I'm on day 3 of Step2 CD. My keytone strip looks like I'm moderate or there abouts (4.0). I've read on here that it is better to be purple which suggests large/high levels of keytones (16). I then read the leaflet and an article online that said you are better to be between trace and moderate for optimal fat loss. Is this true? Just worried if it is dangerous to be on the deep purple higher end.
