The bloating might be (probably is) the "starvation" phase (the stomach bloats when their is little to eat). You probably also have undigested food in you (common, not to worry, probably is the most common cause of being overweight in this country). For you, the bloating is temporary and will clear up when you start eating. Digestion and elimination of what is eaten is very important to overall health, but if your intestine is clogged with undigested food, you will not only be bloated because digestion is not working well, you might even feel back pain because of pressure on your backbone. You also will not be absorbing very well the nutrients that you eat or drink. Most likely, you will need PROBIOTICS to help your digestion. Yogurt or Kefir usually have the cultures that are helpful to your digestive system. Fructo-oligo-saccharrides (F.O.S.) is also good (ask at the health food store or look on that website). Of course, enough WATER everyday ( .5 ounces for every pound of body weight) and even walking around the block will stimulate the digestion. Don't forget fiber (extra water for the fiber is necessary or you'll start gagging). Read about "transit time" at that website.
