An estimated 60% of the human brain's dry weight is composed of lipids, or fat, making it one of the fattiest organs in the body. This high percentage of lipids is not merely for storage, but is fundamental to the brain's complex structure and function.

The human brain is composed of nearly 60% fat on a dry-weight basis, making it the body's fattiest organ. This fact provides a clear answer to the question, "Is the brain mostly fat or protein?", though the roles of both components are incredibly complex.

The human brain is comprised of an astonishing 60% fat by dry weight, making it the body's fattiest organ. This high concentration is a primary reason why brain matter is made up of fat, a vital component for its structure, function, and signaling capabilities.

Weighing approximately 3 pounds in the average adult, the human brain is composed of nearly 60% fat, making it one of the fattiest organs in the body. This remarkable lipid-rich composition is not for energy storage, but serves a fundamental role in brain structure and function, profoundly impacting our cognitive health.

The human brain is remarkably composed of roughly 60% fat, making it the fattiest organ in the body. This high lipid content, including significant amounts of cholesterol, is not a cause for concern but is fundamentally critical for the brain's structure, signaling, and overall health.

The human brain is often called the body's 'control center' and is remarkably dense with lipids. This claim, that the brain is 60 percent fat, is true, but it is a nuanced fact that relates to the organ's dry weight rather than its total mass.

The human brain contains about 25% of the body's total cholesterol, making it the most cholesterol-rich organ. While not made up of cholesterol alone, this waxy, fat-like substance is a fundamental building block for a healthy, functioning brain.

Myelin is a specialized membrane comprised of an extraordinary amount of lipids—up to 85% of its dry weight in the peripheral nervous system. However, the idea that myelin is purely made of saturated fat is a significant oversimplification of its intricate biochemical makeup.

While a popular myth claims the brain is 90% fat, the reality is that the human brain is about 60% fat on a dry weight basis, making it the fattiest organ in the body. This substantial lipid content, however, is not the same as body fat stores, and understanding its role is key to comprehending brain health.

The human brain is a remarkably complex organ, and a surprising 73% of its weight is composed of water. This fact highlights why staying adequately hydrated is a fundamental requirement for maintaining cognitive performance, mood stability, and overall neurological health.
