Summary of Why You Need Sodium on a Fast:
*Summary:
– Sodium is an essential nutrient that our body needs for various bodily functions, including maintaining fluid volume, blood pressure, muscle contraction, and nervous system signaling.
– When carbohydrates are restricted or removed from the diet, our kidneys excrete more sodium, leading to increased sodium losses.
– Common symptoms of low sodium levels include headaches, lightheadedness, dizziness, fatigue, nausea, and muscle cramps.
– Lack of sodium can also contribute to feelings of fatigue during a fast.
– Supplementing with sodium during a fast is recommended, with an intake of 2-3 grams per day for non-exercisers and 3-4 grams per day for exercisers.
– Sodium supplementation can be done through various sources like bouillon, mineral water, and salt tabs.
– It is important to discuss your diet and supplementation with a healthcare provider, especially if you have a history of kidney disease, blood pressure issues, heart failure, or if you’re pregnant or on diuretics.

Welcome back to our electrolytes series! In part one, we discussed the importance of magnesium during a fast. Today, we will explore another essential nutrient that is often overlooked – sodium. Yes, sodium, the culprit behind high blood pressure and flavor-enhancing properties of our favorite snacks. But did you know that sodium plays a crucial role in maintaining fluid balance, blood pressure, muscle function, and nerve transmission? Let’s dive deeper into why you need sodium on a fast and how to make sure you’re getting enough.
Imagine a world without sodium. No more savory flavor, no more electrolyte balance, and certainly no more French fries! Our bodies rely on sodium to function optimally. It helps maintain the volume of fluid inside and outside our cells, regulates blood pressure, transports nutrients, and allows our muscles to contract smoothly. Without sodium, our bodily systems would be thrown out of sync. It’s truly a remarkable mineral!
Now, you might be wondering, “But why do I need sodium during a fast? I thought fasting was all about deprivation!” Well, when we fast or restrict carbohydrates from our diet, our kidneys go into overdrive. They start excreting more sodium along with extra fluid. This increased sodium loss can be attributed to the excretion of ketone bodies, as well as changes in glucagon and insulin levels. As a result, our sodium levels can drop, leading to various symptoms.
Have you ever experienced headaches, lightheadedness, dizziness, fatigue, nausea, or muscle cramps during a fast? These could be signs of low sodium levels. It’s important not to dismiss these symptoms as just part of the fasting process. In fact, many people mistake their fatigue for hunger, when it could actually be due to a lack of sodium. The good news is that you can supplement with sodium without breaking your fast!
When it comes to sodium supplementation during a fast, there are a few guidelines to keep in mind. The federal guidelines recommend a daily limit of 2,300 mg of sodium, but some experts argue that our bodies may actually need around 3,500 mg. Studies have shown that negative sodium balance usually occurs on the second day of a fast, with sodium excretion from the kidneys starting as soon as the fast begins. One study estimated a cumulative sodium loss of 7,475 mg over seven days, with a daily peak urinary sodium loss of 1,564 mg on day three.
Based on these findings, it’s recommended to start with 2-3 grams of sodium per day if you’re not exercising during your fast. To put that into context, a teaspoon of pink Himalayan sea salt contains about 1.7 grams of sodium, while half a cube of bouillon provides a little over 1 gram. This means you could have a mug of low-calorie bouillon at mealtimes or chew on pink Himalayan salt crystals to satisfy your sodium needs.
Now, if you’re exercising during your fast, you may require additional sodium to compensate for what you lose through sweat. Drs. Volek and Phinney, experts in low-carbohydrate diets, recommend consuming one additional gram of sodium within an hour before exercise to account for these extra losses. So, for those who are hitting the gym or engaging in physical activity while fasting, that would mean consuming 3-4 grams of sodium per day, with a gram of that being consumed before the workout.
When it comes to supplementing with sodium, the options are quite versatile. You can choose bouillon, mineral water, or salt tabs, as long as the calorie content remains minimal. At Zero, we find that a mug of low-calorie bouillon at mealtimes provides both the satisfaction of consuming something savory and the necessary sodium supplementation. Some of us even enjoy chewing on pink Himalayan salt crystals, giving our teeth something to do during the fasting period!
However, it’s essential to remember that not everyone should supplement with sodium without caution. Certain populations, such as those with a history of kidney disease, blood pressure issues, heart failure, or individuals who are pregnant or on diuretics, should consult with their healthcare provider before making any changes to their diet or supplementation. Your healthcare provider can provide personalized guidance and ensure you’re making the right choices for your unique situation.
To sum it all up, supplementing with magnesium and sodium during a fast can significantly enhance your fasting experience. For magnesium, aim to supplement just above 100% of the recommended daily allowance (RDA) and opt for various molecular forms, including slow-release magnesium, to maintain a steady drip of magnesium in your bloodstream. When it comes to sodium, aim for 2-3 grams per day if you’re not exercising and 3-4 grams per day if you are. Remember that sodium supplementation during a fast can be done through various sources like bouillon, mineral water, or salt tabs. Just ensure you’re not exceeding your caloric limit.
In conclusion, sodium is not just the villain behind high blood pressure. It plays a crucial role in our bodily functions, especially during a fast. By ensuring you’re getting enough sodium, you can mitigate symptoms like headaches and fatigue, making your fasting journey a lot more pleasant. So, grab that mug of bouillon or those pink Himalayan salt crystals and give your body the sodium it deserves! And don’t forget to consult with your healthcare provider to address any specific concerns or considerations regarding sodium supplementation during a fast. Stay hydrated, stay nourished, and happy fasting!
