You'll know - 'metalic keto' taste in your mouth - lack of appetite - that different smell to your urin (oh the things we talk about here )

Raising carbs is not something to fret overly about - were you thinking of just 5 or 10g a day for OWL? Or are you thinking even higher for muscle growth? (you mentioned weight training in your initial post) - either one can be done with a LC plan - with results. If you are more active you a) need more carbs and b) will use those carbs.
