Again, since it's very clear that this is important,

Why ignore it, right?

That boggles my mind.

And this is where this sort of obsession with calories, it sort of boggles my mind sometimes because it's like, you know, all these people are out there and they're sort of just denying all this stuff about calories.

It doesn't matter.

It all comes back to calories in, calories out.

It's like, they're almost like bullies.

It's like these calorie bullies are like, oh, it doesn't matter.

It doesn't matter.

It's just calories.

It's just calories.

Like, you know, you've studied human biology for like years and we've detailed maps of what happens, what hormones are released when you eat these foods and those foods.

Why would you think that's completely irrelevant, right?

It doesn't even make any sense.

Then what happens?

So that's your calories in.

But because you've pushed the body fat up, right, your body fat thermostat up, the way, so say you eat 2,000 calories, you burn 2,000 calories, your weight is stable, right?

So now you give insulin and now you want to eat 2,500 calories, right?

So that you gain weight, right?

2,500 calories in, 2,000 calories out, you're going to gain weight.
