Mr. X.................
I just did a search and found this from one of your earlier posts, could this be my problem? or am I just doomed to drink water only
Well, here is the problem, and original Dr. Atkins pointed out that Diet Coke was going to "kick" you out of Ketosis, yet he provided no scientific data to back up his statement.
Over the years, (after extensive chats with Lyle McD) I have come to the conclusion (science at hand) that diet coke gives you a FALSE negative reading on the Ketostix and doesn't kick you out of Ketosis. Now, how does this relate you might ask?...
Well, the problem you are facing is that the Caffeine is the culprit that's giving you a false reading not the other products. If you have been doing everything to the DOT, then DO NOT worry about the occasional negative readings.
A good way to test this theory is to stop taking ECA for 2 days and test your ketonic levels 6 times a day, and to see how fast ketone readings come back. Again, as I've said in the past, a KETONE meter is highly recommended, the $100 is well worth it.
