First of all, welcome! Hope you find this site as useful as so many other people have.
My main tip would be to plan all your meals/ snacks/ everything you eat. It only takes about 15 minutes the night before and can really help avoid going over in calories through one excessively large meal. You can also make sure you are a) Getting a good balance/ variety of foods that are still in your budget and b) are able to enjoy some of the things you like still, in moderation. It also really removes the temptation to eat something if you know it's not on your "list" for the day.
Good luck on your journey!
