Maybe a little worried, but not extremely because you can change your eating habits and make them healthier.Eating lots of junk food might not make you fat, but it can cause major problems inside your body that will affect your life ... so it s in your best interest to find healthy things that don t make you sick and to eat those instead. If you re not ready for vegetables, start with fruits - healthy but taste a lot better!Water is also really important to keep your organs healthy (one of the problems caused by not enough water is kidney problems). Tap water tastes bad but there are certain brands of water that have all the chemicals and minerals filtered out ... try those, water is the best possible thing to drink and can actually help with weight loss because it cleans out your body.
if your losing weight rapidly, i think it may be something to ask your doctor about, that could be a sign of something serious. but 140pds is average, thats about what i weigh. if you are concerned or you feel sick, or unhealthy it wouldnt hurt to ask your doctor; the worst thing that could happen is they say your healthy. but hey, thats just my opinion.hope it helps :D
You should be concerned... Just beicause your weight is average doesnt mean your body is healthy. You could be consuming all of that food and just staying thin because your not healthy.Try to eat better, drink Gatorade or juices.
bad health eat a salad
