The Paleo/primal approach to eating is anexcellent, common sense way of staying healthy, improving your health and losing the fat. It's probably been mentioned already, but it's a lifestyle rather than 'a diet'. I don't get these folk who 'go on a diet'. It's a lifestyle change they need to make, something which they can continue for the rest of their days.
I combine this approach to eating with intense, brief and infrequent weights and cardio workouts and plenty of walking. Works a treat in keeping me in shape and it's very sustainable.
