The brain, despite making up only 2% of your body weight, consumes about 20% of your total resting energy, or approximately 320-450 calories per day. This astonishing fact naturally leads to the question: do you lose calories when using your brain, and does it lead to noticeable weight loss?

Accounting for only 2% of body weight, the human brain consumes up to 20% of the body's total energy, so do thoughts use calories? The answer is more complex than you might think and surprisingly relevant to daily energy levels.

According to researchers, the average adult makes around 35,000 remotely conscious decisions each day, with a significant number of those concerning food alone. This constant mental exertion can lead to a state known as decision fatigue, explaining why a seemingly simple food choice can feel so overwhelming.

The brain consumes about 20% of your body's daily energy, despite making up only 2% of your body weight. This high demand raises a common question: Do you consume more calories when studying, especially during intense, focused sessions?

According to a study published in *Scientific American*, performing a mentally demanding task can lead to consuming hundreds of extra calories later in the day, despite minimal actual energy expenditure. This phenomenon reveals a surprising link between your cognitive load and your appetite.

The human brain, despite making up only 2% of the body's weight, consumes about 20% of the body's resting metabolic rate. This remarkable energy demand has long fueled the popular question of whether highly intelligent individuals or those engaged in complex thought burn significantly more calories than others. However, the reality of brain energy consumption is far more nuanced than a simple equation of "smarter equals more calories burned".

While the brain makes up only about 2% of your body weight, it consumes roughly 20% of your body's total energy, mainly in the form of glucose. This fact leads many to wonder: does brain usage burn calories, and can you think your way to a slimmer waistline?
