Discussion: Take, for example, two identical twins. Will they necessarily get the same amount of calories from the same calories but with different compositions?

The answer is no! People with diabetes often suffer from obesity and are unaware that not all calories are the same! The calories from industrialized food are not the same as those from natural food; they cause faster weight gain. The nutrients we eat and drink and the calories they carry cannot vanish, but they can be redirected to other non-energy, "non-countable" purposes.

Surprisingly, processed foods make us gain weight much faster than the same calories in natural foods. The amount of energy in food and beverages available for the body's use is not fixed and is not uniform for everyone! The "calorie is a calorie" tautology is wrong.
