this question has been nagging me for awhile...do you think burning dietary fat could turn ketostrips purple? I mean, with the high amounts of fat we eat how do we know it is burning STORED fat that causes the high levels of ketones in urine, and not just the mayo, cream, butter, pork rinds, etc we ate that day????? several people on this board have commented that the more fat they eat, the darker their strips are!!!! Coincidence?????

It's not a coincidence. ANY fat burning will turn the strips.
Remember, they aren't to gauge how well you are doing, just
if you have reached ketosis. Don't be a slave to them, they are just a tool to use along the way. It doesn't matter if the fat is coming from dinner or from your gut, you are in fat burning mode which is the important part.

If you eat a meal of high fat and measure shortly thereafter the probability that some or most of those ketones are dietary fat. I find that my most accurate readings come in the first morning urine. If I show at least pink then I know I'm burning fat. If I measure say 4pm after a high-fat lunch, then its purple and I know that its partially due to the consumption.

so wouldn't it stand to reason that the more fat we burn from our diets, the less fat we are burning from our gut? I know we are supposed to eat fat liberally on this plan, but can eating too much keep us from burning stored fat?

Yes, that is why this isn't an "All you can eat" plan. Eat till you are satisfied, not to excess. There is no way to differentiate where the fat you are burning is coming from. What you seem to be leading to is trying to do a low-fat low-carb plan... which is a bad idea.

If you cut the fat, where will your calories come from? If your calorie intake drops too low your body goes into starvation mode, and you will lose nothing.

The recommendation is that 70% of your daily calories comes form fat.

the funny thing is that I know all of this...I've read and re-read the Atkins books a zillion times. I guess I can't help second guessing myself! I don't know what I'm complaining about anyway, I know this wol works....I've lost almost 30 pounds effortlessly! thanks for the replies, though!

Actually, here's a quote directly from the Atkins Center--
