No matter what your fitness goal is, you will eventually hit a plateau unless you log and track your food. We can have success in the gym, but fail in the kitchen, which results in stalled progress.
You have to log your food.
The good news is that apps like Lose It make this a breeze. Lose It has a barcode scanner to instantly scan barcodes on pre-packaged food, and a searchable database of just about anything you can think of eating.
