Does Cole advocate for shorter / weekly fasts over long ones like 30-40 days ?

Im 5’9 230 M and want to be 140ibs, I was thinking I should do weekly fasts like 5-6 days a week followed by a 1 / 2 day reefed, since it would be easier to make it a routine once I got in the habit of it, instead of trying for 40 days and failing not to mention the reefed syndrome.
