A simple apparatus for comparative measurements of energy expenditure in human subjects: the thermic effect of caffeine.
A simple inexpensive indirect calorimeter that is suitable for the estimation of energy expenditure in man is described. Its usefulness is demonstrated by a study of the effect of coffee on energy expenditure. Caffeinated coffee increased energy expenditure by 16% over 1 2-h period compared with decaffeinated coffee.
