Not anymore. More recent research has failed to find any real benefits to intermittent fasting, at least for people who are already at a healthy weight. And it seems to have some negative effects for body composition.
Note I used periodic instead of intermittent for a reason. I seem to recall he was recently for something like a day a day and a half fast per month. Don't follow him that closely, did he move away from that too?
It's generally uncomfortable to share meals with people who aren't eating. It's deeply ingrained in many cultures to "break bread" in a way, so I think that's why it can be perceived as rude.
