What are Electrolytes and Why do You Need Them

You hear about electrolytes everywhere, but what exactly are they? Think of electrolytes as tiny electricians working inside your body. They're minerals that carry electrical charges and help your body's electrical system work properly.

Your body runs on electricity. Every time your heart beats or your muscles move, tiny electrical signals make it happen. Electrolytes make these signals possible. The main ones are sodium, potassium, magnesium, and calcium.

Electrolytes don’t directly cause fat loss, but they’re key to making weight loss easier and healthier. Minerals like sodium, potassium, and magnesium regulate water balance, energy, and muscle function. So if they’re low, you might feel tired, crampy, or bloated.

By keeping electrolytes balanced, you’ll have steadier energy, better workouts, and fewer setbacks as the pounds come off.

What happens when you’re low on electrolytes

Constant fatigue that sleep doesn't fix is the biggest clue. If you wake up tired even after sleeping well, electrolytes might be the problem.

Muscle cramps and random twitches are your body asking for more minerals, especially magnesium and potassium. This includes restless legs at night or that annoying eyelid twitch.

Headaches and brain fog often come from electrolyte imbalance, not just dehydration. You need both water and minerals to feel sharp and energized.

Best food sources

Potassium: Bananas, potatoes with skin, avocados, and coconut water (nature's perfect sports drink).

Magnesium: Dark leafy greens, pumpkin seeds, almonds, and dark chocolate.

Sodium: Natural sources like miso soup, sea salt, or pickled vegetables work better than table salt.

Asian superfoods: Seaweed (nori, wakame) and fermented vegetables like kimchi provide multiple electrolytes plus probiotics.

Simple daily fixes

Add a pinch of sea salt to your water, especially if you're drinking large amounts. Plain water can actually dilute your minerals if you drink too much without electrolytes.

Eat potassium-rich foods daily. A banana or handful of spinach in a smoothie makes a big difference. Don't skip meals when you're stressed or active, as your body burns through electrolytes faster during these times.

Track what works

In the custom diet preferences setting (Settings > Allergies and Restrictions) you can tell Welling you want to increase your electrolytes intake. It will help you prioritize those foods.

Bottom line: Electrolytes affect your daily energy, sleep, and focus. Focus on whole foods, add natural salt to water, and listen to your body's signals.
