I'm not sure how you plan to use it or what you're doing with $_GET['callback'] , but the main issue is that you need to append elements under a new array under data :

for($x=0;$x<=4;$x++){
    $RESULT["data"][$x]["name"] = "Name" . $x;
    $RESULT["data"][$x]["calories"] = "calories" . $x;
    $RESULT["data"][$x]["fat"] = "fat" . $x;
    $RESULT["data"][$x]["protein"] = "protein" . $x;
    $RESULT["data"][$x]["carbohydrates"] = "carbohydrates" . $x;
}
echo json_encode($RESULT, JSON_PRETTY_PRINT);

So:

$RESULT["data"][$x]["name"]

Not:

$RESULT["data"]["name"][]
