To explain why,when we have unlimited access to various tasty foods,we tend to overeat and gain weight,some researchers use the term ________ to indicate a person's base weight level.

A) homeostasis
B) basal metabolic rate
C) metabolism
D) settling point

The term "settling point" refers to a person's base weight level, which is determined by a variety of factors including genetics, environment, and behavior. When individuals have unlimited access to tasty foods, they tend to overeat and their weight may increase beyond their settling point. This can lead to weight gain and other health problems if not addressed. Homeostasis refers to the body's ability to maintain a stable internal environment, while basal metabolic rate and metabolism refer to the amount of energy the body needs to carry out various functions. These terms are not directly related to the concept of settling point and overeating.
