Blood Type Diet Plan

Blood type diet plan

D’Adamo’s book, Eat Right 4 Your Type is the source of the blood type diet plan. The idea is that human blood type is key to weight loss.

Selection of different foods to eat depends on if you are blood types A, AB, B, and O. D’Adamo groups together by ABO blood group, each type within this group having unique dietary recommendations:

  • Blood group O is the hunter, the earliest human blood group. A higher protein diet is recommended.
  • Blood group A is the agrarian or cultivator, a more recently evolved blood type from the dawn of agriculture. The diet recommends vegetables and no red meat. A more vegetarian diet.
  • Blood group B is the nomad and has a strong immune system and a flexible digestive system. The diet states that people of blood type B can thrive on dairy products.
  • Blood group AB is the enigma, the most recently evolved type. This blood type diet treats this group as an intermediate between blood types A and B.

How much can I lose on the blood type diet?

D’Adamo does not state how much you would lose on it but it would depend on how much food you restrict yourself from consuming.

How does the blood type diet work?

Blood type diet recipes
Here’s the science bit. The idea is that human blood type is key to weight loss. Lectins in foods react differently with each ABO blood type and with an individual’s secretor status. Lectins interact with the different ABO blood types and therefore the selection of different foods for A, AB, B, and O types is important to minimize reactions with these lectins.

D’Adamo bases his ideas on the ABO classification of Karl Landsteiner and Jan Janský and other tissue surface antigens and classification systems. In particular the Lewis antigen system for ABH secretor status is relied on.

Other blood type identifiers, such as positive/negative, or secretor/non-secretor play relatively insignificant roles. More than 90% of the factors associated with your blood type are related to your primary blood type, O, A, B, or AB and hence the diet focuses on this.
