Calcium is water soluble, but not fat soluble. It is the fifth most dissolved ion in seawater. On the other hand, fat is soluble into calcium in the body. The calcium will exâ¦tract the fat from food in the digestive system, and they combine to form a foamy substance which is not absorbed by the body, and so the fat will be flushed out.
Studies show that it is about 20 percent of the resting metabolic rate, which is about 1,300 calories a day, not of the total metabolic rate, which is about 2,200 calories a day, so the brain uses roughly 300 calories.
â1,300 kcal over 24 hours = 54.16 kcal per hour = 15.04 gram calories per second. â15.04 gram calories/sec = 62.93 joules/sec = about 63 watts. â20 percent of 63 watts = 12.6 watts. So a typical adult human brain runs on around 12 wattsâa fifth of the power required by a standard 60 watt lightbulb.
