Same for me with eliminating carbs; combining keto + IF is pretty effective and I've lost about half of the weight from ATH to where I want to be through it. IF is nice because it provides an "all or nothing, but not forever" restriction, and keto is a reasonable framework for food selectivity. Keeping enough protein for not losing muscle and overall ideal; I wish I'd done this when I was 16 and not when I was in my 40s.
