Actually I know several companies have low carb products in the pipe line so I don't think that low carb is going away any time soon.
What will go away are the low carb that aren't. Yopleit yogurt, these drinks, some of the breads and all the stuff that is loaded with sugar alcohols.
I really hope that at some point they learn to make a decent sugar free ice cream.
I'm not convinced there will be a good sugar free ice cream unless someone does something with splenda. Good point about the 'low carb' products that aren't. Candy bars???
