Brain power is characterized by how alert, energetic, and  concentrated your brain is in response to a task. Information in your  brain passes through neurotransmitters, which are manufactured by the  nerve cells using precursors. Different neurotransmitters will have  different impacts on your brain activity. For example, serotonin is the  calming neurotransmitter that usually makes you more relaxed, drowsy,  and fuzzy-headed. While dopamine and norepinephrine are  neurotransmitters that make you more alert, more attentive, motivated  and mentally energetic.
Food affects your brain power by affecting  the production of neurotransmitters in your brain. By supplying amino  acids, which are used as precursors to manufacture neurotransmitters,  and by affecting the entry of the amino acids into brain, foods can have  a significant impact on your brain activity. High-carbohydrate foods in  general tend to subdue brain activity. Protein foods, on the other  hand, can counteract carbohydrate food induced sluggishness. In  addition, foods and herbs can have effects on brain activity by  affecting blood circulation - the supply line of oxygen, nutrient, and  hormone to the brain.
Weight loss isn’t a linear event over time. When you cut calories, you may drop weight for the first few weeks, for example, and then something changes. You eat the same number of calories but you lose less weight or no weight at all. That’s because when you lose weight you’re losing water and lean tissue as well as fat, your metabolism slows, and your body changes in other ways. So, in order to continue dropping weight each week, you need to continue cutting calories.
