Pre-Lab Questions:

”1. How do the intake of nutrients and expenditure of energy relate to a metabolic level?”

 Different nutrients have different calorific content. During exercise, your body requires more

 energy so it is ideal to consume food with high calorific content such as carbohydrates and

 fats. In the more intense activities, your body’s metabolism increases thus requires more

 calories for energy.

”2. Do you think you take in more calories than you burn in a day? Why or why not? ”

 Yes, I do because I’m a stress eater and I can’t always find the time to exercise.

Experiment 1: Tracking Your Nutrition

”Analysis: According to the chart, I ate consumed more calories than needed everyday. I am not

surprise by this result though because I know that I am a snacker and I tend to drink a lot of

sugarly drink throughout the day. To improve my nutrition, I would eliminate sugarly drinks

from my diet and drink more water. I would also exercise into my daily routine.
