Can anyone explain health readings please

I have the BC-1000 and here's what I understand these to be as well as below is their statements:

OK so I'll start with my general observations, the scale is extremely accurate from measurement to measurement as well as from one BC-1000 to another (I have 2 I use) That means the scale is very precise. the BIG HOWEVER, is that it can vary dramatically from day 2 day, it seems to me body water has the biggest effect on scale and throws off the muscle & fat figures tremendously. i.e. weight yourself, do heavy exercise for 1 hour, then weigh again, because of sweat water loss it will say you lost 3lbs of muscle (impossible) and gained 2 lbs of fat (impossible). So, pick a time of day and keep consistent with your measurements for more accurate trending of results. I scale in every morning before my shower and before any intake of food & water. I also empty my bladder but that's it. because a BM can also change the numbers a bit.

Visceral Fat is the fat around your midsection, the gut fat as opposed to the fat spread throughout the body & muscles.

Bone density shouldn't vary at all, I've been taking measurements for 3 months and it's been 7.6lbs with the exception of 1 time it came in at 7.4... so that seems strange. I don't think it actually measures it, it's more of a calculation based on weight, height, and the other stats... i.e. if it knows your frame, and muscle/fat & water mass, than everything left over must be bone.

Metabolic age is based on how healthy you are. So if you are really in your 30's, if you are 40lbs overweight it probably will calculate you as in the 50's due to shortened life span as well as your body having to do significantly more more each day... If you get down to healthy weight levels you age drops into the teens!

I'm not to keen on the caloric intake - it's a direct calc doubling the basil metabolic rate - maybe that's a 1-day max spike in calories you could take, mine is always like 4200 range... that would plump me up if I ate that much daily.

Here's what Tanita says each is:
