I keep the individual natural apple sauce cups in the refrigerator at work. They are 50 calories and satisfy a sweet craving. Also the individual sugar free jello cups which are only 10 calories. They save my life (and my calories!)
I love my stretchy bands and resistance tubing. I carry them in my big tote bag and use them when I have a few spare moments at work. I can easily do 10 - 15 minutes a couple of times a day. It's nice to be able to do at least some sort of exercise on a busy day.
Every time I feel like I want to eat a snack I drink a cup of green tea, no sweetener. It gives me something positive to do, no calories and is healthy. It's a choice I can feel really good about. Then if I still feel like I want a snack I eat a piece of fruit.
