Part of eating healthy is in looking at what you eat now and making the 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 what it gives you in terms of nutrition. It is as much about a shift in mindset as anything else.
For example, if you are used to having a burger for lunch, it may be a good idea to switch to a tuna or chicken sandwich on granary bread. The principle is the same – meat, bread, seasoning – and if it seems a little tasteless in comparison then there is a lot you can do with pepper, paprika or a range of other light spices.
