Is it better to go over fat or protein on keto?

#1: Protein Helps With Fat Loss Most people on keto will limit their protein to 30-40 grams, restrict their net carbs to 10-20 grams, then eat an excessive amount of fat. This is a common mistake. If your goal is to lose fat, increased protein consumption is a great way to approach your keto diet plan.

Check your email to get started with the program. The low-carb approach can boost your ketone levels and help you enter nutritional ketosis, which is a metabolic state in which you burn fat (ketones) for energy instead of glucose. This is the defining difference between the ketogenic diet and Atkins or other low-carb diets, which reduce some carbs and don’t try to put you in ketosis. While controlling carb intake is essential on keto, so too is monitoring protein intake. On keto, you’ll consume adequate amounts of protein — never less than you need. This macro is one of the most challenging to nail down when starting keto due to all the conflicting information about it. Protein is a building block of life and a necessary component of any diet. It’s crucial for[*]:

Healthy brain function

Skin, bone, and muscle health

Building muscle mass

Recovering after workouts

Cutting body fat

These benefits promote longevity, prevent injuries, and boost your metabolism.

Unfortunately, a lot of ketogenic dieters are worried that overeating protein might kick them out of ketosis. Many low-carb, high-fat advocates believe excess protein can turn into sugar in your bloodstream through a process called gluconeogenesis and knock down your ketone levels. But as you’ll find out, this is only a myth.

Is Too Much Protein Keto-Friendly?

Eating too much protein is one of the biggest concerns for people who are just starting the ketogenic diet. After all, the body produces ketones from fat, so you should keep carbs and protein down to a minimum, right? Not necessarily. Browse our curated collection of fan-favorites and discover your new favorite snack or supplement. Shop Best Sellers Carbs are the only macronutrient that can seriously interfere with ketosis, which is why it’s essential to watch out for hidden carbs and find the carb limit that works for you. On the other hand, eating protein won’t affect your ketone levels. You can eat high-fat and high-protein (preferably fatty cuts of grass-fed meat) and stay in ketosis. That’s why many people who transition from keto to the carnivore diet have no problem staying in nutritional ketosis.

But what about gluconeogenesis (GNG)?

GNG is a real and necessary process that is already happening in your body. It’s not the enemy of ketosis. In fact, it makes ketosis possible in the first place.

Calculate Your Macros With the Keto Calculator

To find out how much protein you should be eating on keto for optimal health, calculate your keto macronutrients using the free Perfect Keto macro calculator. Surprised about your protein results? Here’s why eating high protein on keto is beneficial.

The High-Protein Myth: Do Not Fear Gluconeogenesis

There’s a widely-circulated claim that excess protein is detrimental to ketosis because it causes gluconeogenesis. This myth has since been disproven. However, there are plenty of articles published online stating this false claim, so it is important to understand how GNG works on ketosis. Gluconeogenesis (GNG) is a metabolic pathway that allows your liver and kidneys to make glucose from non-carbohydrate sources.

The word gluconeogenesis has three parts to it:

Gluco: coming from the Greek root glukos – literally meaning “sweet wine”

coming from the Greek root glukos – literally meaning “sweet wine” Neo: “new”

“new” Genesis: “creation”

Think about GNG this way: It’s how your body creates new sweet wine for your body. This process is unique because it’s the creation of glucose from anything but carbs. Your body takes compounds like lactate, amino acids (protein), and glycerol to manufacture glucose when there are no carbs around. This may seem like a problem when you’re trying to run on ketones instead of glucose, but the truth is gluconeogenesis has an incredibly important purpose — and no, it doesn’t harm ketosis. Some people tout that you don’t need carbohydrates to survive, which is only partially true. To clarify, you don’t need to eat any high-carb foods to survive, but make no mistake — your body needs glucose and glycogen to keep you healthy (even in ketosis), and it will get this via survival mechanisms like gluconeogenesis.

Why Gluconeogenesis Is Vital

On a keto diet, your body uses gluconeogenesis for three primary purposes.

Preventing hypoglycemia: Your glucose levels can never drop to zero, even in ketosis. GNG keeps your blood sugar in a healthy range, so it doesn’t fall to dangerous levels (aka hypoglycemia)[*]. Your glucose levels can never drop to zero, even in ketosis. GNG keeps your blood sugar in a healthy range, so it doesn’t fall to dangerous levels (aka hypoglycemia)[*]. Fueling tissues that can’t use ketones: There are a handful of cells in your body that can only use glucose to survive, including red blood cells, kidney medulla (inner part of the kidney), testicles, and some portions of your brain. Ketones can cover up to 70% of your brain’s energy needs, while the glucose from GNG covers the rest. The other organs can’t metabolize ketones at all. This is why gluconeogenesis provides them with enough glucose to remain healthy[*].

