On my phone, how do I make my main screen my meals instead of this running feed?

When I open the app on my Android, the main screen displays calories left at the top and a long running facebook-like feed of stuff.

I would like to adjust the settings so the screen remains on my food "Diary" for the day. I am not interested in all the stuff in the running feed, just my meals and calories.

Is there a way to do this? I did not see anything in the settings.

Thanks!
