I saw that too. My anecdata: In 1992 I was 5'10" and 210lbs. I switched from caloried drinks to non-caloried drinks (coke -> diet coke) and have up sides (no more fries). No other changes. Lost 30 lbs and pretty much stayed that way. Pretty much no real physical activity. Don't know which it was, the drinks or the sides or both. Stayed that way until I moved to Japan in 1998 where most restaurants don't have diet coke. They're only non-caloried drink was tea which got me addicted to tea. That's probably better for me than diet-coke but tea stains my teeth :(
