Traditional wisdom says that's nearly impossible at my age without "supplements" like "vitamin T".
I've found that IF is the real key for me.
I do one meal per day, and I can see all my nutrients laid out in front of me.
Aside from the other purported benefits of IF, this level of control I think is the main benefit to me.
I think that a lot of people don't realize how disconnected the feeling of hunger is from your actual (very minimal) caloric requirements.
Hunger is mostly a trained response, a production of ghrelin that's mostly a pavlovian response coupled with incredibly complex gut and psychological factors.
The hunger response can be trained away in about a week. I generally don't start getting hungry until around 6pm, when I've trained my body that it's dinner time.
Snacking, IMHO, is the single biggest weight loss killer.
