What one serving looks like
About 100 g of cooked chicken breast is a palm-sized piece, a little thicker than a deck of cards.
Where it fits in a 1,200 to 1,600 kcal day
At 165 kcal, one serving is about 10 percent of a 1,600 kcal day and about 14 percent of a 1,200 kcal day. This is the leanest common protein, so people often build meals around it. One piece at lunch and one at dinner gives a lot of protein without taking much of the calorie budget.

How cooking changes the number
The value is for roasted breast with no skin. Frying, butter and heavy marinades add calories, while grilling does not.
A swap to try
Try Boiled egg. Eggs are cheaper and quicker if you do not want to cook chicken every day. Boiled egg (1 egg, about 50 g) comes to 78 kcal, which is 87 kcal less than 165 for roasted chicken breast.
Who might want to watch it
Make sure chicken is cooked through. People on a low protein diet for kidney reasons should follow their doctor.
