Part of eating healthy is in looking at what you eat now and making some necessary changes to turn it into something healthy. Although this may initially seem like deprivation, it allows you to keep a similar eating pattern, but improve the nutritious value. It is as much about a shift in mindset as anything else.
For example, if you are used to having a burger for lunch, try switching to a tuna or chicken sandwich on whole wheat bread. The principle is the same – meat, bread, seasoning – and if it seems a little tasteless in comparison, then spice it up with some pepper, paprika or a range of other seasonings.
