Is weight lost by...

[APO]

Sweat? or Movement? Because Its pretty hot where I live right now and I break a ton of sweat when I ddr.

All of the above, and then some. Sorry about being so vague.

Sweating will cause you to lose water weight, but that's not "real" weight loss. I'm assuming you're talking in regards to exercise. Movement is the key. You need to get your heart rate up. (go back and re-read the Health mode on the main site www.getupmove.com/health.html). Getting your heart rate up does a few things:
1. It raises your metabolism, which causes your body to burn more calories
2. It improves blood flow throughout the body, allowing for more oxygen and nutrients to reach your muscles. This in turn allows the muscles to work more efficiently, burning more calories.
3. It helps build muscle. Each pound of muscle will burn 50 calories per day just existing.

Sweating is merely your body exuding water to cool your body down. It burns little to no calories. It is, however, a good way to determine if your body is warmed up enough to do more strenuous exercise. If you aren't sweating, your muscles may still be cold and tight, and you'll run a larger risk of pulling or tearing something.

The real answer to your question is that weight is lost by your body burning more calories than it takes in. The energy deficiency is corrected by tapping into your body's stored energy reserves (fat).

Is there any way to check your muscle mass? I have a machine that tells me how fat i am (fat%)(BMI%) is there anyway i can utilize this tool in my benefit? thanks

Yes, sort of. Let's work an example:

Let say I'm 180lbs with 33% body fat.

180 * .33 = 60 lbs of fat.
180lbs total body weight - 60 lbs fat = 120 lbs lean body mass (LBM).

Unfortunately there's no easy way to separate out bones and organs from your LBM to get a true muscle mass weight. Fortunately, most systems base their measurements off of LBM, not muscle mass (like how much protein you should consume to ensure your body has enough to build muscle).

well i'm 159 with a fat % of 18.

so that means I have 28.6 pounds of fat?! gawd damn.. and I thought i was doing goo too.

well it beats my 186*.31=59 pounds

I guess time isnt with me but I'm going in the right direction just like most of us here in the fourms. No ones been on lately though... maybe there all done there wieght loss? I'm lonely

18% body fat is really quite good. Most athletes range between 9 and 15% body fat. Under about 6-7% you start to look grotesque, like some bodybuilders.
