Lean protein is healthy, right? Not if you eat too much of it. If you are eating a whole chicken breast for dinner, you might be eating too much.
The recommended single portion of chicken is 3-4 ounces, about the size of a deck of playing cards. Some people use the palm of their hand as a guide. Depending on the vendor, some chicken breasts are twice or even three times the size of a recommended serving. The calories in chicken breast can add up and ruin your diet.
