First thing is to stop the sugar consumption. Sugar turns to fat. Fruit is a healthy food and will not make you fat and is an important food item to add in your healthy food lifestyle change.
I'm not big on eating sugary items. I would rather have salty items like chips and fries, although I don't really crave those things as much since I've been eating extremely well. I have noticed however that when I do get a sweets craving it is always at night. So what to do? I've just been ignoring that craving but being poor certainly helps. I don't have the money to go out and just buy something and I don't keep those things in my home.
I don't eat processed foods. I don't consume toxic sugar substitutes. Sometimes juicing an orange or eating half a fruit item does help.
I can't stress enough on the importance of reading labels. Look at the sugar, salt/sodium content of that food you are eating especially if it is coming from a box. High levels of salt or sugar is not going to help you reach your goals.
My marital art instructor always said, "Be AWARE!" That can also be applied to food... Always know exactly what you are eating. You are responsible for what you eat... you and no one else.
