Burning fat and sugars is essentially the same as what happens when you burn wood, or when you car burns its fuel. Where does the wood go as it burns? Gasses, mainly CO2 (though there is some residue left in the form of ashes; much much less than the initial amount of wood). Where does the fuel from your fuel tank go when you drive? Again, gasses out of the exhaust, except for a small amount of soot and other small particulate matter.
Weight loss is burning the fat reserves in the body, very similar to burning wood or fuel (but in a more controlled manner; there are no flames). The CO2 leaves your boy through mouth and nose by breathing. Burning sugars is good too: burning it before it gets converted to fat prevents it from contributing to the fat reserves.
Pooping makes no difference: poop is simply the non-digestible portion of your food that. It will make its way out of your body, but never contributes to fat and sugar reserves in the body.
Neither does sweating, by itself: you loose water, which needs to be replenished (it will result in short term lower weight, until the water is replenished; doesn't help against overweight, but is used in boxing and judo etc. to get in as low a weight class as possible). Again, doesn't affect fat and sugar. But when sweating is the result of physical activity, that physical activity does help loose weight.
When doing physical exercise, you'll notice you have to breath deeper and/or faster. That's to provide more O2 to your body, and to release the CO2 that is produced. Even during rest the body continually burns some fat and/or sugar, with the produced CO2 being expelled the same way. So yes, you lose weight by breathing it out. But that breathing out more CO2 has to be triggered by a higher metabolism, such as can be achieved through physical exercise.
