Keep track of what you eat to narrow down or rule out food allergies or just keep track of your keto diet! The journal is set out for daily tracking of every meal, snacks and supplements/meds with an end of week summary of what worked for you or what your suspect food items might be that you wish to cut out (or add in) to your daily routine.
This book is excellent for those who need to keep track of what they eat for their health, and can be highly useful when looking back to see what repeat offenders keep ending up on your plate.
