I don't know about you but every year I start out with the same resolution, loose weight or not gain weight. Take a look at my family blog I completely fell off the bandwagon yesterday :(
What I find is lower cal and fresher ingredients are more expensive at the grocery store but not more expensive at your locals farmers market.
If you have a local farmers market take a look around and visit and make part of your weekly shopping routine for your fresh veggies (if cheaper).
I need your help fellow frugal readers, I am looking for great low fat recipes and tips that help you stay fit. Any great products you think work great?
