Well, I think philosophically it's a bit hypocritacal to not eat chicken, but eat chicken soup, as an example. The soup is made from the discarded carcasses of the animal, flesh removed, but bones intact, and organs, heads, feet....
I suppose if you are okay with that, it's fine by me. Personally, I prefer a balanced diet, including meat, in small portions, lots of fresh vegetables, fruit, nuts, grains and pulses, and eating small portions more often during the day, 5-6 servings, rather than three big meals. The important thing is variety, and getting your nutritional needs. The macrobiotic diet can work, but it's a tough road, not right for everyone.
