This is easily mistaken to be the same as keto life since a lot of people think all their weight is composed of fat. This is not true. Yes, a person's weight is composed of his or her fat, but overall weight is total accumulation of more than just fat (which will be touched upon later on when keto life is discussed). Fat is not the only factor which makes a person heavy. Fat is, however, the most dispensable and expendable excess of the body which can be lost to make a person's weight lighter, without his or her body being unhealthy.
