Have you ever tried so many diet regimes, yet had no results at the end of the week? Have you ever heard of the blood type diet though? Let us dive deep about that type of diet and how it may be affecting all your diet decisions…

Ready? Fasten your seatbelts 😀

The blood type diet theory was originated from the naturopath Peter J D’adamo, in his book “Eat right for your type”, D’adamo claims that there is a chemical reaction happens between the food you eat and your blood type. The reaction is caused by a factor called “Lectins” some sort of proteins found in foods, which have agglutinating properties that affect your blood.

According to D’adamo, that following diet designed based on your blood type, will help your body digest food more efficiently, lose weight and prevent some diseases.
