Boosting your metabolism isn’t about removing calories so much as replacing them. You’ve got to completely reengineer your eating habits if you want to succeed in creating a finely tuned metabolism that works for you rather than against you.
In order to do this, you’ll need to choose healthy food types that are actually nutritionally useful for you. When your metabolism gets to work and processes these food types, this actually burns calories in itself and is yet another reason why you need to provide a constant supply of nutrients.
Initially, don’t try to starve yourself, instead just make some simple dietary switches to create some immediate benefit.
