The Guardian: A Certain Unnamed ND's Blood Type Diet Ineffective

here, 'ah...yeah':

001. at The Guardian,  Dr Zubair Abdulahi  writes in "Weight Loss And Your Blood Group: Myth or Science" (2019-10-27):

"what is a blood type diet? This was popularised in the late nineties by a naturopathic physician who published a book on achieving ideal weight and in living healthy. He discussed how eating according to your blood type [...] is best for your weight loss journey and overall health as some food types may cause diseases [...] for each blood type, he created a meal plan for how best to lose weight [...] this was thought to help increase energy, boots the immune system and improve overall health. How effective is the blood type diet? Research carried out to examine the effectiveness of the blood type diet revealed no benefits in using the blood type diet. There was no relationship found between weight loss and blood type. In fact, the meal plan may be harmful to your health if you have certain health conditions warranting special diets [...] basing your meals on a blood type diet is restrictive as many healthy food types are excluded. If you need an effective meal plan for any reason, speak with your dietitian. Weight loss has nothing to do with your blood type";

true that! The who shall not be named!  And the research that was promised by the ND?  We're still waiting and it has been twenty years plus...
