I saw the thread on childhood obesity. An Australian friend recommended this book. While it is clear that it is written to the unique Ozie sense of humour it is applicable anywhere. It combines a look at a typical family with an overweight little boy and the struggles they go through to make lifestyle changes, with very useful practical tips. Most of us who are living a busy life can relate to at least some of it.
