If you want to lose 1 pound per week, on average you'll need to cut 500 calories out of your diet each day to make up the 3,500 calories in that pound. A 3-ounce serving of roasted chicken breast contains about 170 calories. This is about 70 calories less than the same amount of roasted chicken wings. As you can see, just changing another meat for chicken breast isn't likely to be enough to lose weight quickly; you'll most likely need to make other dietary changes as well.

4 x chicken breast, 8-10 new potatoes cut small, 2 sticks of celery, one carrot, 2 onions (1 red, 1 brown), 2 cloves of garlic, chicken stock, salt, pepper, rosemary, thyme.
