How Many Calories Do 100 Grams Of Chicken Breast Have? | Clear Nutrition Facts

Calories In 100 Grams Of Skinless Chicken Breast — Raw Vs Cooked

Per 100 grams, raw boneless skinless breast averages ~120 kcal and ~22.5 g protein. After cooking, water evaporates and the same 100-gram cooked portion is denser: ~157 kcal and ~32.1 g protein. These figures come from datasets built on USDA FoodData Central entries and reflect typical retail chicken with minimal seasoning or brining.

Why Numbers Shift When You Cook

Heat drives off moisture. Weight drops, but the protein stays, so protein per 100 g goes up. Fat stays low for breast meat unless you add oil, skin, or breading. That’s why pan-seared breast cooked in oil will come out higher than dry-grilled pieces even at the same doneness. If you’re logging food, weigh the meat as eaten and match the database entry to the state—raw or cooked.

Fast Reference: Per-100-Gram Values

Type (100 g)	Calories (kcal)	Protein (g)
Skinless Breast, Raw	~120	~22.5
Skinless Breast, Cooked (Grilled/Roasted)	~157	~32.1
Breast With Skin, Roasted	~165–197*	~29–30

*Range reflects method and skin/fat retained; lean roasted breast entries cluster around ~165 kcal per 100 g, while versions with more retained skin/fat reach ~197 kcal.

Portion Sizing Without Guesswork

Labels list ounces, cups, or grams. For lean poultry, think in grams when you want precision. A palm-sized piece after cooking usually lands near 85–120 g, but weigh to be sure. If you’re budgeting calories for a day, snacks and sides fit better once you’ve set your daily calorie needs.

How Cooking Method Changes The Math

Dry-heat methods like grilling or baking keep calories close to database values. Air-frying sits in the same ballpark when no oil is added. Breaded or deep-fried breast jumps because batter and frying oil add energy. Chain-style fried breast shows ~268 kcal per 100 g, far above plain roasted breast entries.

Safety And Doneness

Food safety matters as much as macros. Poultry should hit 165°F (74°C) in the thickest part. A quick-read thermometer removes guesswork and helps keep meat juicy by avoiding overshoot. The CDC lays out clear handling steps—separate raw chicken from ready-to-eat food, skip rinsing, and clean surfaces.

Protein, Fat, And Micronutrients You Actually Get

Skinless cooked breast delivers ~32 g protein per 100 g with negligible carbs and ~3 g fat. Minerals ride along—phosphorus and potassium in useful amounts, small amounts of iron and zinc, and B-vitamins like niacin. Values vary with brand, solution-injected products, and how far you cook past 165°F.

How Much Protein Do You Need?

The U.S. Dietary Reference Intakes set the adult baseline at 0.8 g per kg body weight per day. Many active people aim higher, but the baseline helps you estimate meals. An authoritative summary from the National Academies confirms the 0.8 g/kg benchmark used in dietetics and sports references.

Raw Vs Cooked Logging: Pick The Right Entry

Databases list separate items for raw and cooked states. If your scale reads 150 g of cooked breast on the plate, choose a cooked entry; if you only weighed raw meat at 200 g before grilling, pick a raw entry. Per-100-gram raw breast shows ~120 kcal; cooked entries cluster near ~157 kcal when no fats are added.

Smart Ways To Hit Targets With Chicken Breast

Lean poultry helps cover protein gaps without bumping calories much. Pair with fiber-rich sides and a small amount of oil for flavor. Keep cooking simple: salt, pepper, garlic, and a squeeze of lemon. Resting the meat for a few minutes keeps juices inside and keeps the texture tender.

Simple Cooking Blueprint

Oven-Roasted

Preheat to 220°C/425°F. Pound to even thickness, season, and bake on a rack for 12–16 minutes until 165°F in the center. Let rest 5 minutes. This method keeps values near the plain roasted entry (~165 kcal per 100 g).

Grilled

Medium-high grill, light oil on grates, cook 5–7 minutes per side for cutlets, to 165°F internal. Plain grilled breast sits near ~157 kcal per 100 g.

Poached

Simmer gently in salted water with aromatics until 165°F. Poaching keeps fat gain minimal and makes shredding easy for salads and wraps.

Method And State Comparison (Per 100 Grams)

Preparation	Calories (kcal)	Notes
Raw, Skinless Breast	~120	~22.5 g protein; log as raw if weighed before cooking.
Cooked, Plain Roasted	~165	Lean entry for roasted breast without skin.
Cooked, Breaded/Fried	~268	Extra calories from breading and oil.

Frequently Missed Details That Skew Your Count

Brined Or “Enhanced” Breast

Packages injected with a salt solution hold more water and sodium. The weight includes that solution, so per-100-gram cooked numbers can land a touch lower in protein and a touch higher in sodium. Database entries sometimes call this out with “enhanced” in the name.

Oil, Marinades, And Sauces

One tablespoon of oil adds more than 100 kcal to a pan or bag. If you sauté, account for a fair share of oil that actually coats the meat. Thicker sauces stick more than thin marinades.

Skin On Or Off

Keeping the skin pushes calories up. Entries that keep more skin and rendered fat show higher energy per 100 g than plain roasted breast without skin.

Putting It To Work In Meals

Use pre-portioned cooked breast for bowls, wraps, and salads. Combine with whole-grain rice or quinoa and a load of vegetables, then add a spoon of yogurt-based sauce. The plate fills out, protein lands where you want it, and calories stay predictable.

Safe Cooking And Storage

Hit 165°F in the center, refrigerate leftovers within two hours, and reheat to steaming. The federal food-safety pages spell out the same target temperature and cross-contamination steps you can follow in any kitchen. CDC guidance for chicken is a handy single page.

Quick Answers To Common Calorie Checks

Is 100 Grams Of Cooked Breast Good For A High-Protein Meal?

Yes—roughly 32 g protein for ~157 kcal is a strong protein-per-calorie ratio when you’re building a plate around lean meat.

What If I Only Have Raw Weight?

Use a raw database entry. A typical 200 g raw portion yields ~150–160 g cooked if you stop right at 165°F. Your exact yield depends on thickness and time on heat. Raw per-100-gram entries sit at ~120 kcal.

How Do These Numbers Fit Into Daily Protein Targets?

Most adults can start with the 0.8 g/kg baseline from the U.S. DRIs and adjust based on goals and activity. A 70-kg person lands near 56 g per day; two 100-gram servings of cooked breast would cover that.

Dial In The Details And Keep It Simple

Weigh the portion you eat, match raw vs cooked entries, and aim for the center temperature that keeps meat safe and juicy. If you want a deeper dive into your overall daily plan, you might like our light guide on calorie deficit basics.
