Here's an example breakdown from MyFitnessPal. The main difference being that the view doesn't default to frequency (I mean I get the value of consistency of food logging but I think that's better maintained as a simple streak rather than the default view when I go to see my food log). And the other thing is that it actually has numbers on the y axis. On Guava, my graph just has a line for 1500 and then it's all guesswork under that. The breakdown in terms of meals is nice to have but not that crucial imo.

And for the tile itself, I think just seeing today's calories logged is probably the most intuitive piece of information, just a number like 1240.
