Pre-diabetic and looking to eat healthier…

So I’m a 6ft. 3 in. male weighing around 357 lbs and am 21 years old. I’ve been told I’m quite close to becoming a diabetic, and have had prediabetes for a few years now, as well as a fatty liver. I’m looking to change my life for the better before it’s too late. I need some dietary advice to help me get on track to eating healthier. I used to snack here and there during the day, but wouldn’t eat a real meal, and then some, till’ really late at night. I’ve changed the way I eat for the past 2 weeks or so and have been eating one bowl of oatmeal in the mornings, a low carb tortilla with a single serving of low fat sandwich meat with a little cheese for lunch, and nothing really too specific for dinner. Usually keeping it around 2,000 or less calories for the day. Any and all advice will be helpful.
