Out of the shadows to add my 2cents...
I talked to my doc (naturopath/nutritionist) about the blood type diet and she said that there weren't enough confirming evidence from other sources that this was true. Also, I purchased a little book about my blood type, then borrowed the book from the lib with all the stuff, and they conflicted! I thought it made sense to me after reading the little book, but the big book said nearly the opposite of what was writen in the other book. Same authors, etc. hmm. I decided, for myself, as well, that it just didn't have enough stuff that rang true for me. And there's so much out there, it's good to let things fall by the way side that aren't contributing to the overall picture.
Also, about fat v carbs - I just wanted to say that the diets are more alike than they are not. The basics, whole foods and unrefined stuff is there in both of them. And the low carb stuff doesn't say not to have grains, just have whole grains, and avoid refined grains. Some people do have alergies to glycemic grains, which includes wheat. And another thing about the fat is - to acknowedge the difference between bad fats and quality fats. Bad fats are of course the fried ones, because they're denatured and sometimes toxic. Other bad fats are the man made ones - the trans-fats, which are listed in the ingredients as hydrolated fats, those "cheaper" fats that have hydrogen added to them. Quality fats are sometimes listed as "oils" to distinguish them - but they usually aren't the cooking oils; evening primrose, borage, fish oils (but only if you can get quality, untained fish body oils, very hard to find). A lot of the "light" cooking oils just aren't that healthy. I use almond oil, peanut oil (but some folks are alergic to peanut), olive and avocado. Expreller pressed so they don't overhead while processing and defeat the purpose of cooking at lower temps.
I love bread, too. And it's not forbiden, it's just that even whole wheat bread will tend to have refined flower, w/whole what or whole wheat flower added so that it's soft and tasty. Read your bread labels, they are notorius for harboring those bad food additives, sugars and bad fats.
Avoid margarine and aspartame (nutrasweet) especially. Here's a link to a discussion about coffee that I circumvented to discuss aspartame and it's evils: Coffee Question
Also, I don't think that fruits are bad. I don't think most low carb diets forbid them during the long term plan, just the two week induction. Depends on the diet. I just think that folks tend to consider them interchangable with veggies, and of course they're different, and fruits are also very suseptible to environmental toxins. And are high in sugar content and low in proteins and complex carbs that would combat the glucose reaction. So, moderation is key.
Been enjoying keeping up with everything. I'm doing ok. Had to drop dairy from my pg diet, it was making me feel awful. Glad I figured it out. It's only been 4 days but I feel great so far and I'm pretty convinced that must have been what's going on.
