Over 5 Consecutive days, I completed a journal of my diet and recorded the total amount of kilojoules I consumed each day. The results were as follows:

Day 1 - 8457.5kj

Day 2 - 6722.5kj

Day 3 - 5330kj

Day 4 - 6642.5kj

Day 5 - 7407.5kj

In establishing my total energy needs I had to consider my involuntary energy demands such as age, body weight, gender, and my metabolic rate and I had to determine the amount of energy I required to undertake voluntary physical activities throughout the day. The amount of energy I required for a particular activity depended on, the intensity of the activity; the time spent doing the activity and the type of activity.

I did this by matching the description of each activity level that the class agreed on, with my daily activity level then multiplied this figure with my BMR to come up with my energy expenditure for the day.

The results were as follows:

Day 1 - 8311.68

Day 2 - 7849.92

Day 3 - 7849.92

Day 4 - 7849.92

Day 5 - 7849.92

According to the Australian Guide to Healthy Eating, 12-18 year old adolescents require between 7200 and 13500 kilojoules each day. When comparing my results with this I found 3 out of 5 days I consumed lower than the recommended amount of kilojoules for the day. In terms of energy balance, 4 out of 5 days, my energy intake was only a minimum of 400 and a maximum of 2000, under my energy output and 1 out of 5 days, my intake was slightly higher than my output which gives me a reasonable balance between energy expenditure and energy intake, therefore neither weight gain or weight loss will occur.

As a growing adolescent I think these...
