Hello there and welcome! Of course you can do this! Looks like you've had a great 1st day!
I'm sorry those diets haven't worked for you.
One of the things we can offer you is to tell you how many calories you should try to eat in a given day in order to hit your weight loss goals in the time frame you selected above. You have more flexibility in what you eat, but would have to be careful regarding how much of it you actually eat.
You're going to do great!
