Depends on what you actually mean by CICO
No one denies that eating less food is going to make you skinnier, the problem is that when people talk about CICO 99/100 times they mean "eat the same shit you're eating now, but less", which is a recipe for disaster. Just saying "eat less" is completely ignoring human biology and hormones.
If it isn't obvious enough, your body works differently when you're eating 1600 calories of ground beef and turkey as opposed to 1600 calories of cereal, oats, and pizza. With a healthy diet your body will self select for lower intake and you'll easily lose weight without counting calories.
