I used to be the same way, OP. Food was never important to me...I remember repeatedly going 36 hours in high school, without eating anything beyond a handful of skittles or a vending machine snack. I felt faint and weak, but eating was such a laborious chore that I often waited until I couldn't stand it before putting in the effort required. This makes most family gatherings, wherein everyone's excited to get together for 'good food' totally unappealing to me. I don't care for chocolate, most candy (the only motivation I felt during Halloween was purely statistical...how many pieces of candy could I net, haha), desserts or any other things people indulge in. For the past year, though, I've completely turned this mentality around as I've made my diet and nutrition an obsession to compliment my bodybuilding endeavors. Now, I eat specific amounts of specific food every three hours or so. I'm not going to lie, it's very difficult to keep on top of, even without the remotest temptation to eat something unhealthy...it's just the pre-planning that's required, every single day. I do feel healthier and happier on a more balanced diet, though.
