1. Describe WHY carbohydrates are the desired source of energy and sparing protein is important for life and homeostasis. How would you convey this to someone who wants to be healthy and go on a high protein, low carbohydrate diet?

2. Describe what happens when a friend goes on a crash diet to metabolism the first couple of days. Weight drops on the scale but what is that weight? If the diet continues after 3-4 days what happens to metabolism (what energy source is used) and how does the body respond with amount ant type ofweight loss?

3. Why would someone argue, using the information about metabolism and anabolism of fat, that fat is the most fattening for the body and that a low fat diet would be the best approach to lose weight? HINT: this is about metabolism and not just calories per gram.
