T is for Tools.
There are all sorts of items out there to help a person with their weight loss, whether it be to keep track of calories or carbs or any combination of nutrition and exercise.
I use my WW eTools on the computer, there are all sorts of progress reports I can use to track how I'm doing. I also have my WW mobile app on my iPhone, although I learned quickly that the WW barcode scanner app is wrong. I scanned a couple things that I had already knew the Points value for and it was wrong. So that ticked me off a bit. I also have measuring scoops for portion control and a digital kitchen scale that can switch between ounces and grams.
Everyone has their own methods that work best for them, either a simple notebook and pencil, a fancy website or whatever - tools help!
