Reducing Calorie Intake is only the first half of CICO. Not everyone can even absorb the same amount of calories from the same piece of food, because calories are about burning stuff not about human digestion and metabolism.
Yes there’s variation between humans but the principal is true. If you absorb less than you use you will lose weight. You might have to adjust your intake for your own body chemistry but that’s how it works.
