People undertake severe dieting to reduce weight but too few calories can also impair brain function and many studies have linked dieting with distraction, confusion and memory impairment.
The best mantra is to eat proper foods to keep the brain alert along with a workout for half an hour. And a good sleep is also necessary to keep the brain refreshed.
A low glycemic diet-high fiber, with moderate amounts of fat and protein is broken down more slowly in the body than high glycemic foods, such as sweets and white starches. A steady pace of digestion gives a more reliable flow of energy to the brain. Essential fatty acids, such as Omega 3s, are critical to brain function, so eat more fish.
However, there should be an exercise regime to keep fit. One need not hit the gym, but simple tasks like brisk walking, push ups, crunches and cycling will be enough to keep you from gaining excess weight.
