Ketones: Your Body’s Super Fuel

Have You Ever Wondered What Happens When Your Body Runs Out of Sugar for Energy?

My name is Dr Nelum, and for years, I struggled with weight gain, poor sleep, brain fog, and irritability. Then, I discovered fasting, ketosis, and ketones. Everything changed from there!

The first time I fasted beyond 16 hours, something incredible happened. My mind felt clearer, I felt calmer, and I could see things more clearly—almost like someone had lifted a fog off my brain. I wasn’t jittery from caffeine or crashing from sugar. It was this steady, even energy that I’d never experienced before.

What I experienced was my body switching from using glucose as fuel to using ketones—an alternative and highly efficient energy source that’s derived from burning fat.

What Are Ketones?

Ketones are molecules produced by the liver when the body burns fat for energy instead of glucose. They are created in response to low insulin levels, usually during fasting or a low-carbohydrate diet.

When glucose is scarce, the body taps into stored fat, breaking it down into fatty acids. The liver then converts these fatty acids into ketones, which can be used as fuel by every cell in the body, including the brain, heart, and muscles.

I like to think of this process as flipping a switch from running on unreliable fuel to running on a premium energy source. The result? More energy, better focus, and fewer cravings.

Benefits of Ketones

Switching to ketones as a primary energy source comes with a host of benefits:

• Used by Every Cell in the Body – Unlike glucose, which requires insulin to enter cells, ketones are easily absorbed and utilized.

• Burned from Stored Body Fat – A natural and sustainable way to lose fat while maintaining energy levels.

• Less Oxidative Stress – Ketones produce less oxidative stress compared to glucose, meaning less cell damage and inflammation.

• Potent Hunger Suppressant – When I am in ketosis, I feel full for longer, making it easier to maintain a healthy diet.

• Enhanced Brain and Heart Function – My brain prefers ketones as an energy source, leading to improved mental clarity and cognitive function.

• Neuroprotection – Studies suggest ketones may protect against neurodegenerative diseases like Alzheimer’s.

• Mood Stabilization – My mood and emotional balance have improved significantly since switching to ketosis.

• Better Sleep and Less Irritability – Since adopting a ketogenic lifestyle, my sleep has improved, and I feel more emotionally balanced.

Ketosis is particularly beneficial for the management of certain medical conditions, including epilepsy, severe mental health conditions, Alzheimer’s, and cancer. Ketone supplements can be particularly useful for those managing these conditions, providing an additional source of ketones for energy and therapeutic benefits.

Before I started fasting and eating keto, I would have mood swings and energy dips. Now, I feel steady throughout the day—no crashes, no sugar cravings. It’s life-changing.

How to Increase Ketone Levels

Want to experience these benefits for yourself? Here are some ways to boost ketone production and shift your body from relying on glucose to burning fat for fuel:

1. Fasting (Intermittent or Prolonged)

One of the most effective ways to enter ketosis is fasting. When you fast for 16-24 hours, your body runs out of stored glucose and starts producing ketones. The longer you fast, the higher your ketone levels.

My fasting routine varies. Some days, I do intermittent fasting (16-18 hours), while other times, I do a 24-hour or even 48-hour fast. After 17 hours, I feel the mental shift—everything gets sharper, and I feel a sense of calm focus.

2. Ketogenic Diet (Low-Carb, High-Fat)

The ketogenic diet is another way to achieve ketosis. By keeping carbs low (20-50g per day) and increasing healthy fats, your body naturally starts producing ketones.

I follow a ketogenic diet on most weekdays, enjoying foods like eggs, avocados, fatty fish, and nuts. I used to fear fat, but now I understand that healthy fats are my body’s best friend. They keep me full, my energy stable, and my mind clear.

3. Carnivore Diet

A carnivore diet, which eliminates all carbohydrates and focuses on animal-based foods, is an extreme but effective way to sustain ketosis.

While I don’t follow a strict carnivore diet, I occasionally incorporate it into my routine, enjoying steak, butter, and bone broth. It’s a great reset when I want to simplify things.

4. Supplementation

For those who need an extra boost, exogenous ketone supplements can provide ketones without waiting for the body to produce them naturally. These can be useful during the transition phase when shifting into ketosis and are particularly beneficial for individuals managing epilepsy, severe mental health conditions, Alzheimer’s, and cancer.

Signs You’re in Ketosis

How do you know if your body is producing ketones? Here are some telltale signs:

• Increased Mental Clarity – A sharp, focused mind, free from brain fog.

• Reduced Hunger and Cravings – Feeling full longer and having fewer food cravings.

• Stable Energy Levels – No energy crashes or afternoon slumps.

• Fat Loss – Especially around the midsection, where the body stores excess fat.

• Keto Breath – A distinct, fruity breath odor due to acetone, one of the ketone bodies.

Keto breath was a surprise at first. But once I realized it was a sign of being in ketosis, I saw it as a badge of honor!

Takeaway: Harnessing Ketones for Optimal Health

Ketones are your body’s natural super fuel. They provide a cleaner, more efficient energy source, helping with weight loss, brain function, and overall well-being.

To experience the benefits of ketones:

• Try a ketogenic or carnivore diet

• Incorporate fasting into your routine

• Consider exogenous ketone supplements (especially if managing certain medical conditions)

My journey is proof that switching to ketones can be life-changing. I no longer struggle with energy crashes or cravings. Instead, I enjoy mental clarity, stable moods, restful sleep, and a body that burns fat efficiently.

I used to rely on coffee and sugar to get through the day. Now, I rely on my own body’s energy system. And it’s the best decision I’ve ever made.
