It's always been normal for me to obsess over a certain food and for awhile eat almost nothing but that food. Unfortunately right now one of those foods is pomegranate ice cream... I eat the pint in one sitting and then don't feel like eating the rest of the day. I'm also obsessed with my granola cereal and eating that for most of my meals. I know I should have more diversity, it's just most foods seem gross to me at any given time. Eventually I usually overkill on a type of food and switch my obsession to another food (sometimes I don't want to have the former food for a very long time).
