Chicken Breast — 165 kcal

Chicken breast sits at the top of nearly every serious meal-prep list, and the numbers explain why: 165 kcal per 100 g, a towering 31 g of protein, and a mere 3.6 g of fat with zero carbohydrates. That protein-to-calorie ratio is virtually unmatched among whole foods, making skinless chicken breast the default building block for anyone chasing a body recomposition or a calorie deficit without sacrificing muscle. Every serving delivers all nine essential amino acids in proportions that rival whey protein concentrate, yet it costs a fraction of the price and keeps you full far longer.

What's Inside

Niacin leads the micronutrient roster at 13.7 mg per 100 g — roughly 86% of the Daily Value — fueling the NAD+ cycle that converts food into cellular energy and helps repair DNA. Vitamin B6 (0.6 mg, about 35% DV) is essential for synthesizing serotonin, dopamine, and GABA, the neurotransmitters that govern mood and sleep. Vitamin B12 (0.34 mcg) supports red blood cell production and myelin sheath integrity, while pantothenic acid (0.96 mg) feeds coenzyme A, the hub of fatty-acid metabolism. On the mineral side, selenium (27.6 mcg, 50% DV) powers glutathione peroxidase — one of the body's primary antioxidant enzymes — and phosphorus (228 mg) partners with potassium (256 mg) to maintain bone density and regulate fluid balance. Zinc (1 mg) and iron (1 mg) round out the profile, contributing to immune defense and oxygen transport respectively. Cholesterol sits at 85 mg, well within the range considered safe for most adults.

Getting It Right

The single biggest mistake people make with chicken breast is overcooking it. Pull it off the heat at an internal temperature of 74 °C (165 °F) and let it rest for five minutes — carryover heat finishes the job while the juices redistribute. Brining for 30 minutes in a simple salt-sugar solution transforms even a bargain-bin breast into something remarkably juicy. For a golden crust without deep-frying, sear in a screaming-hot cast-iron pan for three minutes per side, then finish in a 200 °C (400 °F) oven. Chicken breast's mild flavor is its secret weapon: it absorbs marinades like a sponge, so rotate between lemon-herb, smoky chipotle, ginger-soy, and chimichurri to avoid meal-prep fatigue. Store raw breasts in the coldest part of the fridge for up to two days, or freeze individually wrapped portions for up to nine months.
