Sarcopenia is the loss of skeletal muscle accompanied by loss of strength or physical performance. Current consensus definitions place low muscle strength as the primary criterion, with low muscle quantity as confirmation — a deliberate reversal of earlier mass-based definitions.[1]

The reordering matters for how the topic is discussed in the context of weight reduction. A fall in lean mass measured by body composition assessment is not sarcopenia; a fall in strength or function is the finding that would be.[1]
