vanishing caloric density: energy dense foods that meltdown rapidly in the mouth, often lack satiety (Dr. Drewnowski)

the problem with sugared soft drinks: energy consumed as fluid calories are not counted by the body as contributing to satiety, in the same way that energy consumed in solids.

Putting these two data points together, It would therefore seem that non-solid foods don’t satiate.

It makes sense that industry includes these forms of food in our diet, as the less satiety we experience, the more food we eat.

This also explains why fruit juice, but not solid fruit, leads to weight gain. It’s nothing to do with fibre slowing the absorption of calories in the gut, it’s to do with the satiating effects of calories derived from solids vs liquids.

This thesis makes sense in evolutionary terms, as the only pre-agricultural sources of liquid calories would have been honey – water being the mainstay.
