Too few miles and too much food

I weighed 166 today. Yikes! I saw that once last summer, but this time I don' think it's a blip as I've seen a trend lately. I haven't weighed 166 in 3 years when I was running 40-50 mpw, which is, not coincidentally, what I've been doing lately. Ugh. Since I won't be running more than that for quite a while, I guess I need to figure out how to eat less. My diet is atrocious anyway, so maybe this will inspire me to eat healthier.
