I too feel very comfortable with this way of eating. I still have weight to lose and should be on Wave 2, but am behaving more like I'm on Wave 3.
I've never been able to tolerate extremely sweet foods, always needed some fat to make it taste good.

So years ago when I cleaned up my diet because of a potentially serious health problem it wasn't a big deal to eat less sugar. And to be honest, at that time artificial sweeteners scared me even more than sugar so I didn't make any substitutions.
Unfortunately, over the years my eating slowly got worse and I've been trying to clean it up again. Once in a while I want something sweet, so I have it. Usually fruit satisfies my sweet craving. I may have plain yogurt sweetened with honey and sliced strawberries (yum!) or a bit of pure maple syrup on a protein pancake. On very rare occasions I will sprinkle some "sugar in the raw" on my cereal or oatmeal, but 99% of the time eat it plain or with fruit.
I think, to make a successful lifestyle change, we all have to do what works for us. And eat mindfully, knowing that some things might not be so good for us so eat them in moderation.
