&quot;My advice: eat when you are hungry, eat real food, forget about macros.&quot;<p>This is always my go-to response when people ask me about my diet.  If you simply eat only when hungry, and only eat real food, you&#x27;re going to be in decent shape on average.  There is a lot of detail and difficulty hiding behind those two simple requirements though.<p>For example, eating only when hungry implies that we stop eating when we are no longer hungry.  Avoiding binge sessions is sometimes very challenging.  And accepting a simple definition of &quot;real food&quot; can be surprisingly challenging.  Things that don&#x27;t make the cut:  Frozen pizzas, almost all fast food, even orange juice.
