Textbook Question
Chapter 23, Problem 13RQ
Hunger, appetite, obesity, and physical activity are interrelated. Thus, (a) hunger sensations arise primarily from the stimulation of receptors in the stomach and intestinal tract in response to the absence of food in these organs; (b) obesity, in most cases, is a result of the abnormally high enzymatic activity of the fat-synthesizing enzymes in adipose tissue; (c) in all cases of obesity, the energy content of the ingested food has exceeded the energy expenditure of the body; (d) in a normal individual, increasing blood glucose concentration increases hunger sensations.

What happens physiologically during starvation?
The body doesn’t have a reserve of proteins or amino acids for energy production. Which class of protein may be used initially during fasting to maintain glucose and energy levels? What is the difference between a glucogenic and ketogenic amino acid and why are both important during fasting?
