Every Diet Works. But Are You Still On a Diet?
Which diets work best.
Anton Titov, MD: Let's talk about diets.
Any kind of diets.
Robert Lustig: Any kind of diets! Dr.
Anton Titov: Is there any diet that works? If not, why not? What's the problem? Dr.
Robert Lustig, MD (Pediatric neuroendocrinologist, UCSF): Every diet works, for two months.
And then it doesn't work.
My colleague, Doctor Christopher Gardner at Stanford University did a very famous study.
It was called the "A to Z study".
What he saw was it didn't matter, he tested four different diets against each other.
And every diet works for the first two months.
Then it didn't work.
And the reason was because nobody was on the diet anymore.
They thought they were but they were not.
Different food stuffs had seeped back into their diet, and actually destroyed their diet.
And that makes perfect sense based on what we know, number one, about addiction, number two, what we know about humans and variety, and number three, what we know about the biochemistry of leptin.
So no diet make sense.
What makes sense is a lifestyle change.
Now what is that lifestyle change look like? Let's look at all the diets that purportedly work: Atkins, Mediterranean diet, Zone diet, Sugar Busters diet, Traditional Japanese diet, Paleo diet, Vegan diet.
Diets all over the place, with different dietary compositions, everyone one of them.
They are as far opposite each other as you could possibly imagine.
Except they are not.
In fact, they are all the same.
Because every one of those diets I just mentioned, and all of them have been shown to work, they all have two things low sugar, high fiber.
Titov: Low sugar, high-fiber? Dr.
Lustig: And what is a low sugar high fiber diet called? Real food! That's what real food has.
Titov: What helps in the long term is eating real food.
Robert Lustig, MD: Right.
The question is what is real food? In fact, a lot of people don't know what real food is.
A lot of people think salad dressing is real food.
A lot of people think yogurt is real food.
This is the problem.
The food industry has done such a good job of indoctrinating us.
They brainwashed us, or whatever it is that they did to us over the last 35 years.
People have forgotten how to cook.
I will tell you right now, if you don't know how to cook – you are hostage to the food industry for the rest of your life.
We need to re-teach people how to eat.
And that means teaching people how to cook.
This is probably the single best thing that government could do to solve the obesity and diabetes epidemics that are going on right now.
Government could help people get away from processed food.
The problem is, it costs money.
And no one is willing to do it.
