Or I tell people, if you ever want to be disappointed, weigh out a serving of peanut butter if you want to be depressed.

Um, or they do track accurately or sorry, or they see what they're consuming and they change their behavior already because they're tracking because they're monitoring.

Right.

And I mean, it's, if you look at studies, it's very consistent.

Uh, people under report their calorie intake by 30 to 50%.

Um, yeah, there's a very classic study in 1992, uh, new England journal of medicine, uh,

They had people who self-reportedly were weight loss resistant.

So these people claimed that they were eating 1,200 calories a day.

They specifically wanted this population.

And these were obese people.

And they said they put them in metabolic ward.

So they're tracking their energy expenditure in a metabolic chamber.

And they know exactly what they're eating.

And they even told them, like, we'll know if you're eating more than you say.

And they also looked at lean mass, BMR.

Total energy expenditure.

So what was really interesting, this was one of the first studies that showed that obese people didn't have slow metabolisms.

And like at first, the first few decades of us trying to deal with the obesity crisis was us like looking on the metabolism side.

How do – they must have slow metabolisms or we've got to increase metabolic rate.

And now we know it's the appetite side that has a much stronger effect on body weight regulation.
