Hi Ritter,
Interesting. I had my best weight loss doing something a bit Adkinesque some time back. It is called the Blood Type Diet by Peter D'Adamo. The author backs up his premise that diet should be tuned to blood type by throwing in some evolutionary type arguments/history related to the supposed origin of different blood types (garnering a pseudo-science label from some), but aside from this caveat, I had no problem with it and had good results. Here is a quick summary:
Type O blood: A high-
protein diet heavy on lean meat, poultry, fish, and vegetables, and light on grains, beans, and dairy. D'Adamo also recommends various
supplements to help with tummy troubles and other issues he says people with type O tend to have.
Type A blood: A meat-free diet based on
fruits and vegetables, beans and legumes, and whole grains -- ideally, organic and fresh, because D'Adamo says people with type A blood have a sensitive immune system.
Type B blood: Avoid corn, wheat, buckwheat, lentils, tomatoes, peanuts, and sesame seeds. Chicken is also problematic, D'Adamo says. He encourages eating green vegetables, eggs, certain meats, and low-fat dairy.
Type AB blood: Foods to focus on include tofu, seafood, dairy, and green vegetables. He says people with type AB blood tend to have low
stomachacid. Avoid
caffeine, alcohol, and smoked or cured meats.
My wife is AB and I am O, she loved the Macrobiotic diet that was in vogue many years ago (I hated it). She can go vegetarian or light on meat if need by, I have got to have animal protein. Anyhow, type O is supposedly the oldest blood type (if I am remembering correctly) and does best on hunter/gatherer foods. So, heavy on meat/fish/eggs, etc. plus veggies and fruits. Light on items that were the result of the development of agriculture and the domestication of cows, etc. such as beans, grains and dairy. So, plenty of animal protein, veggies and fruits and avoid the rest. Hmmm. Maybe I need to do this again. I need to lose about 30 lbs.
Cordially,
S&S
PS--My initial reservation about the Carnivore diet is that you better be prepared for constipation unless you can slip in some roughage somehow.
PPS--Just for curiosity sake, I'd be interested to hear from people who have different blood types in terms of their success (or lack thereof) in terms of vegetarianism, etc.
