Beginner Health??

This is what people call "Fad Diets" I've tried a ton of them over the years and each one promised to get the weight off and it did however once I went back to eating a normal diet I gained all the weight back. 2,300 cal is how much you would eat if you were doing a crazy amount of exercise everyday. If you live a less active lifestyle that's just going to cause you to gain weight.
I'm 23 years old, 237 lbs, 5'5"
I started at 244 and am now 237, my goal is 180 (or maybe lower if I feel like continuing to lose weight)
I live a low activity life and work out 2-3 times a week. It's recommended I eat about 1200 cal. You seem like you're in a similar area, so 1200-1500 would probably be fitting if you live a low activity life like myself.
On the other side of things, while 2,300 cal is a lot don't eat less than 1,000 a day. Your body will go into starvation mode and things won't end well. Any weight you gain by 'starving' yourself will be back, it did for me.
Anyway, I wish you luck and I hope you can find a healthy eating style that will fit you.
I just recently went pescetarian (vegetarian that eats fish) and this is probably the best change I've ever made. I also cut out any and all over processed junk food, fast food, as well as soda and chocolate. I highly recommend at least cutting out junk to anyone who plans on losing weight as that's been a big help for me so far.

Best of luck, and please feel free to add me and message me if you want more help/advice. I'm no professional but I can at least give you my honest opinion or maybe some links to stuff I've found helpful.
