Since you didn't include the options, a combination eating less and exercising more generally results in weight loss.
Coordination problems since walking with the hip or doing alot of movement. It would have cause an injury to your hip.
Having body fat contributes to having a menstrual cycle. If a woman loses too much body fat, she can stop having her menstrual cycle because you need a certain amount for it to be able to function as normal. I don't think the body would benefit from ceasing to menstruate, because at that point it isn't really healthy. However, usually if a woman gains back some of the body fat or starts eating fattier foots/exercising less, her period will start again.
