"If you're excreting ketones in your urine, then the LTS will turn purple. The more ketones excreted, the darker the purple."

"To see them go from beige to purple is to receive in chemical code the message I'm losing weight."

"We're going to make sure those LTS turn purple."

All I'm saying is that Atkins makes it sound like the more ketones (or the "purpler" the stick), the better. If this isn't true, I can accept that -- I would just like some proof. I mean, hey, if I can lose as much weight in pink as I would in dark purple, then why strive for the purple? I just want to know.

Sorry it took me so long to respond, but my mom had my copy of the book -- she's planning to start the diet Monday!