This is why gluconeogenesis provides them with enough glucose to remain healthy[*]. Resupplying glycogen stores: You can replenish muscle glycogen through the GNG that happens during ketosis — at least if you’re not a professional athlete or participate in competitions. Glycogen is crucial for muscle recovery after workouts[*]. If GNG didn’t make enough glucose to cover these functions, your body could never make the switch to using ketones for energy because some cells (like red blood cells) would die, and your blood sugar would drop too low.

Gluconeogenesis makes ketosis possible.

Can Excess Protein Increase Glucose From GNG?

GNG is an extremely stable process. It’s not easy to increase it even with extra protein. Gluconeogenesis (making glucose from non-carbs) doesn’t work at the same rate as carbohydrate metabolism (making glucose from carbs). When you eat chocolate cake, your blood glucose quickly spikes in response to that sugar. When you eat extra protein, your blood glucose doesn’t spike the same way. Studies have shown that GNG production doesn’t increase even with extra amino acids[*].

By now, the following things are clear:

Gluconeogenesis is the process of creating internal glucose from non-carb sources, including protein.

Gluconeogenesis is necessary for survival.

Gluconeogenesis makes ketosis possible.

Eating too much protein won’t increase the rate of gluconeogenesis.

But eating protein isn’t just safe; it’s necessary.

3 Reasons Why You Should Eat More Protein on Keto

Eating adequate amounts of protein is beneficial on the ketogenic diet. It helps your body stay in fat-burning mode, it has fewer calories, and it’s dangerous to not eat enough protein.

#1: Protein Helps With Fat Loss

Most people on keto will limit their protein to 30-40 grams, restrict their net carbs to 10-20 grams, then eat an excessive amount of fat. This is a common mistake. If your goal is to lose fat, increased protein consumption is a great way to approach your keto diet plan. Here’s why[*][*]:

Protein is more satiating than fat

Protein is very nutrient-dense

People tend to overeat when protein is low

If you eat too much fat, your body will burn that new fat coming in and won’t get the chance to burn your stored fat reserves. You can overcome weight loss plateaus by increasing protein and lowering your fat consumption.

#2: Protein Provides Fewer Calories Than Fat

Your body needs to use more energy (calories) to burn protein than to burn fat. For example, when you eat a 100-calorie serving of grass-fed beef, your body can only store 75% of it as calories because it requires 25% of calories to burn it and use it as fuel. Conversely, when you consume fat, you are storing up to 98% of it as calories[*]. This means you’re storing almost all of the calories from fat, whereas you’ll store less from protein since you use up some of the calories to burn it.

#3: Protein Deficiency Is Dangerous

Not eating enough protein on keto has serious side effects, including:

A deficiency in the amino acid arginine can contribute to the dysfunction of your T cells — the cells that regulate your immunity. Increased risk of diseases: A deficiency in amino acids can increase the risk of developing certain diseases, including sickle cell disease, acute asthma, cystic fibrosis, pulmonary hypertension, cardiovascular disease, and certain cancers[*]. A lot of these keto side effects happen due to eating too little protein[*][*]:

Thyroid problems

Weight loss plateaus

Hormonal problems

Hair loss

Now that you know why protein matters, it’s essential to choose the best possible protein sources for your diet. When selecting keto protein sources, choose the highest quality you can reasonably afford. When you create a meal plan, be sure to refer to the keto diet food list and the ketogenic diet grocery list for ideas. If you’re an athlete who typically uses protein powder, choose a keto-friendly brand.

These are the best sources of protein on the keto diet:

Beef, preferably fattier cuts like steak, veal, roast, ground beef, and stews

Poultry, including chicken breasts, quail, duck, turkey and wild game — focus on the darker, fattier meats

Pork, including pork loin, tenderloin, chops, ham, bacon, and ground

Fish, including mackerel, tuna, salmon, trout, halibut, cod, catfish, and mahi-mahi

Shellfish, including oysters, clams, crab, mussels, and lobster

Organ meats, including heart, liver, tongue, kidney, and offal

Eggs, including deviled, fried, scrambled and boiled — use the whole egg

Lamb meat

Goat meat

Grass-fed, full-fat dairy, including grass-fed butter, heavy cream, cottage cheese, and cream cheese

Vegetarian sources, like macadamia nuts, almonds, and nut butter

Whey protein powder

How Much Protein to Eat on Keto

The Standard American Diet (SAD) 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 (or stay in) 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.

