What are the bad effects of obesity? How it can be cured without medicines.?

I am intrested to know the common reasons of obesity and possible solution with out medicines

eating too much than the required amount of dietary intake, lack of exercise is basically the reason for obesity.
Obesity may trigger diseases like heart attack, high blood pressure, diabetes and a lot more.
If you don't want to take any medicine to reduce your weight, I suggest that you cut off your intake of food little by little each week, for example if you eat 4 cups of rice every meal take off 1/2 cup each week.
If your obese it would be difficult for you to exercise. Walking would be best for you. Walk at least 500 meter every morning.

Always remember to observe your diet and walk.......

Obesity can cause lots of problem like blood pressure , cholestrol , immobility , and many diseases due to the fact that it will be difficult for blood to reach all parts of the body efficiently . I read this somewhere though I am not an expert . I think you should start taking a good diet and also maybe try YOGA .
