As a scientific fact, our brain contributes to only 2% of our body weight but it absorbs 20% of our total calorie intake. To function properly, it needs a constant supply of glucose and fat. The one mistake we make is eating fast food and foods rich in sugar, which releases glucose instantly which results in a sugar high and increase in productivity but then but then the sugar level drops just as suddenly as it occurred causing a slump. To keep your brain active throughout the day and to increase your productivity, consider eating healthier.
