Should You Take Supplements On A Low-Carb Diet?

In my 15 years of clinical practice, I’ve observed the rising popularity of low-carb diets. From celebrities to my own patients, many have turned to this approach for its promising health benefits.

But as with any star, there’s always more than meets the eye. While these diets promise rapid weight loss and improved energy, they also come with their own set of challenges.

Enter the world of supplements, the unsung heroes that bridge the gap between our dietary choices and our body’s essential nutrient needs.

The Science Behind Low-Carb Diets

Ketosis: The Body’s Power Switch

Imagine your body as a hybrid car. Typically, it runs on glucose (carbs), much like a car runs on gasoline. But when carbs are scarce, it switches to burning fat, similar to how some cars switch to electricity ¹.

This process is called ketosis. When in ketosis, the liver breaks down fats into ketones, which then serve as a primary energy source. It’s like your body’s eco-mode, optimizing energy usage and burning stored fat.

A Historical Dive: The Ketogenic Diet and Epilepsy

During my research at Stanford University, I delved into the historical origins of the ketogenic diet. Contrary to popular belief, its foundations can be traced back to ancient Greece.

Physicians noted that fasting reduced seizures in people with epilepsy. Fast forward to the 1920s, and the ketogenic diet was introduced as a way to mimic the benefits of fasting without the need to stop eating altogether ².

It was a game-changer, providing relief for many epilepsy patients, especially children. Today, while its use has expanded to weight loss and other health benefits, its historical significance in epilepsy treatment remains a testament to its power.

Common Challenges with Low-Carb Diets

Here’s a visual representation of the common challenges and we’ll dive further into each one.

The Keto Flu: More Than Just a Sniffle

As you embark on your low-carb journey, you might encounter the infamous “keto flu.” But fear not, it’s not an actual flu!

It’s a collection of symptoms that can occur as your body adjusts to its new fuel source ³.

Symptoms include:

• Fatigue
• Headaches
• Irritability
• Difficulty sleeping
• Nausea

Remedies:

• Stay hydrated.
• Increase salt intake.
• Consume bone broth.
• Rest and give your body time to adjust.

The Constipation Conundrum

Cutting carbs often means cutting fiber-rich foods like fruits, grains, and legumes. The result? A potential slowdown in the digestive department.

Causes:

• Reduced fiber intake.
• Dehydration.
• Electrolyte imbalances.

Solutions:

• Incorporate low-carb, high-fiber foods like avocados, nuts, and seeds.
• Drink plenty of water.
• Consider a fiber supplement.

Dehydration: The Sneaky Side Effect

When you cut carbs, your body sheds water and electrolytes at a rapid pace. This can lead to dehydration, which can exacerbate other side effects of the diet ⁴.

Why it happens:

• The body burns through glycogen (stored carbs) which releases water.
• Production of ketones can have a diuretic effect.

How to combat it:

• Drink water throughout the day.
• Add a pinch of salt to your water or foods.
• Consume foods rich in potassium and magnesium, like leafy greens and nuts.
