A diet log is a useful tool for anyone trying to make changes in their eating habits, lose weight or simply lead a better lifestyle. It is a way to keep track, monitor and then review the foods and drinks one consumes on a daily basis. The information can give one great insight in to times they eat when they should not, key one in to foods they turn to time and time again that may not be the best choices and simply help one as they strive to make good food choices.
