Think 1-2-3. Simple easy steps, starting with writing down your goal.
1. Undo bad if it comes in a bag, a box, or premade don't do it.
2. Make a healthy habit for 2 weeks
plan your meals. Breakfast lunch dinner.
Even if it is the same thing day after day, but it's healthy, then make it a habit.
3. Buy healthy if you don't have it in front of you, you won't eat it. Don't eat out.
