One key component to making testosterone in the body (AKA building muscle and strength) is cholesterol. Now obviously there is good and bad cholesterol but I’ll get into that in another post. The yoke of the egg is what contains all of the nutrients like potassium, cholesterol, sodium, vitamin A, D, B-12, C, B-6 and much more! The white of the egg is where the protein, mostly, is found. Another great part about an egg is on average they only contain 0.6g of carbs. So they are great for morning pre-workout meals.
