Locking In Starting Today

Hey guys! I (24F, 6'1" 189lbs) decided just tonight that for the next 30 days, I am going to cut processed/ added sugars and simple carbohydrates out of my diet. I have a decent grocery list going and have some ideas for recipes, but I would really love some recommendations from people who are actively living a healthy lifestyle. I also love sweet treats so recommendations in that department would be greatly appreciated.

I've been pretty down in the dumps since gaining weight due to birth control, but I decided that today is the day I start to take action because otherwise, it will always be tomorrow. Thank you so much in advance! I am very excited for this journey! :))
