A recent study out of Texas blames sugar-free soda for people getting fat, saying they drank a diet coke but gave themselves free rein on high-calorie foods.
UW Medical School Associate Dean Pat Remington is skeptical about the results, arguing there's little evidence to support that theory applying to everyone. He says drinking water is still the best option, but diet sodas have no calories.
Remington says the real problem is those who drink large amounts of regular soda and sports drinks containing lots of sugar. He says those drinks can each contain 300 calories or more and are more likely to cause people to pack on the pounds.
