Loss of appetite

I'm hardly having an appetite right now. About 10 days in raw. Coming from being a vegan junk food addict and constant food noise this is good. But I know there's no way I'm getting enough calories. I am overweight. The first week I felt really energized but I feel really lethargic right now but I am on my period. Barely any bleeding and no pain which is soooo amazing! (But also a little weird like nearly no blood at all) Do you listen to your hunger cues or eat proactively to get enough calories? My eating is looking like juice, fruit, salad, maybe more fruit.
