Calories and Diet

This content was STOLEN from BrainMass.com - View the original, and get the already-completed solution here!

Please explain the relationship between calories, food, and heat by responding to the following prompts:

1. List the 'magic formula' for weight loss. List a high-calorie food and a low calorie food. Do you see a relationship between the high calorie foods and the low calorie foods (other than the number of calories?)

I can only think that less calories in and more calories burned, but am not able to take it a step beyond that in Chemistry terms.

2. Explain why food has caloric values listed on the package. Relate food 'calories' to heat 'calories'.

3. Water is often used as a heat sink because of its high specific heat. Explain what this means and give examples where this is used.

4. There is a diet called the master cleanse diet where you only drink water with cayenne pepper and maple syrup in it for anywhere from 14-30 days. Why the cayenne and maple syrup (from a chemistry perspective) and isn't this considered starvation?

You're correct about taking in fewer calories than you burn for weight loss. Essentially, calories are a measure of energy, so in chemistry terms, you need to use more energy than you take in. A high calorie food would be cake ...
