I’ve been tracking my food using Ate. One of my favorite features in Ate is that you can setup questions to answer about the meals, and tracking pre-meal and post-meal hunger level is useful information to me. However, I didn’t like the options so I made this set of options combined with fun emoji that work really well for me. I have the same options for a pre-meal and post-meal question.

0 - Lost hunger 😶
1 - Irritable 😠
2 - Hungry 👍
3 - Satisfied 👍
4 - Full 👍
5 - Sluggish 😒
6 - Stuffed 😟

The goal is to stay in the 👍 values.
