Protein in 100g chicken breast is more when you compare it with a whole chicken. This is simply because a breast portion is mostly protein, whereas there is a lot of fat in other parts of the chicken like thighs and wings.
Protein in 100g chicken breast: 30g.
Here’s what I consumed a few days back: Chicken breast with sweet potatoes and salad (by the way the quantity here is close to 200g which provides 60 grams of protein)
Protein in 100g Chicken [whole with skin]: 25g
Half Whole Roasted Chicken (with skin), rice, one-half fry, and spicy sauce): This entire meal will provide me with over 100 g of protein (whole chicken 300 grams = 75grams, and more chicken in bowl plus one egg)
The protein content may vary from nutrition software to software, but these numbers provide a good estimate.
Personally, when given a choice I usually go with the whole roasted chicken with the skin.
The fat in the chicken is largely mono-unsaturated fats, saturated fats (I am very fond of this type, learn more), and some polyunsaturated fats.
