My friend's mom is a nanny working in high-end homes in a villa community. She discovered a lifestyle pattern: wealthy people don't eat carbs, or they eat very little refined carbs. They eat sweet potatoes, Chinese yam, potatoes—not dumplings, buns, steamed buns, or rice. They don't eat heavily processed foods; basically just steamed, cold dishes, and grilled items. They won't eat deeply processed stuff like sausages or junk food. They eat fish, shrimp, free-range eggs, beef.

As for congee, they make it but then throw it away without drinking it, so they stopped making it altogether.

The homeowner is 55 years old but looks like she's in her thirties. She basically stays hungry—never eats until full. She maintains a great figure too.
