When I want comfort food I buy Maltesers. I like all chocolates but especially those. You can eat them and because they're so light you can convince yourself that they are not actually that fattening.
A vegan diet takes care of most of what we need to do. But you'll also want to minimize the use of oils generally because while olive oil and other vegetable oils are better for your heart than chicken fat they are as fattening as animal fats.
My book 'Trust Your Heart' which is the story of my life will be followed by 'Singing Lessons' a memoir of love loss hope and healing which talks about the death of my son and the hope that has been the aftermath of the healing from that tragedy.
