b. More and larger fat cells are found in obese people compared with healthy-weight persons.
c. Fat cell number increases most readily during early adulthood, when energy expenditure declines.
d. Fat cells may enlarge but not increase in number upon reaching the age of 50 in males and reaching menopause in women.
e. When energy out exceeds energy in, fat cell size and number both decrease.
