For example, like it's breakfast time, you eat.

It's lunch time, you eat.

It's snack time, you eat.

You go to a sporting event, you eat.

But it's not the physical hunger, it's the conditioned hunger that's causing this food noise.

that this idea that like a calorie is a calorie, so therefore all calories are equally fattening, but it's actually not true in any way.

When you eat different foods, they may have the same number of calories, but they produce different hormones in your body.

Your body responds to cookies, for example, with certain hormones and it responds to say eggs with different hormones.

And therefore the effect is totally different because for every calorie that you eat,

your body could store it or it could burn it.

And which one it does is very important because of course one of them you're gonna have lots of energy, you're gonna feel great, the other one you're just gonna get fat.

So those hormonal responses are very important.

So beyond the number of calories, it's also the types of food that you eat, the processing and so on.

But the other thing that people haven't focused on a lot is sort of the underlying reasons why people eat.

And if you think about it,

it's really about the hunger because we eat when we're hungry and we stop eating when we're full.

Therefore, the sort of driving force behind most eating behavior is hunger.

So we need to understand the different types of hunger, what drives it, what you can do about it.

Because really, if we didn't have hunger, none of us would have trouble losing weight, right?

And that's the lesson that a lot of these new weight loss drugs have.
