The Ultimate Electrolyte Recipe for Fasting

Feel Weak While Fasting? You Might Be Missing This One Thing

When you’re fasting, you’re doing something powerful for your body. But if you’re feeling tired, dizzy, or just “off,” it’s probably not hunger — it’s electrolytes. These tiny minerals are the secret to feeling great during your fasts. Without them, your energy crashes. Your head pounds. You feel like quitting. But there’s good news — it’s easy to fix.

Why Electrolytes Are Critical When Fasting

Fasting changes how your body handles salt and water. As insulin drops, your kidneys flush out excess fluids — and along with them, vital electrolytes like sodium, potassium, and magnesium. These minerals power everything from muscle contractions to brain signals. When they’re low, your body starts warning you: headaches, fatigue, cramps, brain fog, even heart palpitations.

Replenishing electrolytes isn’t optional. It’s the difference between powering through your fast or giving up halfway. If you’ve ever hit a wall on day 2 or 3 of a fast, it likely wasn’t willpower — it was missing minerals.

The Problem with Store-Bought Electrolyte Products

When you look for help, you’ll find shelves full of “electrolyte drinks.” Sports drinks, hydration powders, even water enhancers. But read the label and you’ll see the problem: most are loaded with sugar, artificial flavors, and other junk that breaks your fast or messes with your gut.

Some contain more sugar than a soda. Others sneak in fake sweeteners or additives that spike insulin — the very hormone you’re trying to lower by fasting. Even “keto-friendly” options can have ingredients that trigger cravings or throw you out of ketosis.

You deserve better. You need clean, fasting-safe electrolytes. But most companies aren’t giving you that.

The Scandal with Maltodextrin and LMNT

Let’s talk about a name you’ve probably heard: LMNT. It’s one of the most popular electrolyte brands in the fasting and keto world. Their marketing is slick. Their influencers are everywhere. And their price tag? Up to $45 for a month’s supply.

But what they don’t tell you could make you think twice.

In 2023, a controversy broke out when independent lab testing suggested that LMNT’s “raw unflavored” formula contained maltodextrin — a hidden carb that spikes blood sugar faster than table sugar. Maltodextrin doesn’t have to appear on the label in trace amounts, but for a fasting product, even a small amount can sabotage your results.

LMNT denied any wrongdoing. But the lab reports were public, and many in the fasting community felt betrayed. After all, you trusted this product to support your fast, not sneak in hidden sugars.

This wasn’t just about LMNT. It was a wake-up call. If even the most trusted brands can cut corners, how can you be sure what you’re putting in your body?

The Solution: Make Your Own Electrolytes

Here’s the truth: you don’t need to buy expensive mixes or risk hidden ingredients. Making your own electrolyte drink at home is simple, cheap, and completely under your control. No sugar. No fillers. No mystery.

All you need are three basic minerals:

• Sodium (sea salt or Himalayan salt)
• Potassium (potassium chloride, available as “NoSalt” or “Lite Salt”)
• Magnesium (magnesium citrate or glycinate powder)

Mix these with filtered water, maybe a squeeze of lemon or a splash of apple cider vinegar for taste — and you’re good to go. Your homemade mix works better than anything on store shelves because it’s tailored to real fasting needs, not mass market sales.
