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.
To make this happen, our example person can: 1  Consume 2000 calories per day and do no cardio whatsoever. 2  Consume 2500 calories per day and do an amount of cardio that allows them to burn 500 additional calories thus ending up at the same 2000 they need to be at.
