My girl is on a new diet. It's called Macrobiotics, and is basically a traditional japanese diet with miso, and all shapes/sizes of tofu/tempeh, organic soy and sea vegetables. A bit of fish, but brown rice instead of white rice.
At any rate, combined with exercise, she was already lean but has lost a lot of weight (the tough midsection/arse area) and she says she feels very healthy. Her skin is noticeably healthier as well.
Back on topic, the soy sauce that her diet recommends lacks alcohol. Many soy sauces use a little alcohol as a preservative. Supposedly the non-alcohol stuff is better.
