Lean meat is fat-free
Even the leanest meat contains some fat. You may need a magnifying glass to see it, but it's there nestling in among the fibres of flesh. Take a nice deep red lean fillet steak, for instance - about 5 per cent is fat. A skinless chicken breast is saintly by comparison - only about 2 per cent fat. The darker meat in poultry has a little more fat and anything with skin on it is fattier still.
