Klenner protocol link
Klenner food notes - I include the info in the following 2 points, because it contradicts sources who suggest avoiding eggs.
16) Make certain that the hemoglobin is at least 13 grams.
17) High protein diet with two to three eggs for breakfast.
IMHO eggs are a great whole food if eaten in a balanced way. yes i did eat two eggs per day for breakfast while i was on this regimen, but that is far from the norm. usually i have 0-1 eggs per day. rarely two these days.
i think protein is the point of the recommendation. If protein is low hemoglobin levels can drop.
THE ROLE OF DIETARY PROTEIN IN HEMOGLOBIN FORMATION (rat study)
"The foregoing experiments taken as a whole offer strong evidence that an adequate quantity of dietary protein is essential for normal hemoglobin formation in the rat and that the caloric intake is of minor importance. The mild chronic anemia occurred in all animals fed the low-protein (lactalbumin) diet, whereas a normal blood picture was found in rats given the same amount of diet containing an adequate quantity of protein but a restricted amount of calories. Furthermore, the chronic "low-protein anemia" developed in spite of an increased intake of calories. Further evidence that the observed anemia is due primarily to the low-protein intake was obtained in the group of "low-protein" rats realimented with an adequate amount of protein but with no change in the intake of calories, minerals, or other dietary constituents. A prompt remission of the anemia resulted in these animals."
FYI from mayo clinic:
''A low hemoglobin count is generally defined as less than 13.5 grams of hemoglobin per deciliter (135 grams per liter) of blood for men and less than 12 grams per deciliter (120 grams per liter) for women."