Step #1: Protein Always Comes First

The first step for successfully tracking your keto diet macros is to calculate your protein intake.

The amount will differ depending on the activity level per person.

If you’re sedentary, consume 0.8 grams of protein per pound of lean body mass at a minimum. Lean body mass is the amount of weight you carry that isn’t fat. Use a bioelectrical impedance scale, calipers, or get a DEXA scan to find your lean body mass. Then take that weight and multiply it by 0.8. This is the amount of protein you should eat every day. If you’re an athlete or looking to build muscle, consume 1-1.2 grams of protein per pound of bodyweight. This is the absolute minimum you should be eating. You can eat more if needed, and you shouldn’t worry about creating excess glucose. It’s more problematic to get less protein than it is to eat more.

Step #2: Calculate Carbohydrates

Reduce your carbohydrate intake to 20-50 grams of total carbs.

Athletes and those looking to build muscle can consume higher amounts, whereas people who live a sedentary lifestyle should try to stay under 30 grams of total carbs.

Step #3: Get the Rest of Your Calories From Fat

Once you calculate your protein and carbohydrate intake, subtract that amount from your total daily calories.

Those remaining calories should come from healthy fats.

To find the number of calories per macronutrient:

Protein = 4 calories per gram

Carbohydrates = 4 calories per gram

Fats = 9 calories per gram

Here’s an example:

Assume your goal is to eat 150 grams of protein per day and 30 grams of carbohydrates with a 2,100 daily calorie allowance.

150g protein x 4 = 600 calories

30g carbs x 4 = 120 calories

2,100 – (600 + 120) = 1,280 calories

To find your fat intake = 1,280 / 9 = 142g of fat

The macronutrient breakdown for this example comes out to:

150 grams of protein

142 grams of fat

30 grams carbohydrates

If you don’t see the results you want with the keto diet, using this approach may help you overcome any obstacles you’re experiencing. Here’s an example: Let’s assume your goal is to eat 150 grams of protein per day and 30 grams of carbohydrates with a 2,100 daily calorie allowance. 150g protein x 4 = 600 calories

30g carbohydrates x 4 = 120 calories

2,100 – (600 + 120) = 1,280 calories

To find your fat intake = 1,280 / 9 = 142g of fat The macronutrient breakdown for this example comes out to: 150 grams protein

142 grams fat

30 grams carbohydrates

Measure Results Not Ketones

If your goal is to maintain optimal energy levels and achieve a lean physique, you should not worry about continually tracking your ketone levels.

Instead, focus on long-term lean tissue growth.

Ketone production is not the only metric to track when gauging your success on the ketogenic diet. Looking at the mirror, measuring your lean body mass, and assessing your energy levels are excellent ways to determine the effectiveness of your diet because producing ketones doesn’t always mean you’re burning them for energy. When you first start the ketogenic diet, your body may be excreting excess ketones through your breath and urine. Often, these ketones aren’t being used for energy because your mitochondria haven’t adapted to processing ketones effectively. The longer you follow the keto diet, the more efficient your body becomes at using ketones as its primary fuel source. This is why many keto-adapted people will have slightly lower ketone levels (.6 – .8 mmol). Their body isn’t flushing out excess ketones — it’s using them. Building lean mass over time is a better indicator of keto success because it proves that you’re burning off your body’s fat storages for energy. The bottom line is that unless you’re following the keto diet to help with severe health conditions like cancer or Alzheimer’s disease, maintaining high ketone levels should not be a priority for you. Instead, track your overall body composition, lean tissue growth, and energy levels. Is Too Much Protein Keto-Friendly? The Idea of Too Much Protein on Keto Is a Myth Many people in the keto community mistakenly keep their protein intake low to prevent glucose production through GNG. Because of this, beginner keto dieters may never see the lasting results they hope for on the low-carb, high-fat lifestyle. The truth is that too much protein keto-style is a myth. If you hit a weight loss plateau, experience a dip in energy, or notice hormonal imbalances, increasing your protein intake can help. Instead of focusing on keto macronutrient percentages, follow the steps above or use the macro calculator to figure out your new macro intake and make your keto diet work even better for you.
