Answer to Question 1

Positive energy balance occurs when energy intake > energy expenditure. Negative energy balance occurs when energy intake < energy expenditure. In most cases, weight change is a good indicator of energy balance: Weight gain indicates positive energy balance, weight loss indicates negative energy balance, and no change indicates energy balance.
Positive energy balance is desirable during periods of growth such as infancy, pregnancy, and intense weight training to increase muscle mass. Negative energy balance is the goal for individuals who want to lose weight.

Answer to Question 2

Acetaldehyde dehydrogenase or ALDH
