Looking to get more active. Advice appreciated :-)

20F, 5’5”. Not too sure about my weight as I don’t weigh every day, probably somewhere between 115-118lbs right now.

I used to be really active pre-2024: did all the things. Soulcycle, running, barre, pilates. Then I fell into a major rut, gained a ton of weight (from 100 to 145). I lost that weight this year just by going back to a more normal diet, but I’m looking to add walking back in just so I don’t spend 20 hours a day in bed.

Started 3 weeks ago & I’ve worked up to 7-10miles/day, M-F. I take weekends off. I’m currently averaging about 1200 cals/day. I find that the exercise makes me lose my appetite like crazy so even that is a bit of a struggle. Once I get above 1000 i feel about to pop. Should I decrease the mileage? Or is this alright considering my weight is normal?

I’m not that keen on tracking my weight tbh, I’d really rather not do it ever. Also not really looking to lose weight either. I’m just trying to do anything that gets me out of my room. Would appreciate all thoughts and suggestions. Thank you :-)))
