I actually had/have the same issue. Getting my carbs in but my calories are way too low. Its getting better now though as I am less afraid to eat fats. I aim for 1500 a day. I usually get somewhere between 1100 to 1550 a day, but its going there, and YES I know you are never hungry lol. I am not a fan of mayo or butter but I am adding small amounts of mayo mixed with mustard to make a sauce for me and eat that with roasted chicken or turkey slices. I also add some flax oil, olive oil and flax seeds and try and eat more salmon.
Not to mention I have developed a cheese addiction I am trying to break. I think all the years of eating fat free fake cheese turned me off to it and now eating real cheese just tastes SO good lol I need to watch it.
