1500 is a lot to me lol The 6 month insurance mandated diet I had to do before my surgery was 1200 calories with 100 carbs and 80+oz of water a day. It get's easier to adjust as you go along. I ate pretty much what I wanted, just in much smaller portions, and if I knew I was going to go out to a restaurant or whatnot, I'd look at their menu ahead of time to plan what I would get. I also fell in love with the 100 calorie packs and Special K stuff. But when it came to regular meals, I just ate whatever. Drinking a lot of water helps with the hunger pangs in between meals, and negative calorie foods help for a snack too (blueberries, apples, etc are all negative calorie because they burn more than they're worth and are high in fiber). Then 2 weeks before my surgery, I had to do 800 calories and 60 carbs a day. Since I was on the mostly liquid liver shrinking diet, that wasn't so bad. I just spread my protein shakes out so it seemed like I was getting more. I'm more than willing to help if you have any specific food questions! Good luck!
