All the organs of your body recieve signals from the brain, as to how they are supposed to function. Those signals are carried through nerves in the spinal bones. If those bones are out of alignment for any reason, they may pinch or put pressure on nerves, interrupting with the signals from the brain. This creates imbalances in the way your organs function, any organ or gland that is not funtioning at 100% capacity could be influencing your weight.
Poorly operating glands can influence hormone levels that affect everything from food cravings to moods. If signals to the lungs are interupted you aren't getting the full oxygen your body needs for proper function, let alone optimal funtioning metabolism.
