EAT OR EXERCISE FIRST?

i find if i dont eat beforehand im STARVING half way through my walk!

so i either eat my dinner early, then go for a walk about an hour later, and have a snack when i come home! Its usually either a small bunch of grapes or a yogurt. Some evenings i change it around and have my dinner after my walk, either way i need a snack before or after because im always peckish when im finished exercising!
