Two weeks down ... four weeks to go!
At this point in the challenge you are hopefully seeing some interesting changes. You have given your taste buds time to reset, so the cravings you may have been having two weeks ago are also hopefully starting to subside.
Are you sleeping better? Do you feel more energized? Are you seeing any positive changes in your body physically? It is amazing how food affects us, both positively and negatively, so pay close attention to changes you are seeing and feeling.
