Quick Summary tl;dr

Combining a ketogenic diet with intermittent fasting sets you up for success by making it easier to manage hunger and maintain steady energy levels. When you’re in ketosis, fasting becomes less of a struggle because your body’s already used to burning fat for energy.

Adding fasting to your keto lifestyle cranks up the fat-burning and could even sharpen your mind and extend your life. It's not just about losing weight; it's about enhancing your overall health and feeling great while doing it.

Jumping into fasting doesn't have to be tough. Start with shorter fasting periods and keep hydrated to ease your body into it. Listening to your body is key—adjust as you go to find what works best for you.

Our app is here to help you merge keto and fasting smoothly. Track your fasting, monitor your progress, and get the guidance you need every step of the way. Whether you’re a beginner or looking to step up your game, our app supports your journey toward better health.

Why Keto Enhances Fasting

When you combine intermittent fasting with a ketogenic diet, managing hunger becomes a whole lot easier. Why? Because keto switches your body’s fuel source from carbs to fats, meaning you start using fat for energy even before your fast begins. ( Paoli et al, 2015)

One of the common struggles with fasting is dealing with hunger pangs that strike when your blood sugar dips. But here’s the kicker: being in ketosis helps keep your blood sugar levels stable, which cuts down those hunger pangs. ( Gibson et al, 2015) This means you can go about your fasting period without the constant battle against cravings and fatigue, making it easier to stick to your fasting plan.

Plus, ketosis boosts the hormone cholecystokinin (CCK), which keeps you feeling full longer. This is super helpful during fasting, as it naturally reduces the urge to snack and helps extend your fasting periods with less discomfort. ( Paoli et al, 2015)

Why Fasting on Keto Might Be More Effective

So why consider fasting if you're already following a keto diet? Combining these two can take your health journey to a whole new level. Here’s how:

Fat Burning Supercharged

On keto, your body is already using fat as its main fuel source. When you add fasting to the mix, you amplify this fat-burning process. This not only aids in weight loss but also helps maintain it over time. By combining keto with fasting, you're tapping into your fat stores even more efficiently, especially during periods when you're not eating. ( Anton et al., 2018)

Steady Energy

One major bonus of keto-fasting is the stable energy levels. Since both keto and fasting help maintain low and stable insulin levels, you avoid the big spikes and drops in energy that carbs often cause. This stability can make it easier to focus and stay active, without the crashes that make you reach for a snack. ( Johnstone, 2015)

Enhanced Brain Health

There’s also something cool about how this combination impacts your brain. Studies suggest that the combination of ketosis and fasting can lead to better brain health and improved mental clarity. This is because both practices are known to increase the production of a brain chemical called BDNF, which helps with learning and memory. ( Mattson et al., 2016)

Increased Longevity

Research is starting to show that the benefits of keto combined with fasting might even extend your lifespan. This is because both practices can improve markers of health like blood sugar control, inflammation reduction, and heart health, which are all linked to longer life. ( Wei et al., 2017)

How To Integrate Fasting into Keto

Merging intermittent fasting with the ketogenic diet doesn’t have to be complicated. Here are some quick tips to help you get started and make the most out of combining these two powerful health strategies.

1. Choosing the Right Time to Start

If you’re new to keto, don't rush it! Give your body a couple of weeks to adjust to this new way of eating before you introduce fasting. This allows your body to get used to burning fat for fuel first, which can make the transition to fasting smoother and more manageable.

2. Start with Gentle Fasting Windows

Begin with shorter fasting periods that feel manageable. A popular approach — and a great way to start — is the 16/8 method, where you fast for 16 hours and eat within an 8-hour window. For example, you might choose to eat between 12 p.m. and 8 p.m., or 10 a.m. and 6 p.m. These schedules can work well with your natural hunger cues while on keto.

3. Stay Hydrated

Drinking plenty of water is crucial, especially during your fasting periods. Hydration helps curb hunger and maintains your energy levels. Don’t forget to include electrolytes like sodium, potassium, and magnesium, which are vital for preventing symptoms of the "keto flu.". Apart from electrolyte drinks and supplements, you can have some bone broth or chicken stock.

4. Monitor Your Body’s Response

Pay attention to how your body reacts. Everyone’s different, and what works for one person might not work for another. If you feel overly tired or irritable, it might be a sign to adjust your fasting window or what you’re eating during your meals. You might want to start with a gentle fast, such as 14/10, during which you'll fast for 14 hours and have a 10-hour feeding window. For example, you might choose to eat between 10 a.m. and 8 p.m.

5. Break Your Extended Fast Gently

When you’re coming off a long fast, such as over 24 hours, it's best to take it slow with your first meal. Your digestive system might be a bit delicate after the break, so starting with something light and easy to digest is key. Think about having a small salad, or maybe a few steamed veggies with some olive oil and salmon. Keep it keto-friendly with high-protein choices. Ease back into your regular meals gradually to keep things comfortable.

I changed the way I ate in 2011, when I was diagnosed with Hashimoto’s, an autoimmune disease that affects the thyroid. I had no energy, and I found it more and more difficult to maintain a healthy weight.

That’s when I decided to quit sugar, grains, and processed foods, and to start following a whole-foods-based ketogenic approach to food.

So excited to get the new fasting update! Love love love it!

Thank you Sarah, I'm glad you like it! There's more features coming soon so stay tuned. I'll be running more polls in the group 😊

Fasting has made a HUGE difference to my progress. Before adding two days of OMAD every week I was just stuck. I couldn't lose anything for months. Now it's melting like butter 😊 Never underestimate the power of keto with fasting! Thank you so much for adding the new fasting feature. Now I no longer need to use and pay for two separate apps!

Thank you for your kind words and support, Amy! Fasting is a game changer for many people! And it gets so easy with keto 😊
