With today's holiday celebration, food becomes an even more significant issue for those whose objectives are weight loss. The key is to not allow a single day to prevent you from continuing with your program.
Now I'm not saying that a 4th of July BBQ is an excuse to predict failure. You should take 100% responsibility for your choices. Create an easy to follow plan to overcome each situation.
Remember what the holiday signifies--independence. How will you chose to declare you independence? Perhaps by taking control of your choices.
