The yolk drives the muscle advantage. Whole vs whites (van Vliet et al., Am J Clin Nutr 2017). Per 100 g yolk: 317 kcal, 15.9 g protein, 26.5 g fat. Yolks carry most of the fat and calories — one yolk is about 17 g.
How should I track Chicken egg yolk (boiled)?
Chicken egg yolk is high in vitamin d. Eggs are simple to track, but size matters more than you think. A "large" egg can range from 45 to 70 g without the shell, which means calorie content varies by up to 50%. Research shows portion estimation errors reach 50–200% for protein-dense foods (Almiron-Roig et al., Appetite 2013). For accurate tracking of Chicken egg yolk, crack and weigh on a kitchen scale — it takes two seconds. Cooking method matters too: a boiled egg is roughly 70 calories, while fried in 5 g oil it jumps to about 110. Log cooking fat separately.
