Feeling Negative

A friend and I have been training for a sprint. Not much has been happening in the weight loss department for either of us--even though we have ramped up our exercise routine a lot. It could be that we are building muscle. I've noticed my energy level is higher and that I feel better overall since we've been training. We've thrown around a couple of ideas for dietary changes and decided to stick to the Word of Wisdom as our basic tenant.

A colleague at work told me about negative foods--foods that essentially have no calorie input because they require more calories to consume them than they hold. Not the first time I've heard about it, but I'm intrigued.
