Lack of cravings doesn't indicate an eating problem.
With Bulemia, you binge on foods that you have denied yourself for a time and then purge (force yourself to vomit or use laxatives to get the food out of your system quickly or both) because you feel guilty for having eaten it.
With anorexia, you purposely starve yourself and often exercise excessively. Both conditions come with a preoccupation/obsession for being very, very thin as well as a distorted body image; you see yourself as fat when others around you feel that you are too thin.
You don't sound like you have either of those problems.
Quick weight loss in the beginning doesn't necessarily mean something is wrong, either. As long as you are eating enough and not purposely starving yourself, don't fret.

Lack of appetite is quite normal, especially in the early stages of low carb when ketosis is high and carbs are low.
The lack of cravings is a blessing that many of us welcome; to be free of the control that these foods had over many of us is a welcome gift!
If you don't particularly enjoy the foods that you are eating, how about experimenting a bit with seasonings and ways of preparing it to make it more appealing? Sometimes something as simple as baking or broiling a cut of meat instead of frying it in a pan will make a big difference in the taste and there is an infinite variety of herbs and spices that you could try for seasonings. Get creative!
