food portion plates

When I saw food portion plates, I was amazed too. However, When I read the details, I praised the people who has come up with this idea. My son has become an obese person. My wife and I are disturbed because of his eating habit. He takes too much rice and bread when he eats. I think this plate will educate him how much he should eat. If he succeeds in improving his eating habit, I am sure his weight will come down.
