I have had similar experiences; I did a lot of water fasting, lost a lot of weight (50lbs over 18mos), and then after all that fasting the sugary things just were not as appealing. On top of that, I find it easier to go into water fasting if I've been in ketosis for a bit, which is difficult in itself. But for that, I've found it helpful to remove other dietary restrictions; I don't typically eat dairy, and the stuff I do like to eat in keto is often much more expensive than the beans and rice / peanuts/ fruit that are the staples of my diet when I'm not trying to force ketosis or fast. Eating nicer food (usually meats, lots of eggs, dairy) makes being that process easier.
