<?php $counts = bp_follow_total_follow_counts( array( 'user_id' => bp_loggedin_user_id() ) ); ?>

Display following count:
<?php printf( __( '%d', 'bp-follow' ), (int)$counts['following'] ) ?>

Display follower count:
<?php printf( __( 'Followers <span>%d</span>', 'bp-follow' ), $counts['followers'] ) ?>


Note: if you change bp_loggedin_user_id() to bp_displayed_user_id() you can show the counts on member's profile pages instead of displaying the count for the logged in user.
