor to be considered is a person's life-style and basic activity levels (Activity Factor, F). People who are usually more active during the day will consume more calories than an inactive person. Below is an approximation of the additional calories used because of life style activity. This is just an estimation as it's difficult to clearly define levels of activity in this manner:

Usana Macro Optimizers - The Right Macronutrients: It's crucial that your diet include the right types of each class of macronutrient. The proper carbs are generally complex carbs or fiber, and have a low glycemic index. Complex carbohydrates and fiber usually supply extra healthy trace elements and phytonutrients, and energy. A healthy diet should also include a number of protein sources like complete proteins, which contain all the essential amino acids.

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

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

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

To approximate your weekly calorie expenditure, you can enter your own details into the equations below: Firstly, calculate you BMR = Weight (kg) x 25 =; Next, include calories relating to your activity level = BMR x F = (Sedentary Life-style = BMR x 1.2, Moderately Active Life-style = BMR x 1.5, Really Active Life-style = BMR x 1.75); Now multiply by 7 for days of the week = BMR x Activity Factor x 7 = ; Finally, add calories expended during formal exercise during the week = BMR x Activity Factor x 7 + Calories Expended During Exercise =; This provides you the total amount of calories used up in a particular week.

In order to balance your calories for a given week, just subtract the number of calories expelled from the number of calories taken in: Weekly Calorie Consumption - 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 estimation, to reduce your body mass by 1kg, you need to expend 7000 calories more than you intake. On the other hand, to gain 1kg, you need to intake 7000 calories more than you expend.
