In what is, admittedly, the least-tested part of their thesis, Dr Unger and Dr Scherer argue that other cells react to this increase in leptin concentration by becoming resistant to the hormone's effects. That, in turn, stops them oxidising lipids and opens those cells to lipids' toxic effects.

Glucose and glutamine are both essential for cell growth, and it was long assumed they operated independently, but Ayer's research shows they are inter-dependent.
