ways of losing weight

Summer arrived, the flesh of our body can not be covered by the heavy clothes, so, in the summer most of the girls will reduce weight to achieve a slim figure, so what kind of weight loss method is the best? I think there is no best, only to do for their own. As far as I am concerned, I usually have more meat on my stomach, so I will choose hula hoop. However, hula hoop can't be turned for a long time, because it will have a bad effect on my body. Do you have other better ways to lose weight? Share it with me! thank you
