Exercising is a bad and a good idea, where we need natural food for a healthy living and the vitamins that our bodies need, otherwise is not going to be the way it should be, especially without proteins. In this case at least has to be natural eating to keep a diet for a definition and less eating of those unhealthy fat foods. It helps you as well keeping less hunger during the training and the whole day. When we do not have required food, then feel exceedingly hungry and start to eat much more and get more lipidized.  It's our choice what to put into our bellies and how to absorb the food on a daily basis. Better we care about ourselves, the better the results are going to be quite a bit in the near future. Myself, eating healthy and not, depends, but in the last days not much running to far for shopping.
