I'll be the first to always say that IIFYM, in my personal experience, is bullshit. Had way too many times prepping where I've been able to add calories in order to decrease weight among other things I've seen with myself.
However, I've been noticing that different food sources, specifically carbs, change the way I look and lose fat given the total macronutrients quantities and ratios are still the same. For example, I've done periods of experimentation where I'll use oats or rice or potatoes as sole carb sources for a period of time and, obviously other factors come into play, but I've seen enough consistency between food sources to make it qualitatively apparent to me.
This is obviously a qualitative comparison as well as anecdote but was curious if anyone else had had similar personal experiences.
