Fat is stored when food is consumed and not burned. So if you have a relatively stable weight, then this is simply not an issue. If you are going to gain weight, then you will have fewer fat cells in any areas that were treated, so proportionately fat will go more to other areas. When liposuction is done to put someone into better balance, then this isn't a problem, because they will gain or lose weight in a more proportional manner. The people who have trouble with fat going elsewhere were people who were overweight and had liposuction in one or two areas that weren't necessarily disproportionate. When those folks gain weight, then the fat does seem to go somewhere else.
