The Harvard Health Letter notes that one of the problems with sweetened beverages is that they are watery. High-calorie drinks that are low-viscosity (thin) may deceive us by preventing our bodies from 'reading' calories, a capacity that depends, in part, on the thickness of a liquid.
In March 2006, the Beverage Guidance Panel issued a proposed 'guidance system for beverage consumption.' The six-level system emphasizes beverages with no or few calories—especially water—over those with more calories. It also recommends drinking no more than 8 fluid ounces of sweetened sodas, juice drinks, or energy/sports drinks per day.
