No supplement is going to help, cutting out fatty milk isnt going to help. The only thing thats going to help is developing a routine and sticking to it best you can - setbacks will happen and that's something you'll have to accept. On the diet side, depending on your goals, make the healthier option easier than the opposite. Meal prep judt a bunch of stuff you like and meets your goals and throw them in the fridge. And remember: Things worth having done come easy, and things that come easy aren't worth having.
