Right.
21:22
Um, saying that I forged a career out of promoting meat is just categorically wrong.
21:28
Um, what they seem to miss out, they labeled me as a sort of journalist stroke author.
21:33
Um, I'd say I'm a public, um, health PhD researcher, analyzer of academic articles, dissector of academic articles.
21:43
So I think they've got all of that wrong.
21:45
Um, but this idea that I've actually forged a living out of promoting meat is just complete and utter nonsense.
21:51
Um, my message has always been real food and they haven't done their research because my diet books were written while I was a vegetarian.
23:13
Yeah.
6:42
So my little three-minute soliloquy, any truth into what I was saying or where are we on all of this?
6:50
Well, do you know, that's really interesting 'cause I hadn't made that connection.
6:54
Um, so I, I did actually look at the rice diet a few years ago, but I tweeted about it recently 'cause it just comes up every now and again.
7:02
And people say, "Oh, you know, there's this diet where it was between 94 to 96% carbohydrate, 1 to 2% fat, and just a couple of percent protein filling in those gaps." And the reason there was any flexibility, there was this sort of 2,000 calorie a day basic diet, which as you said, was rice, fruit, but particularly fruit juice, which is even worse than just fruit.
7:25
But then you were allowed sucrose, yeah, table sugar ad lib.
7:30
And they were averaging about 100 grams a day of table sugar, but you could be having, um, well, easily with that, that would be about 400 calories.
7:37
They were having maybe 500 calories in some cases of just pure sugar, which is when you got the carbohydrate up to about 96%.

Mm-hmm.
15:08
What, what are your thoughts there?
15:10
That is a really interesting one because the people who quite often end up with a weight problem, and I do explore this in that book, Why Do We Overeat?, our sort of history with food, you know, we fall over as a child, we cry, we get given something sweet.
15:24
We have Easter, it's something sweet.
15:26
We get an egg.
15:26
Christmas, we get chocolate.
15:28
Halloween, we get chocolate.
15:29
The fake food industry very, very deliberately tries to associate nice treats as they want us to see it.

So what does that look like, and what's a healthy, sustainable approach to, to losing weight without having to use weight loss jabs?
44:56
Has
44:56
it? No, it totally hasn't.
44:58
Right.
44:58
So let's just cover that off.
45:00
So we need to do a carbohydrate 101.
45:02
Okay.
45:03
So carbohydrate 101, we start off with monosaccharides, single sugars, and those are glucose, fructose and galactose.

And then number two, and what I want to spend the remainder of this hour on is how do we change that as an individual, as a small group, as a larger group? How do we get this information in front of people? How do we change the guidelines? How do we change things at the county level, the state level, and the federal level? How do we erase this foolishness that saturated fat's bad for you and fiber's good for you? How do we get this out of the public zeitgeist? How do we change that?
7:42
Let's go back in history and talk about where that started and how we got to current day.
7:48
great um i did a post on this actually over the summer so it was it was called the origin of of our beliefs on fat and they are beliefs they're not facts they're not evidence-based so i traced it back to the the main person who features in this whole story is a american doctor called ansel keys a lot of people in this field will have heard of him And he'd actually spent, I mean, he'd done a brilliant experiment.
8:13
So he'd done the Minnesota starvation experiment, which was published in 1950.
8:19
And he was studying people who didn't want to go to war, basically conscientious objectors.
8:24
And he was studying the impact of caloric deficit, because that's what we thought was going to happen if America joined in the war.
8:31
And then you guys would start having rationing like we were going to have.
8:34
So he was a prominent researcher.
