Your ETM Account contains all of the tools for meal planning using your own account. If you want to follow meal plans yourself or use your own account to create meal plans for others this section of the sidebar will help you accomplish that.
Your Planner is where you can access the meal plan calendar that all premium accounts have if you wish to plan for yourself or prefer using the calendar to create saved plans for your clients.
You can also access your grocery list for the foods in your calendar.
Preferences contains the settings that affect generating meal plans on your account. You can also open these on the Manage Clients screen by clicking "Edit your preferences" on the user "You".
The Foods section is where you can search for foods to add to your plans, as well as manage collections and recurring foods on your account.
