I like the idea of 5% increments - much easier to achieve and you feel like you've hit a goal each time. I do very low carb (no bread, cookies, root vegetables, potatoes, pasta, rice, etc) and have essentially cut out all sugar and artificial sugars except for Stevia. After a couple of weeks the cravings actually disappear!!
I focus on what I CAN eat and stay on plan with: lots of lean meat, seafood, eggs, lots of veggies with full fat salad dressing (watch the carbs and sugars on label).
Everyone's different, but it's way easier without the cravings.
