Dark beer is fuller bodied:
Colour has nothing to do with body, either. Guinness is measurably less full-bodied than some golden lagers. The fullness of body or otherwise, depends upon the density of grain with which the brewer started, and the degree of fermentation. The more the beer is fermented, the more the body diminishes. The body-building sugars are converted to alcohol. Unfortunately, alcohol is very calorific
