1. A friend is concerned because her doctor told her she would be more likely to lose weight by eating regularly and not skipping meals. However, when she eats breakfast, she is always hungry long before lunchtime. When she skips breakfast, sometimes she is not even hungry for lunch. You have just learned that skipping a meal slows the body’s metabolic rate. If metabolic rate is slowed, weight loss is slowed. Therefore, you tell her that she is more likely to lose weight by eating four to six small healthy meals a day instead of eating only one large meal. In other words each time your friend skips a meal (stimulus), the metabolic rate slows down ( response), and the individual is less hungry (stimulus is magnified).
