Negative energy balance is not a disease
We are all familiar with the term ‘negative energy balance’. It is often perceived negatively, and even sometimes discussed as if it was a ‘disease’. These connotations are most likely driven by numerous associations found between negative energy balance and risk of diseases during the periparturient period. It is also frequently assumed that negative energy balance is the consequence of a shortfall of energy supply relative to milk energy yield. Yet most, if not all, nutritional tentative aiming to abolish the negative energy balance have failed.
