Today right after I lifted weights I went to Costco to buy my 10pound supply of chicken breast like usual and I also decided to buy a scale. I bought it b/c I really never knew how much chicken I eat per meal. So I cooked my chicken on the GF grill and then I put them on the scale. It weighted in at 18oz. Am I weighing this correctly? If not then wtf em I doing wrong? And how many grams of protein do u think I had in this chicken?
