Part of eating well is looking at what you are doing today and making the adjustments required to make that a healthier thing. While this can potentially feel like starvation, it helps you to sustain a consistent eating style yet to enhance what nutritionally it offers you. It is about a paradigm change almost as much as everything else.

For starters, it might be a smart idea to turn to a tuna or chicken sandwich on granary bread, if you're used to eating a burger for lunch. The principle is the same – meat, bread, seasoning – and in comparison, if it looks a little tasteless, there's a lot you can do with pepper, paprika, or a range of other light spices.
