Can you explain what is spot reduction?

An unfounded belief. Spot reduction is a belief that a person can make fat go away from certain chosen parts of the body. But, the human body uses up fat for fuel from all parts of the body. Gender, sex, & hormonal status affect where fat builds up. Fat distribution varies from person to person, so it is possible to find people who have minimal fat in certain areas, to use in advertising claims about spot reduction.
