Your Breath Smells Like Ammonia
While stanky breath that reminisces of nail polish remover is a normal side-effect on keto, breath that smells like ammonia is not.
Interestingly enough, ammonia is produced by the body when it digests and breaks down protein, Long explains. When you ingest large amounts of protein, ammonia production can make your breath smell.
So, if your breath smells like Windex, your protein intake may be high enough that its pulling you out of ketosis.
What Causes Protein To Inhibit Ketosis
It all starts with the Krebs cycle, that metabolic pathway that converts fatty acids into useable energy. In a normal cycle, fatty acids are broken down into acetyl-CoA. The liver pairs acetyl-CoA with oxaloacetate to complete the cycle and produce ATP energy. Thats basic energy generation.
Without oxaloacetate, the Krebs cycle cannot continue. Without oxaloacetate, acetyl-CoA has a different energetic fate: conversion into ketones. Where does oxaloacetate come from?
Carbs, usually. But protein can also be a source. Like carbohydrates, protein has the potential to donate oxaloacetate during the Krebs cycle. The more protein you eat, the more oxaloacetate youll have ready and willing to inhibit ketogenesis. This is how protein inhibits ketosis. Not by increasing gluconeogenesis. Not by spiking insulin.
How Your Body Responds To Protein Intake
Protein digestion and assimilation are such intricate processes that we are only going to explore the main pieces that pertain to ketosis and keto dieting in this article. More specifically, we will be focusing on our hormonal response to protein intake.
When protein is digested, it will trigger the release of two energy-regulating hormones: insulin and glucagon. The degree to which each hormone is released depends on many factors including the macronutrient makeup of the persons diet, their gender, their activity levels, and if they have diabetes.
Whats fascinating about these two hormones is that they have opposing functions:
- Insulin stimulates the uptake of sugar into cells, sugar burning, and anabolic processes like glycogen storage and protein synthesis , while also reducing lipolysis and gluconeogenesis .
- Glucagon triggers glycogen breakdown, lipolysis, fat burning, and gluconeogenesis.
For keto dieters, the most striking effect these hormones have is that they have opposing influences on ketone production. Insulin decreases ketone production while glucagon stimulates it.
The ratio of insulin to glucagon is one of the main factors that determines how your protein intake will affect your ketone levels. For example, if you secrete much more insulin than glucagon in response to a protein feeding, then ketone production will be reduced. On the other hand, when more glucagon is released, ketone production will be stimulated.

Tips For Further Customization Of Your Protein Intake
Do I Need More Protein If I Train Really Hard
While protein intake is important to fuel muscle growth and repair, research suggests that you don’t need to go crazy.
A study in the 80s followed elite bodybuilders who trained 90 mins a day, 6 days a week. When it came to benefiting body composition, the upper limit of protein intake was 0.75 g/lb . In fact, its well documented that more advanced trainees may require less protein than novice athletes .
Its important to note that this figure of 1.65 g/kg would be the upper limit for muscle gains if you are in a caloric balance .
However, as we touched on earlier, if youre consuming a caloric deficit and looking to lose weight, you may benefit from a higher protein intake to help preserve or build lean muscle mass – upwards of 2.4 to 3 g/kg per day .
How To Reduce Protein On Keto
One option is to eat higher fat cuts of meat and less lean meat like chicken breast and turkey. If you keep your portion size small, this will increase your fat intake while keeping protein low.
Alternatively, eat less protein overall and ensure you are getting plenty of fat from non-meat sources like avocado, olives, butter, dairy and oils.
How Much Meat To Eat
Meat supplies a whole range of nutrients including nutrients like vitamin B12 that you cant get anywhere else. Its also a key source of protein for keto diets. At the very minimum, humans need to eat enough protein to repair our muscles and do all the other important stuff that protein does. So enough meat means enough to serve as a primary protein source and round out your diet with essential nutrients that are mainly or only found in meat.
The short version: if you eat meat or eggs at 1 to 3 meals a day, with supplemental protein at any non-meat meals, youll probably get plenty of protein for keto plus enough of all the other nutrients in meat. Scroll down to the list below for suggested serving sizes.

How Much Protein To Eat On Keto
The Standard American Diet is dense in carbs, with some protein and very little fat. On keto, you take a seemingly opposite approach, with the bulk of your calories coming from fat, some calories coming from protein, and very few from carbohydrates.
While every person has individual needs, most people follow these macronutrient guidelines to enter ketosis:
- 75-80% of calories should come from fat
- 20% of calories should come from protein
- 5% of calories should come from carbohydrates
This is a common way to break down your macros on the ketogenic diet. And while it may help you to start producing ketones, it may not be the most effective approach for overall body composition and weight loss.
Instead of setting up macronutrient percentages, theres a better alternative.

