Not everyone is blessed with a speedy metabolism. I have spent years researching and experimenting on how to lose weight and keep off. I have a solution that has worked for me, and many of my friends, which I will share with you.
It is important to avoid processed foods. These are difficult for the body to digest and metabolize therefore the body stores them as fat. Basically, if it comes prepackaged, it is processed.
Having said that, there are exceptions such as frozen vegetables and fruit. If you purchase frozen items, be aware they do contain preservatives. Read the label to see how many calories they contain per serving. Make sure the sugar and sodium contents are low.
