I've utilized a notepad for food journaling, water consumption, and exercise.

Last night I had a very tasty dinner. I had a big salad with powerhouse greens (kale, spinach, etc), cucumbers, baby carrots, water chestnuts, shredded cheese, and croutons...1/2 C of baked beans, and a veggie patty with salsa and sour cream. It was very filling.

I've also bought apple cider vinegar to mix with water to help with weight loss.
