Will Too Much Protein Bump Me Out of Ketosis

author avatar Dr. Eric Berg 09/22/2023

Ever wondered how that extra scoop of protein powder impacts your journey into ketosis? Like navigating a complex labyrinth, understanding the effects of excessive protein on our bodies can be tricky.

Picture this: You're diligently following a low-carb diet to enter ketosis, but there's an unexpected twist - too much protein is throwing you off course.

Beneath its deceptively simple facade, the human body is far more intricate than we often assume. It's not just about consuming less carbs and more proteins. Excess protein might even mimic carbs in specific ways! Confusing right?

Well, worry no more! This guide promises insights into why too much protein could hamper your progress toward achieving ketosis.

We'll delve deep into gluconeogenesis and reveal how dietary proteins transform into glucose in your body.

Also, you'll uncover the intriguing effects of combining carbs and proteins.

Understanding Ketosis and Protein Consumption

The relationship between ketosis and protein consumption is like a dance. Consuming protein alone is not enough to achieve ketosis; there must be a balance between carbohydrates and proteins. In fact, in a low-carbohydrate environment, protein behaves differently.

The Role of Protein in the Body

Protein plays a crucial role in our bodies, but it's often misunderstood. The suggested consumption is around 0.7 g for every kilogram of lean body mass. Studies show that proteins are meant to replace parts of your body tissue rather than acting as a backup fuel source.

The Impact of Excessive Protein on Insulin Levels

Overeating protein can cause issues you might not expect - especially regarding insulin levels. Amino acids from excess protein stimulate insulin secretion just like carbohydrates do.

Research suggests that insulin secretion may double if these amino acids are consumed while blood glucose concentration is elevated.

It's an intricate balancing act – consuming enough for repair without going overboard so you don't interrupt ketosis or spike your insulin levels.

The Process of Converting Protein into Glucose

Our bodies are intricate, constantly seeking methods to obtain the energy they require. One surprising method is turning protein into glucose, a process called gluconeogenesis.

Understanding Gluconeogenesis

Gluconeogenesis isn't your body's first choice for fuel. It would instead use carbs or fats before tapping into your protein stores. On a low-carb diet like keto, the body must use dietary protein for glucose if it cannot get enough from fat and carb sources.

Your body will start using dietary protein to make glucose if it needs more than what's available from fat and carb sources.

That means if you overeat protein while trying to stay in ketosis, that extra can be converted into glucose and potentially knock you out of that desired state. Studies have shown this happens mainly with dietary proteins, not stored ones.

If you're aiming for ketosis, this may seem bad news but don't fret. There's plenty we can do about it, which we'll explore later in our discussion on balancing diet for optimal ketosis.

The Dangers of Combining Carbs with Protein

When aiming for ketosis, be aware of what you consume, as combining carbs and protein can interfere with your goals. Mixing carbs and protein can throw a wrench in your plans.

The Impact on Blood Glucose Levels

Consuming carbs alongside protein might seem harmless, but the effects are more than meets the eye. This combination leads to elevated blood glucose levels, creating an uphill battle for those trying to achieve or maintain ketosis.

Eating foods high in both carbohydrates and proteins triggers insulin release. Insulin helps shuttle glucose from our bloodstream into cells, where it’s used as energy or stored as fat.

Research suggests that consuming too many carbs with protein interrupts this process by overloading our bodies with sugar.

With its high concentrations of carbs and proteins, the SAD may be particularly troublesome for our bodies' ability to process sugar. Studies show that this dietary pattern may increase risk factors for various health issues due to constant exposure to excessive sugars and fats.

In contrast, when we limit carb intake while maintaining adequate protein consumption—as in the keto diet—our bodies start burning fat instead of glucose. That’s how we get into a state called ketosis.

Remember folks. Too much cake—and steak—at once could kick us out of this desirable metabolic state.

Strategies to Maintain Ketosis with Adequate Protein Intake

Determining the proper amount of protein for keeping ketosis is essential. How do you work out what's the ideal amount? Let's get into it.

Determining Your Protein Needs

Your lean body mass, or LBM, can help guide your protein intake. LBM is your total weight minus any fat content.

A simple way to calculate this is using a Lean Body Mass Calculator.

Once you have determined your LBM, aim for approximately 0.7 grams of protein per kilogram daily.

Balancing Your Diet for Optimal Ketosis

Achieving and maintaining optimal ketosis requires careful attention to your diet. When in ketosis, the body relies on fat as its primary energy source, producing ketones, which can sometimes result in sweat smelling like ammonia because of ketosis.

Focus on consuming high-quality fats, moderate protein, and minimal carbohydrates. Healthy fats such as avocados, nuts, and olive oil can provide essential nutrients while keeping you in ketosis.

Remember that individual responses to ketosis can vary, so monitoring your body's signals, including sweat odor, can help fine-tune your diet for the best results.

If you experience persistent issues or discomfort, consult a healthcare professional for personalized guidance on maintaining ketosis and overall well-being.


Cracking the code of ketosis isn't a walk in the park, especially when understanding the effects of excessive protein consumption on ketosis.

We've discovered the critical importance of proteins in our bodies, mainly for restoring tissue and not as an energy source. We discovered how too much protein can spike insulin levels, potentially disrupting your ketogenic journey.

The gluconeogenesis process was unmasked - showing us how dietary proteins can transform into glucose. This reality is even more glaring when we combine carbs with proteins, increasing blood sugar levels.

Yet all hope's not lost! By figuring out your unique protein needs and balancing your diet accordingly, you're on track toward achieving optimal ketosis without hiccups!

You got this! Keep going strong!
