    Suppose a person loses ten kilograms due to dieting and/or exercise.

    How much is lost via respiration ? How much via other mechanisms ?

    It is my guess that respiration & urination are the major (perhaps the only) mechanisms for weight loss.

    It is really strange for me but i don't think so that it is impossible in this fast and scientific era.
    This time is full of the facilities each and every thing is possible in this life and condition.

    It is impossible. You need to accelerate your metabolism. Metabolism can be accelerated through making sport, at least for 30 minutes at 120 heatbeats per minute to 140 bpm (if you are young).

    The other way is with an hypocaloric diet. I prefer this way, and practice sport for plaesure

    You could lost more than 1 litre of water just by respiration/perspiration. If water is heavy then this imply a large weight loss: of course, a large bottle of water is quite heavy.

    A pint's a pound the world around.
    Seriously, though, I think it's a good question. Of course, to lose weight you have to burn more calories than you eat, but how does the weight actually leave your body. I guess a lot of it is in the form of carbon dioxide exhaled, but I don't know what else there is.

    If you are drinking enough water to maintain yourself in comfort then respiration and urination will cause no net weight lose. If you are forcing yourself into dehydration you will weigh less but you are in a state of metabolic distress and as soon as you drink enough to not feel thirsty, your weght is back. Net weight loss is from taking in less calories than you burn through metabolic processes. One way to do this to severely restrict intake, another is to restrict intake and increase exercise. Increased exercise without restricting intake will actually cause increased weight through increased muscle mass.

    respiration is nearly de only way to loss weight
    1mol of glucose (180g) needs 6 mols of O2 (192g) to produce 6 mols of CO2 (264g) + 6 mols of H2O (108g)

    Glucose + O2 = CO2 + H2O
    180 + 192 = 264 + 108
    (Input 180+192=372 Ouput 264+108= 372)
    then the weight of CO2 (264g) that is eliminated by lungs is greater than the H20 (108g) and this is so manly excreted by lungs.

    (glucose=6C*12+12H*1+6O*16 =180)
    (32X6=192)
    (O2=16X2=32)
    Atomic weights
    O=16 C=14 H=1
    Glucose=6C*12+12H*1+6O*16 =180
    O2=16X2=32
    H2O=2+16=18
    CO2=12+16*2=44

    I drop a couple of pounds every morning on my seven mile run, most diets include stuff that causes to lose water weight in the first week so that is why we stick with the diet to see fast results, but rapid weight loss is usually just rapid water loss. A long term sensible diet can live with forever and a sensible exercise program are the way to go to lose weight and get healthy.
