Eat less. Move more. Lose weight.
If the amount you move doesn’t change, eating less still will make you lose weight.
It’s just physics at the end of the day, regardless of how unhappy you are with units of measurement.
As I have explained the Move More part doesn’t actually do much long term. So that’s my problem with it. Fairly easy to understand. Again calories aren’t even a good measurement to begin with, you aren’t an engine or a fire. More like a fuel cell.
Cico is a ratio of two things. If you isolate one half and claim it doesn’t work, you’re no longer critiquing the method, your critiquing a thing you don’t like and using that to claim the ratio doesn’t work.
