Hi I’m also 19 and about 5’6:5’7 and started at 290.8lb. I’m also dealing with binge eating but it’s got a lot better with intermittent fasting. I would suggest starting with 16:8 fasting and pick a window that works for you, e.g: (8am-4pm), then you can eat when you want between that. Try and make it as healthy as possible, but if you focus on keeping a sustainable deficit that should work. You could also add in light exercises like waking if you like. Before you know it you’ll be at the low 200’s! :)
