If you need extra help being accountable over the weekend, schedule your weekly weigh-in for Monday morning. Knowing that you'll step on the scale at the start of the week can help you to stay accountable and be more aware of your weekend choices.
Even though you might "forget" to enter in something into your nutrition tracker ALWAYS remember that your body ALWAYS knows what you REALLY ate. Make sure you track EVERY bite!!!
For those of you with digital cable boxes, if you have an "On Demand" option, you will find a ton of free workout videos.
Almonds are a GREAT snack as long as you eat them in moderation (they are a bit high in calories). I keep almonds everywhere - at my desk, in the car, at the house. Whenever I'm hungry I'll grab 24 almonds and eat that SLOWLY with some water to tide me over until my next meal.
Freeze a few grapes and eat them as a snack. Very refreshing and very few calories :-)
