Fitness blog?

I'm thinking about starting a blog about fitness and dieting gluten free. There really isn't much out there in this topic that isn't "want to lose weight? Try a gluten free diet" yeah, well what about those of us that are gf and need to lose a few pounds (or 75 in my case) I'm setting goals and starting towards them. Maybe I can help a few others out as well. :)
