Physics dominates, but it’s often too simple a model to be useful in diet planning. When you run things through the filter of the an incomprehensible machine like the Human brain and metabolic and hormonal pathways the system gets much more complicated and useful. The non-caloric fibre content of food is vital to gut flora, whose importance we’re still discovering. Different foods affect hunger differently. High fat foods are more satiating that sugar. The body isn’t a bucket, it’s a donut which has the capacity to absorb some food through internal walls while the food slips through very slowly. If you drink a bottle of oil, you won’t get fat. You’ll just have very runny and uncomfortable stool for a while.
