This little cup allows me to visually see what a cup of food looks like. I can quickly portion out 1 cup of chicken, 1 cup of quinoa for a healthy lunch. They also have smaller versions so I can see a 1/4 cup of almonds.
To keep my water in balance I drink at least 4 of these at work. It is a 12 ounce cup so I am getting about 6 of my 8, 8oz glasses of water today. The water has really been the key to helping me keep full all day. Before I eat I chug as much water as I can, little Bob Harper tip (you will know this reference if you watch Biggest Loser).
