why are there still so many people overweight despite the current fitness craze ?   well , there are certain factors that effect people's size and weight .   what are they ?   one study said that low-income groups have a higher percentage of over-weight people than higher income families .   why ?   the survey said that the low , income groups eat more junk food on a daily basis .   that makes sense . Probably less time to make dinner and the junk food is cheaper .   and junk food contains lots of fat and oil . There is one final reason why so many people are fat .   what's that ?   nobody exercises anymore-not even kids ! The average american home has the TV on for 6 hours a day !   wow ! No wonder people are so fat . Say , Carl , looks like you could be doing a bit more exercising .   yeah , I guess so .   you should consider eating healthier food and getting some more exercise .   hey , I started a diet and lost 10 pounds .
