Protein in chicken breast, raw and cooked

Chicken breast is the default protein of anyone tracking macros, for one reason: it delivers more protein per calorie than almost anything else available in an ordinary kitchen.

The numbers, both states

खाना	मात्रा	कैलोरी	प्रोटीन (ग्राम)	कार्ब्स (ग्राम)	फैट (ग्राम)
Breast, skinless, raw	100 g	116	22.5	0	2.5
Breast, skinless, cooked	100 g	165	31	0	3.6
Thigh, skinless, raw	100 g	145	19.5	0	7.5
Thigh, skinless, cooked	100 g	209	26	0	11
Leg with skin, raw	100 g	190	18	0	13
Whole chicken, mixed, raw	100 g	160	19	0	9.5

Why cooked reads higher

Nothing was added. Chicken loses 20 to 30 per cent of its weight as water during cooking, so the same protein and calories are concentrated into less mass.

A 150 g raw breast finishes at around 105 to 115 g cooked and contains about 34 g of protein in both states.

This is the single most common source of error with chicken, and it runs in the undercounting direction: weighing 110 g of cooked breast and logging it against a raw entry gives 128 kcal instead of 182, and 25 g of protein instead of 34. The conversion factors for everything else are in should you weigh food raw or cooked.

Efficiency

Calories per gram of protein, which is the ranking that matters inside a calorie target:

• Chicken breast: 5.2
• Egg whites: 4.7
• Fish, white: 4.8 to 5.5
• Low-fat curd: 9.7
• Tofu, firm: 9.3
• Whole eggs: 11.4
• Full-fat paneer: 16.2
• Toor dal, cooked: 21

Only egg whites and white fish beat it, and neither is as filling or as versatile. This is why chicken breast is the default in every macro-tracking kitchen, and it is the comparison point for the vegetarian options ranked in vegetarian protein worth the calories it costs.

Breast versus thigh

Thigh meat is about 25 per cent higher in calories and 7.4 kcal per gram of protein.

That is still good, and thigh has two advantages worth weighing: it tastes better to most people, and it tolerates overcooking. Dry, overcooked breast is the most common reason people abandon chicken as a staple, and a slightly higher calorie cut that you actually eat beats a leaner one you stop buying.

The bone problem

Most Indian chicken is bought and cooked bone-in. Bone is roughly 25 to 35 per cent of the weight.

Weighing 300 g of curry pieces and logging it as 300 g of meat overstates protein by about a third. Use an entry that says "with bone", or estimate the meat at around 70 per cent of the purchased weight. This is the edible portion problem, and it appears again in calories in chicken curry.

How much you actually need

For a 70 kg person targeting 130 g of protein, chicken breast alone would be about 580 g raw a day. Nobody does that.

In practice it supplies 30 to 50 g across one or two meals — a 150 g raw breast at lunch is 34 g — and the rest comes from dairy, eggs, dal and the protein incidentally present in grains. The target and how to distribute it are in how much protein do you actually need per day.

What the cooking does to the calories

The meat is predictable. The preparation is not.

• Grilled or tandoori, yoghurt marinade: +20 to 40 kcal per 150 g
• Pan-fried in a teaspoon of oil: +45 kcal
• In a home curry: +80 to 150 kcal per serving
• In a butter chicken gravy: +200 to 280 kcal per serving
• Breaded and fried: +200 kcal or more

The protein stays roughly constant across all of them. Only the calories move, which is the same pattern as every other Indian dish and the reason how much oil is actually in your curry applies here too.

Practical notes

Cook a batch. Chicken breast keeps three or four days refrigerated and is the easiest way to guarantee that a protein target is reachable on a busy day.

Brine or marinate it. Twenty minutes in salted water or yoghurt makes a large difference to how it survives cooking, and it costs almost nothing in calories.

Weigh it raw, in batches, and note how much the cooked portion weighs. After doing that twice you will be able to log either state accurately without thinking about it.
