1. The weight-loss plate
How smart is this dish — it takes the guesswork out of portion control! Designed with a pattern divided into quarters, and backed by research from Harvard, Stanford and the Mayo Clinic, it helps you calculate the perfect amount of food to eat. Just stay within the boundaries to get 25 percent protein and whole grains and 50 percent vegetables.
Bonus: Research says it can cut calorie intake by 59 percent.
Plate, $99, Slim & Sage.
