Measuring human digestive efficiency vs. a flame

From Applied Science.

"200 Calories" on a nutrition label doesn’t describe the total flammable caloric content. I explore the differences between digestible and flammable calories using a homemade calorimeter with glass windows.

Hmm, I perhaps mis-remembered that 20% stat from Sally Le Page’s video: https://www.youtube.com/watch?v=92F_yocEchA There may have been another source that indicated the 20% number. This will probably show up in my future video on macronutrients.
