Well done for getting started. You are doing the right thing trying to get on top of the cravings and getting started on it.
I've just done 3 months of healthy eating after a lifetime of biscuits and chocolate and crisp grazing. I used to constantly crave food but particularly when stressed. The biscuits would just call to me.
After a health scare, I've cut out all processed sugar.
If it helps you to know, I have oats and nice fruit for breakfast, with milk (other cereals can have lots of sugar), brown bread sandwich and a banana for lunch, usual good dinner though using as much protein n veg as I can and potatoes or rice rather than pasta, then fruit afterwards.
And water, lots of water plus walks in-between.
And the cravings have stopped! But it has taken me years to really see that I needed to do this, and that I could do this, so you are ahead of me. I kinda knew before but really never believed I could.
Best of luck to you. (I also find it helpful to calorie count. Makes me feel in control. I have 1500 a day, every day and have a great spreadsheet, which gives me a sense of achievement as I can tick each day off. (Also helped me to discover that quiche is much higher calorie than I ever would have guessed. Oops)
