High rbc with low mcv, mch, MCHC could represent either iron deficiency in a patient with polycythemia or something called thallasemia. The elevated plts are most likely due to a secondary event. I would suggest having iron studies, ferritin and hemoglobin electrophoresis performed for further evaluation. It is unlikely the results are related to your diet.

Low iron can be behind the abnormalities and if it is low the cause could be from low iron in diet from poor iron absorption or blood loss losing iron.

Yes, A low calorie diet could result in nutritional deficiencies such as low iron levels. High platelets 543 and low MCV 72 blood test could be consistent with this. A high RDW lab result(not listed) would also be expected. Either the iron is not getting in or the iron is bleeding out. Other cause of low iron are excessive period bleeding or bleeding from your Colon or gut.
