Bump, I am interested as well!

Mine is typically between trace and moderate. As long as its not negative, you should be fine. Ketosis is ketosis

I am relatively new to Keto and I finally got my Ketostick to turn a different color this morning. Very happy to be in Ketosis. Now my question is what color is optimal for the best fat loss where I'm still being healthy about it?? I wonder if it's different for everyone?

I think it depends. Mine goes between moderate and high. If you're dehydrated it can show a dark purple too, so light sticks aren't necessarily indicative of being out of ketosis if you have all the other symptoms of ketosis. Also, someone correct me if I'm wrong, but as you get more keto-adapted, you don't necessarily show dark pink or purple on the sticks as much as the earlier days when your body is throwing out more ketones.

I'd stop worrying about ketosis and what color your sticks are. Personally I wouldn't waste your money on ketostix. Eat your macros, log your food accurately, and you should see progress. There's no "optimal state of ketosis for fat loss" - fat loss is going to be determined by your caloric deficit.

Here's what I've gathered after reading a ton of articles and posts.

Ketostix can be relied on to show if ketone bodies are present. Apparently, there is no such thing as "low level" or "high" ketosis. It's an either or thing. That said, ketostix cannot give a false positive. They can however give a false negative, for a number of reasons, such as:

-You are in ketosis, but do not have ketones in your urine
-You are in a higher state of hydration (delutes the urinary ketones)
-Hormonal changes
-Normal daily fluctuations

Bottom line is that while the readouts can be psychologically reassuring, they aren't the end all, be all. As long as you use them only as a general indicator, knowing the margin for error, I think it's a nice tool to have in the back drawer

I know I posted last month but I want to chime in.

The other thing with ketostix is that you'll find you really don't need them after a certain point. When I first started keto, I was obsessive about measuring if I was in ketosis or not. Then gradually I figured out yeah I am because I'm hitting my macros everyday. At this point, the only time I use ketostix are if I have a day where I think I might have goofed up my carbs (going out to eat) just to check, but otherwise they are entirely unnecessary. Keto is keto.
