Like the others have said, it's more about calories.
Get enough protein, EFAs and it doesn't really matter unless there are underlying issues like insulin resistance or even diabetes, thyroid out of whack etc. Then some tweaking one direction or another needs to be done.
It really should be the calorie continuum. Eat over maintenance and you'll add weight/fat. Eat at maintenance and you'll stay the same weight/fat (assuming variables are in check). Eat below maintenance and you'll lose weight/fat.
Of course, glycogen depletion can help to increase fatty acid oxidation, but it's not really that important unless you're into extreme approaches (NHE, AD, UD2.0, Body Opus etc.).
And if you don't think kettleball squat cleans are difficult, I say, step up to the med-ball
