• Hands are portable. They come with you to work lunches, restaurants, social gatherings, etc.
• Hands are a consistent size, providing a consistent reference.
• Hands scale with the individual. Bigger
  people need more food, and tend to have bigger hands, therefore getting larger portions. Smaller people need less food, and tend to have smaller hands, therefore
  getting smaller portions.
• Hand-size portions can help you track food choices, nutrients, and energy simply and easily. This saves time-consuming and often unnecessary weighing and measuring, which most people don't need.

For each meal, you might begin by eating:

• 1-2 palms of protein-dense foods.
• 1-2 fists of non-starchy vegetables.
• 1-2 cupped handfuls of carb-dense
  foods.
• 1-2 thumbs of fat-dense foods.
