Having watched the Michael Moseley documentary again, about fasting, I'm freshly enthused to give it a go.
In many respects it seems too good to miss. Weight-loss, sharp decline in risk-factors and increased brain function. What's not to like? (Oh yes... the lack of cake I suppose).
It struck me that evolution took millions of years to get us in shape for a feast/famine existence, spending a few days tracking an Antelope across a dusty plain, before gorging on the juicy bits all weekend. Then the Industrial Revolution comes along, puts Burgers within easy reach, and we start overloading our cells with easy protein and growth hormones.
This fasting regime clearly seemed to agree with our pre-Industrial cells.
The link between fasting and increased brain cells/synapses was amazing, almost evolutions way of saying, "Can't find food? here's a bit more brain, try thinking harder".
