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.
For exampleâ¦. You could eat 2400 calories per day and burn an average of 400 calories through exerciseâ¦. Or you could eat 2300 calories per day and burn an average of 300 calories per day through exerciseâ¦. Or you could eat 2200 calories per day and burn an average of 200 calories through exerciseâ¦. In the end, the net result is the same.
