For some people "starving" themselves is easier. It requires less decision making and therefore less decision fatigue. Intermittent fasting is a perfect balance of physical discomfort and mental effort for me.

I feel no physical discomfort when doing the standard 16/8 schedule these days and only feel slight discomfort on a 22/2 schedule. I'd much rather do this than have to meal plan and have anxiety over what restaurant my friends chose for the night.

But I also understand that it's not for everyone and wouldn't push judgement on anyone who chooses some alternative method of controlling weight/insulin sensitivity
