Our bodies require magnesium for more than 300 chemical reactions, including keeping heart rhythm steady and regulating blood sugar levels, but in addition to its health benefits, this nutrient may also aid in weight loss and body shaping. A 2013 study in the Journal of Nutrition found that higher magnesium intake was associated with lower levels of fasting glucose and insulin (markers related to fat and weight gain), and one study from England found that a magnesium supplement may have some beneficial effects on reducing fluid retention during the menstrual cycle, meaning you'll feel less bloated.
Flat-belly solution: Eat more magnesium-rich foods, such as leafy green vegetables, beans, and nuts. Or talk to your doctor about taking a supplement. The recommended amount of magnesium for women under 30 is 310mg, and 320mg for women 30 and over.
