I must say that water retention is an issue I've found frustrating to nail down. I get it periodically and the facial bloating makes a night-and-day difference in my appearance as well as adding several scale pounds. It doesn't ever seem to be as simple as 'too much salt' or 'eating too many carbs'--there are certain foods I suspect strongly including dairy, eggs, cashews, and dry-roasted almonds (all favorites, unfortunately). Dosages are important as well. Is it PUFA-derived inflammation? A specific allergy/sensitivity? I dunno. Vigorous exercise seems to trigger it occasionally too--always annoying, because you'd expect to look more lean & honed after a big workout, not puffy.
The renal & adrenal endocrine machinery controlling this fluid balance (prostaglandins, aldosterone...) seems too intricate for me to understand, let alone control--so I just try to stick with the foods that work for me, take note of the offenders, and be willing to pay the price for lapses.
