Hi Mrs Bella, I have Dr Michael Mosley's book, the Clever Guts Diet. The main theme is eating a varied diet with loads of vegetables, but a wide range of vegetables. He also suggests kefir which I love, so I have that a few times a week.
I agree with you that we have to keep moving. For me, the health benefits of strenuous exercise outweigh the alternative, which would be about 4kg lighter but with no energy to do anything.
