I don't think so. Its been going on for 30 years and is getting stronger. Even doctors are starting to recommend it. That's not a craze. Back when I first did CAD in the early 90's low carb was REALLY underground. I did run a low carb e-mailing list back then with a recipe archive ftp site. There were NO low carb products back then and sweeteners were pretty lame. I think aspartame was about it.

I think the low carb products are going to work nicely into maintenance. To a lesser extent during my weight loss phase.
