Good rule of thumb for portion size

Sometimes it's hard to tell, "how much IS enough for me?" If you don't know where to start, heres a good rule of thumb to follow:

 This is how it may look like.

1. Protein (poultry, red meat, eggs etc) - 1 palm size or 1 hand size
2. Carbs (brown rice, sweet potato etc) - 1 fist size
3. Veg (go for more greens like broccoli, bok choy, long beans etc) - 2 handful

If you think it's not enough, you can add more greens, greens are practically "free foods," them fibers shall fill you up more. You can make some tweeks to this measurement depending on your goal, some people are trying to hit that 1 digit body fat, so they would take out the carbs completely and replace it with more vegs.
