Anyone know anything about gene or genetics testing? I'd ideally like to find out if there's anything I need to be worried about passing on to my children and also find out if I have a genetic disorder of obesity of some kind as almost no amount of diet and exercise results in weight loss for me (I start gaining weight rapidly every time I try a "diet" like slimfast or weight watchers as they all contain vastly more calories than I usually eat). Nothing wrong with my thyroid before anyone asks.
Has anyone had this done and is one test as good as another? Is one provider as good as another? Do I need to get multiple tests or just one?
