Problem 7: Metabolic Activity and Weight Loss

Studies on forced weight gain and weight loss that measured metabolic activities showed why lowering caloric intake rarely results in sustained weight loss. The basic observation was that metabolic activity:

	increased with forced weight loss and decreased with forced weight gain in obese and normal individuals.
	decreased with forced weight loss and increased with forced weight gain in obese and normal individuals.
	increased with both forced weight loss and forced weight gain in obese and normal individuals.
	decreased in obese individuals with forced weight gain and increased in normal individuals.
