Yes, Magnesium does help you lose weight, but the key here is to simultaneously, burn more calories than you eat to lose weight but also, take a Magnesium Supplement at the same time.

Magnesium is one of the most abundant minerals in your body and about half of it is found in your bones, while the other half  lies in your organs and cells.

Magnesium is essential for your health.

Your entire body needs magnesium, from your teeth and bones, to your heart and kidneys. Magnesium helps your body produce energy, activate enzymes and helps maintain levels of other essential nutrients such as zinc, vitaminD and potassium throughout your body.
The University of Maryland Medical Centre reports that magnesium is essential for proper heart rhythm. A deficiency in magnesium can lead to arrhythmia and eventually congestive heart failure.

Magnesium and Weight Loss

Magnesium does not directly enhance weight and fat loss, but it may help in some way. According to research published in the February 2009 edition of the Journal of Pharmaceutical and Biomedical Analysis, increased intake of magnesium can promote enhanced levels of free testosterone in your body. Testosterone can reduce your levels of body fat and can increase your lean muscle mass. Muscle burns more calories than fat, so this can be beneficial for weight loss.

Examples of Magnesium found in foods.

You can find magnesium in many foods, particularly green vegetables. As the National Institute of Health explain, the chlorophyll which gives green vegetables their color contains magnesium, so examples would be spinach and soybeans high in magnesium. In addition, nuts, cashews, almonds, walnuts, oatmeal, potatoes, beans, lentils and halibut are also rich in magnesium.

Consuming magnesium alone will not be enough to lose weight. You need to be burning more calories than what you are eating to shed pounds. Therefore, if you choose magnesium-rich-foods that are low in calories such as, spinach, halibut and different kinds of peppers, this will be very helpful to lose weight. Also, halibut and yogurt are rich in protein, a nutrient that can facilitate weight loss because it promotes an increase in your daily calorie burning.
