We have all heard of low fat, low carb and high protein diets.

One Yale doctor says having too many flavors in our meals is keeping us fat.

Johnathan Link lost 20 pounds and lowered his cholesterol in the last year. He says it is because of the flavors he chooses. He is a follower of the flavor point diet.

Author and doctor, David Katz says too many flavors in one meal triggers your brain to want more food.

"When you're eating food that has that flavor, sugary foods, salty food, you turn on the appetite meters that respond to that flavor category. When that meter registers full, so do you, but if you have all of them turned on, if you're firing on all cylinders, you've got to fill them all up before you feel full,” explained Dr. David L. Katz with Yale Prevention Research.

Katz's plan involves theme days. On orange day, all your meals have some oranges in them.

He says key points are: Do not mix sweet and salty, do not eat foods with long ingredient lists, do not eat highly processed foods like fast food and do not cruise from snack to snack.

Pick one and have your fill.
