Does eating foods high in magnesium help you lose weight? Some people say it does. I read the studies and have an answer below. First, a quick primer on magnesium and the amazing health benefits.
Magnesium is essential for the health of your bones, muscles, heart, brain and nervous system.
Often referred to as the master commander in your body, this electrolyte produces antioxidants to keep you healthy.
Magnesium is in charge of hundreds of biochemical reactions in your body. These reactions help turn food into energy, make your muscles move, form protein and maintain your nervous system.
Much like potassium, most of us fail to get enough magnesium in our diets. Some research suggests that two thirds of us may be deficient.
Magnesium deficiency is incredibly dangerous. After your bones, most of the magnesium in your body is found in your heart and brain (1).
For this reason, magnesium deficiency can lead to diabetes, heart disease, bone-related issues and Alzheimer’s (2).
Thankfully, there are many delicious whole foods that are full of magnesium. You can find magnesium in foods like dark leafy vegetables, fish, seeds and more. Scroll down for the full list.
First I’ll touch on why magnesium is so important to your health, performance and longevity.
Magnesium Health Benefits
Better Sleep Quality With Magnesium
Eating more magnesium-rich foods may be beneficial to a good night’s sleep. Those who are into magnesium swear by its ability to relax your mind and muscles to prepare you for sleep.
The research is early on magnesium and sleep, there’s one interesting study which shows magnesium to increase sleep quality and decrease time to sleep in those with insomnia (3).
Magnesium Can Boost Exercise Performance
Magnesium increases exercise performance by helping your body produce energy. It’s been shown that our body needs 10-20% more magnesium during exercise than when at rest (4).
As a key electrolyte, magnesium also shuttles blood sugar into your working muscles and helps your body ward off fatigue by disposing of lactate (5).
Research shows magnesium to boost exercise performance in everyone from athletes, to elderly populations with chronic disease (6).
One study showed faster running, cycling and swimming times in those who supplemented with magnesium. These participants also had lower insulin and stress hormone levels (7).
Magnesium Normalizes Blood Sugar And Protects Against Diabetes
Magnesium helps to stabilize blood sugar in those with type 2 diabetes. Let me explain because this is pretty convincing.
At the heart of diabetes is insulin resistance: an inability of your liver and muscles to properly absorb sugar from your bloodstream. It is the leading cause of metabolic syndrome and type 2 diabetes.
Those with type 2 diabetes typically have less magnesium in their blood. Researchers think that magnesium helps to keep our bodies blood sugar levels in balance (8).
Magnesium Can Reduce High Blood Pressure To Support Your Heart
If you have high blood pressure, your heart has to work harder, putting a strain on your heart muscles leading to heart disease.
Magnesium deficiency is linked to cardiovascular (heart) disease (11).
Eating foods high in magnesium can have a protective effect on high blood pressure and heart disease. Studies show the magnesium can reduce high blood pressure (12).
Magnesium Alleviates PMS Symptoms
Premenstrual syndrome (PMS) is common among women of childbearing age. Symptoms vary but can include water retention, abdominal cramps, digestive issues, tiredness, mood swings and more.
Interestingly, magnesium improves mood, reduces water retention and other symptoms in women suffering from PMS (13).
Magnesium Support Bone Health
Most of us associate calcium with strong bones, when in fact, magnesium plays a crucial role.
Low levels of magnesium results in more fragile bones and higher risk for osteoporosis (14). With less magnesium, there is more inflammation and less crystal formation in your bones. Eventually, your bones gradually degrade and break down.
Lastly, those with higher magnesium levels are shown to have higher bone mineral density (15).
Magnesium Improves and Prevents Migraines
If you’ve never had a migraine, consider yourself fortunate. They are incredibly debilitating and can cause nausea, light sensitivity and vomiting.
Low levels of magnesium in the body may lead to migraines. Foods high in magnesium are shown to reduce migraine symptoms.
Some studies have shown that magnesium can prevent and even treat those suffering from migraines (16).
One study even showed that taking magnesium during a migraine lessened the symptoms better than a common medication (17).
The Potent Anti-Inflammatory Benefits of Magnesium
In those suffering from chronic disease, obesity and aging you typically see chronic inflammation.

The good news is that magnesium is safe and widely available in many of your favourite foods.
