i think that you have to find the way of eating that suits you. I am intollerant to a number of foods, including wheat and rice and sugar. I also find that carbohydrates such as grain and potatoes have a very unfortunate effect on my system so tend to leave them alone. I now pretty well stick to meat, fish, eggs, some cheese, fruit, nuts and vegetables with some butter and olive oil thrown in. My weight stays fairly stable and my energy levels stay reasonable. If I stray too far from this programme I end up feeling unwell. My blood pressure and resting heartbeat are both low and, in general, this diet suits me, although it might not suit anyone else.
