Removing some content from profile page

If there is some content on profile page you dont want to display, for example, you want to remove user summary, you can do it by using hook_profile_form

/**
 * Implementation of hook_profile_alter().
 */
function helper_profile_alter(&$account) {
  //var_dump($account->content);
  unset($account->content['summary']['#title']); //remove summary
  unset($account->content['summary']['member_for']); 
}
