Losing weight is not about CICO. Of course you need more calories out than in. Saying that is like saying “To climb a mointain, make sure every day you ascend more meters than you descend”. How useful is that piece of wisdom? The rule of thumb is that for each 1 kilometer of additional elevation, you need to ascend 1000 more meters than you descend.

huh? I think you contradicted yourself. Losing weight absolutely is about CICO. You can't consistently eat more calories than you burn and lose weight.

I’m saying CICO is a truism. Telling someone losing weight is about CICO is as valuable as telling someone that mountain climbing is about taking more steps up than down.

Imagine someone sharing their experience with some new climbing gear, and someone else chiming in “All this gear talk is irrelevant, just make sure you take more steps up than down”. What value does such a comment bring?

The OP was sharing with us his experience with fasting. The response was pretty much “your fasting was not relevant. Just the fact that you burned more calories than you consumed.”

What? Your first two sentences contradict each-other and then your analogy makes no sense
