Let's talk more about why protein is so important for maintaining a healthy body composition.

It turns out from insects to non-human primates to humans. When we decrease our protein intake,

we tend to increase our calorie consumption from carbohydrates and fats, which can lead to obesity

over time and weight gain over time. We're going to hone in on this theory, this hypothesis known

as the protein leverage hypothesis. And this has been circulating in academic circles for

quite some time. I think it's important that you understand the nutritional geometry that

has been sussed out again in insects, in non-human primates, going down animals, spider monkeys,

black howler monkeys, orangutans and chimpanzees. In all sorts of insects, animals as well as

humans, if we decrease our protein intake, we tend to increase calorie consumption from carbohydrates

and fats, which over time leads to fat gain. So let's look at figure one here. This really helps

convey the story of this jargonistic nomenclature known as a protein leverage hypothesis. When protein

is insufficient, there is energy excess in the form of carbohydrates and fats. And that can lead

to weight gain over time. So here's what the scientists say. A core contribution of nutritional

ecology to obesity research is the phenomenon of protein leverage, in which the strong human

appetite for protein drives increased intake of energy when dietary protein is diluted, i.e.

in low protein diets. Now, the scientists want to say a hallmark of physiological regulation is

that the intake of protein is both regulated and its regulation is prioritized over, that is

stronger than regulation of other dietary components, like carbohydrates and fats,

then excess energy intake will result when protein becomes diluted in the food supply by fats

and carbohydrates. And what have we seen over the past 60 years? People are eating less and less

protein and having more hyper-palatable process carbohydrates and fats. And so these are low

protein foods. If you think about all of the junk food, whether it's ice cream cookies, crackers,
