But that's why there was nobody talking about it at the time.

And that's where I started to sort of bring it into the sort of public consciousness that this is a tool.

That's all it is.

Oh, absolutely.

I got attacked from all sides.

Doctors were coming after me.

Dietitians were coming after me.

Everybody thought I was going to do so much harm.

And the funny part was that

You know, as I think back, as I spoke to a lot of colleagues, a lot of colleagues would say to me, you know what?

I used to do that when I was in training.

We did that all the time.

We'd go 24 hours without eating because we're in the OR or we're in the ER or we are busy.

So we did that constantly and nothing bad happened.

And I remember thinking, you know what?

As a doctor, I actually tell people to fast all the time.

If you have to go for surgery, you need to fast.

If you're after surgery, you need to fast.

If you do fasting blood work, you need to fast.

So why is it that I'm actually telling people to fast all the time, and yet for weight loss, you shouldn't fast?
