I heard her talking about it on television and is sounds interesting. What's the name of this diet and what does it consist of?

are you talking about macrobiotics?

there's a lot of info about it online. go to www.google.com and type in macrobiotics and do some reading on it. from what i understand you eliminate processed foods (flour, sugar, etc.) and nightshade veggies (potatoes, eggplant, tomatoes); you eat only the foods that are available to you locally and in-season; and you eat some fish.

i think it consists mainly of a lot of brown rice.

Macrobiotics was discussed extensively in the following thread:
