Type O – Getting Down & Dirty

Because I’m an O and I want to remember this stuff, I decided to kill myself with the research about the O blood type first… Rest to follow when I have A.Full.Day. to myself again. Not too soon, but despair not, A-AB-B friends.

Type O was, according to some research, the blood type of the earliest humans (according to some other research, it wasn’t – I choose to believe it was. I have a poetic soul like that). The early Os were skilled hunters who subsisted on a diet of, to cut a long story short, (a) the meat of the animals they killed and (b) wild plants they picked as they travelled through valleys and forests (because I’m a nice person, you also get the link to one of my favourite book series of all times, which tells of valleys and mammoths and love between prehistoric people. I know it sounds weird, but it’s AWESOME. A total must read). So anyways, it seems that their great-grand children with the same blood type also thrive on diets which prioritise meat and green veggies. Type Os are at their best when incorporating intense physical exercise (i.e cardio) into their daily routines and animal protein into their diets.

Unlike the other blood types, Type Os muscle tissue should be slightly on the acid side, according to Dr Lam and Dr D’Adamo. Type Os can efficiently digest and metabolize meat because they tend to have high stomach-acid content (if you don’t know what that means, click here). A balanced Type O Diet should include lean, preferably organic meats, poultry, and fish (seafood in particular – if you can), and avoid dairy products and grains as much as humanly possible (again: I don’t believe balance diets should eradicate whole food groups). Os should eat eggs only in moderation.

Veggies (greens, mostly) and all fruits are considered to be beneficial. Because of the high acidity of their stomachs, Type Os should eat fruits of alkaline nature such as berries and plums (remember that lemons are acidic in nature but alkali-zing after they have been metabolized by the body, so they qualify – read more here).

If you want to lose weight as a Type O, kill most grains, breads, legumes, and beans. Why? Because:
(1) the gluten found in wheat germ and whole wheat products interferes with insulin efficiency and slows down your metabolic rate (simply put, how quickly you burn fat)
(2) certain beans and legumes (lentils, for instance) contain lectins that deposit in the muscle tissues making them less “charged” for physical activity
(3) type Os have a tendency to have low levels of thyroid hormone or unstable thyroid functions, which also cause metabolic problems. So better avoid foods that inhibit thyroid hormones (cabbage, brussels sprouts, cauliflower, mustard green) but increase hormone production (kelp, seafood, iodized salt)

Menu Ideas
Where does this leave us in terms of actual eating? (it’s nearly dinner time and my head is buzzing a little from all the table formatting…) The following menu ideas are taken from “Eat Right For Your Type“, I hope you find them as useful as I do!

Breakfast

(1) Two slices Ezekiel bread with butter or organic almond butter (2) Vegetable juice  (3) A banana (4) Green tea

Lunch

(1) Organic roast beef (2) Spinach salad (3) Apple or pineapple slices (4) Water or Sparkling water

Dinner

(1) Lamb and asparagus stew (2) Steamed broccoli and Sweet potato (3) Sparkling water or Herbal tea (4) Mixed fresh fruit (blueberries, kiwi, grapes, peaches) (5) Decaffeinated coffee

In summary: Type Os Work Best on High Protein Diet

  • Thrive on intense physical exercise and animal proteins
  • Do not do well with dairy and grain products
  • Hardy digestive tract
  • The leading factor in weight gain for Type Os is the gluten found in wheat germ and whole wheat products.
  • Type O have a tendency to have low levels of thyroid hormone and unstable thyroid functions, which cause metabolic problems and weight gain
  • Type O have high stomach-acid content, and so they can digest meat easily
