my doctor has prohibited me from eating beef because she said my bad cholesterol is ALMOST high (i'm 18 yrs old, both parents have high blood pressure, runs in the genes). she said i've been getting the bad cholesterol from beef even though it's lean. so can only eat chicken (i don't like pork too much) therefore i got a problem with fitday because i don't know how 4oz of lean chicken looks like. in the eating for size article it says that 4 oz of beef is like the size of the palm. do the same rule apply for chicken? thanks.
