Bold list item for entire list

Question

How do I make it such that all text in my list are bold by default?

Is repeating the many lines of \textbf the only way to achieve this?

\begin{enumerate}[label=\arabic*, parsep=10pt, font=\bfseries]

\item \textbf{List Item}
\item \textbf{List Item}
\item \textbf{List Item}
\item \textbf{List Item}
\item \textbf{List Item}

\end{enumerate}

Answer 1

Define a new environment:

\documentclass{article}
\usepackage{enumitem}
\newenvironment{bfenumerate}[1][]
 {\begin{enumerate}[before=\bfseries,#1]}
 {\end{enumerate}}

\begin{document}
This is a boldface enumerate
\begin{bfenumerate}
\item First
\item Second
\end{bfenumerate}
and this is a normal one
\begin{enumerate}
\item First
\item Second
\end{enumerate}
\end{document}

You can add any enumitem option also to bfenumerate, just call it, for example, with

\begin{bfenumerate}[label=(\alph*)]

for alphabetic enumeration.

Answer 2

Just use the font switch command inside the environment before the first item

\begin{enumerate}[label=\arabic*, parsep=10pt, font=\bfseries]
 \bfseries
\item List Item
\item List Item
\item List Item
  \begin{enumerate}\normalfont
  \item List Item
  \end{enumerate}
\item List Item
\item List Item
\end{enumerate}

the font option is for the appearance of the label (number) for the various items.
