I(17M) am 300 pounds at 5’11. I just got out of high school and was mildly active for most the time(had weights class), wrestled on and off. I have virtually no knowledge on how to lose weight, however i know i can lose it as before when i was in 9th grade i went from 230-200 in 3-4 months before covid. I have very bad cardio, like i get winded going up stairs. a very bad diet(i struggled with food abuse from former stepdad) and can no longer do textures and get scared to try new foods. Most of my weight definitely resides in my stomach/torso. How long do you guys think it would take to drop down to 240-250 to start? Any advice on how to keep my relative muscle mass while being in a caloric deficit? It seems overwhelming but i know i need this for my health, and i gotta change.
