Changing the demographic effects the serving goals for the next day. You can change the serving goals for the current day by deleting the current day. EatHealthier will automatically generated a new day for you. To delete the current day:
Tap on the "Day List" tab
Tap on the Edit button
Tap on the Delete circle on the left-hand-side of the current day
Tap the Delete button
Now go back to the Servings tab and a new day will be there with the new serving goals.
The current version of EatHealthier is designed for personal use. I am looking at multi-person use in a future upgrade.
