I have the honor of working with the group of people

subject to the last widely accepted prejudice: being fat.

These people have suffered a lot by the time they see me:

shame, guilt, blame and outright discrimination.

The attitude that many take, including those in healthcare,

is that these people are to blame for their situation.

If they could just control themselves, they wouldn't be overweight,

Please let me tell you this is not the case.

The blame, if we've got to extend some here,

Obesity is a disease, it's not something created by lack of character.

It's a hormonal disease, and there are many hormones involved.

And one of the main ones is a hormone called insulin.

Most obese individuals are resistant to this hormone, insulin.

So, what does that mean exactly, to be resistant to insulin?

Well, insulin resistance is essentially a state of pre-pre-type 2 diabetes.

Insulin's job is to drive glucose, or blood sugar,

In a nutshell, when someone is insulin resistant,

they are having trouble getting blood sugar where it needs to go,

And it just can't hang out in the blood after we eat

or we would all have a diabetic crisis after every meal!

So, when someone is resistant to insulin,

the body's response to this is to just make more of it.

and for a while, years even, this is going to keep up,

and blood sugar levels can remain normal.

However, usually it can't keep up forever,

and even those elevated levels of insulin

are not enough to keep blood sugar in the normal range.

that most of my patients have insulin resistance or diabetes.

And if you are sitting there thinking, "Phew, that's not me,"

because almost 50% of adult Americans now have diabetes or prediabetes.

But that's hardly everyone who has issues with insulin.

people have elevated insulin levels due to insulin resistance

before the diagnosis of even prediabetes is made.

Plus it's been shown that 16-25% of normal-weight adults

So, in case you're keeping track, this is a heck of a lot of us.

So, the trouble with insulin resistance is:

If it goes up, we are at great risk for developing type 2 diabetes.

and the food we eat much more likely to be stored as fat.

So we can start to see how it's going to be a problem

for diseases like obesity and metabolic issues like diabetes.

But what if we traced this problem back to the beginning,

and we just didn't have so much glucose around

is either a carbohydrate, a protein or a fat,

and they all have very different effect on glucose and therefore insulin levels,

our insulin and glucose are going to spike up fast.

But take a look at what happens when we eat fat.

And, this is going to wind up being very important.

So, now I want to translate that graph for you

and think about the last time you ate an American version of Chinese food.

We all know there's rules associated with this, right?

And the first rule is: You're going to overeat.

until you are literally busting at the seams.

Rule number two is: In an hour you're starving.

Well, because the rice in that meal caused glucose and insulin to skyrocket,

which triggered hunger, fat storage and cravings.

So, if you are insulin resistant to begin with,

and your insulin levels are already higher,

Eat carbs, your glucose goes up, your insulin goes up,

So, how do we recommend to these people to eat,

because it seems like that would be really important, and it is.

because the general recommendations are to tell patients with type 2 diabetes

to consume 40 to 65 grams of carbohydrates per meal,

And remember what's going to happen to glucose and insulin,
