People misunderstand General Relativity too... doesn't make it a fad. A fad is a short-lived craze. Generally it's something that's done for fashion/popularity sake, but has little underlying benefit or scientific basis. Atkins published in the 1970's. Low carb diets have been popular for almost a decade now - and the evidence for their efficacy appears to be mounting. It's no longer a fad. Regarding your points: 1) I've never heard that claim and I've been on some form or other of a low carb diet for the last ten years. 2) Magical? Hardly. The first time I forced my body into ketosis was the most difficult, though. When my metabolism switched to burning fat, I woke up that day feeling very different. That difference was a bit euphoric. 3) Being in ketosis isn't like being pregnant. There are varying degrees - hence the spectrum of colors on the ketostix. That said, there is a slippery slope where indulging "delicious things" can quickly lead to carb cravings that wreck your low carb eating regimen. Some people are better off just avoiding the treats because it makes sticking with their eating plan easier.