Choosing Keto Friendly Protein Sources
While there are many plant-based keto friendly protein sources, were going to focus on animal products in the guide. Know that foods like nuts and seeds do contain protein, but also tend to have higher carbs than animal sources of protein.
Not all protein is created equal for keto. By that, we mean some cuts of meat will tend to be more keto friendly than others . Below well outline the best cuts of meat to include on a keto diet. Whenever possible, we recommend choosing meat from local, and sustainable sources. All Ketolibriyum poultry and beef is sourced from local farms that do not use antibiotics or hormones in producing their meat. We also try to source local pork as much as possible.
A note on eggs: Eggs are an amazing source of keto friendly protein! Eating four eggs per day would get you between 20-25 grams of protein.
How To Get Your Protein Intake On Track
If youre unsure whether your keto diet is actually too high in protein, youll first need to get a clearer picture of your intake. To do so, Long recommends tracking your food in an app for at least a few days. If youre eating more than about 20 percent of your daily calories from protein, youll need to adjust your meals and snacks to tone it down.
Another surefire way to test whether your keto diet is actually achieving its purpose: Test your ketone levels. Using at-home strips, you can tune into the amount of ketones present in your urine, and make sure levels are in the true ketosis range. Many test stripslike Finaflexs Ketone Test Stripsstart off beige in color, and take on a pink or purple hue, depending on the amount of ketones detected. If you dont fall into the optimal range, take a look at your protein intake and adjust as needed.

How Much Protein To Eat On A Keto Diet
How much protein you need on a keto diet depends on your unique body and goals. Using the example of a 140-lb person, you would multiply that number by 0.6 to get your minimum protein amount .
You can then do the same for your maximum protein intake by multiplying by 1 , which gives you an ideal intake range. In this case, would be between 84-140 grams of protein per day.
You can also use an automated keto macro calculator. Its quick, easy, accurate, and takes your unique measurements into account.

How To Calculate Carbs
For anyone on the keto diet, it is important to consider the number of net carbs in foods. A person can calculate the number of net carbs in a serving by subtracting the amount of fiber from the total number of carbs. If the food is processed, a person should also subtract half the sugar alcohol content. These quantities are included on food labels.
We look into these terms and the calculation in more depth below:

How Much Protein Should You Eat On Keto
How much protein you should eat on Keto for optimum results is widely contested…
Some believe that too much protein may be detrimental and could throw you out of Ketosis.
Others argue that too little can hamper recovery, decrease lean muscle mass, and make it harder to lose weight.
In this article, well take a deep dive into all things protein and Keto to help clear up any confusion.
Is Keto Bad For The Kidneys
There is a long-held notion among the general population that the kidneys are the major site of protein metabolism and a high-protein diet is bad for the kidneys. This presumption is flawed for several reasons…
Firstly, protein is predominantly metabolized in the gut since the enzymes that hydrolyze polypeptides into individual amino acids and oligopeptides are primarily located in the stomach.
Once protein is sufficiently broken down, the short amino acid chains and isolated amino acids may go on to play a myriad of biological roles, such as helping synthesize new muscle tissue, producing neurotransmitters, and providing energy for cells.
The kidneys arent necessarily involved in protein digestion rather, they help remove the metabolic waste that develops as a byproduct of protein metabolism. In humans, the major byproduct of protein metabolism is ammonia, which is subsequently converted to urea in the liver and then transported through the blood to the kidneys so it can be filtrated and excreted via urine.
Technically, the urea cycle in the liver is the final point of protein metabolism.
Thus, the kidneys are like the trash collectors of the body since they pick up this metabolic waste from protein metabolism and help flush it out of the system.
But before you go and slam another scoop of protein powder, there are some finer points to consider when it comes to a high-protein keto diet and kidney health.

Clean Keto Calls For Eating Organic Versions Of Foods
How It Works Swinging in the opposite direction of the dirty keto approach is, naturally, clean keto. But its not a full 180, because you can still focus on convenience, says Raymore, Missouri-based Randy Evans, RD, consultant for Fresh n Lean, a meal delivery service specializing in keto foods. You also will still stick to the same macronutrient distribution as standard keto. The difference is that clean keto is based on sourcing the healthiest versions of foods. That means youll look for terms like organic, grass-fed, pasture raised, and cold-pressed. Youll also lean heavily towards whole plant foods, Evans says.
Who It’s Best For This approach is for those who focus on food quality just as much as they do on macro tracking. Also, clean keto may involve more financial investment, since grass-fed meats and cold-pressed extra-virgin olive oil tend to be pricier than lower-quality options, especially those packaged for convenience.
Risks to Note Focusing on the healthiest possible foods and bringing in a fridge-load worth of plants in the process doesnt include many cautionary notes, according to Evans. That said, because plant foods still contain carbs, youll need to keep your macros in mind. If you can, this can be a relatively healthier way to do the fad diet.
Guidelines For Individualized Protein Intake
Taking into account the different positions among keto and low-carb experts, we recommend a protein intake of 1.2 to 2.0 grams per kg of body weight for most people. Protein intake within this range has been shown to preserve muscle mass, improve body composition, and provide other health benefits in people who eat low-carb diets or higher-carb diets.9
If youre near your ideal body weight or very muscular, use your actual weight to calculate your protein needs. Otherwise, you can use your height and the chart below to estimate how much protein you should aim to eat on most days.
