Protein Intake While Keto: Why It Matters How Much To Eat And What My Intake Looks Like Now
If you ask the average person, ketosis is primarily about carb restriction and fat intake. Go on a low-carb diet, eat more fat, allow your body to burn its own reserves. Pretty straightforward. Ketones are supposed to replace glucose.
But what do we make of protein? Some keto dieters avoid it like the plague, worried anything more than a quarter pound of animal flesh will knock them back into sugar-burning purgatory. Some have even likened it to chocolate cake. Others eat it freely. Whos right?
The most restrictive therapeutic ketogenic diets, the ones used to treat childhood intractable epilepsy, are very low proteinaround 5-10% of calories. These diets are designed to maximize ketone production. Any more protein than that and those kids might not make enough ketones to treat their condition.
The most ketogenic state of allfastingis also very low in protein. Zero, to be exact.
Okay, so protein can inhibit ketosis. Why? Whats going on?
One common assumption is that too much protein converts to glucose via gluconeogenesis. This is the steak is just chocolate cake hypothesis. It makes sense and sounds reasonable. Its also completely wrong.
This isnt a real issue.

Can Too Much Protein Get You Out Of Ketosis
So yes, too much protein can kick you out of ketosis.
Heres the kicker:
As it turns out, people who have Type 2 Diabetes are more prone to experiencing insulin spikes after eating protein. On the other hand, if youre generally healthy and your blood sugar levels stay within the normal range, you can tolerate protein better.
Theres a lot of confusion around gluconeogenesis. Eating more protein will not activate gluconeogenesis. Gluconeogenesis wont put you out of ketosis.
We also want to address a common concern with protein consumption on keto, and thats gluconeogenesis. Theres a lot of confusion around gluconeogenesis. A lot of newbie keto dieters think that gluconeogenesis is a bad thing because it interferes with ketosis. But does it really hinder ketosis?
Gluconeogenesis is a metabolic process where your body makes glucose from non-carbohydrate sources. These non-carb sources include lactate, amino acids, and glycerol 12.
This metabolic pathway is important since your brain and red blood cells depend on glucose for fuel. However, as your body produces ketones which are your alternative fuel sources, your brain can now use ketones. Thus, it saves blood glucose for your red blood cells 13.
So heres the short answer:
History Of The Keto Diet
The ketogenic diet has been around for decades, but has been surging in popularity.
Note that long-term, flexible dieting is just as good at helping your reach your weight loss and fitness goals as a keto diet.
It could be argued that flexible dieting is better as it is less restrictive and more sustainable.
However, a keto diet may be appropriate for someone looking for faster initial results¹.
- Those training for fitness competitions.
- Those trying to lose weight for an event but have a shorter time window.
- Those who have tried flexible dieting but because of metabolic issues are unable to lose weight eating normal levels of carbohydrates.

Factors Affecting The Balance Between Protein Synthesis And Breakdown
As shown in the diagram above, some of the amino acids we eat and some that come from protein breakdown are taken up by the liver, kidneys, and muscle where they are metabolized for energy and for purposes other than protein synthesis. In the process, they release the nitrogen molecules that characterize amino acids, and these are mostly excreted as waste nitrogen in the urine. In addition, some protein and protein breakdown products are lost each day from the skin and in feces, but this typically represents about 10% of daily protein losses.
In our dreams, most of us would like to be able to rapidly gain lots of muscle and lose lots of body fat. But in reality, if each morning we wake up with about the same amount of muscle as we had yesterday, we have been able keep protein synthesis and breakdown about in balance, and thatâs a good result. When it comes to changes in our protein metabolism, good things happen slowly.
The most rapid changes in protein balance occur with infection, injury, stress, and starvation/fasting. Severe infection and trauma can result in 2â3 pounds of lean tissue loss per day, while up to a pound per day can be lost in the first week of the bodyâs adaptation to fasting.
Factors known to stimulate or facilitate lean tissue gain:
- Adequate intra-cellular minerals
- Creatine supplements
- Illegal use of anabolic steroids and growth hormone
How To Get More Protein On A Keto Diet
An effective meal plan will help you reach the right amount of protein for your keto diet.
In order to ensure youre getting enough protein and more, make your protein choice at every meal and snack a priority. Make it a goal to eat at least 4-6 ounces of protein at every meal and 1-2 ounces at every snack.
Keep high protein foods that are easy to grab on hand. Foods like:
- Hard-boiled eggs
- Sliced deli meat
- Keto protein balls or bars
Meal prepping also helps ensure that you have the protein options you need. Cook 5-6 chicken breasts or steaks at the beginning of the week to serve with different meals. Cooking your protein all at once will save you time and make sure you get all your protein needs throughout the week.

How Much Protein Should I Eat Every Day
Obtaining the correct amount of protein should not be hard or complicated. Most times, all you have to do to reach your daily target range is consume a satisfying amount and be mindful of when you start to feel full.
Below are the amounts of food you have to consume to gain 20 to 25 grams of protein:
- 100 g of fish, meat, and poultry birds
- 4 big eggs
- 240 g of plain Greek yogurt
- 210 g of of cottage cheese
- 100 g of hard cheese
- 100 g of peanuts, almonds, or pumpkin seeds
- Other veggies, nuts, and seeds contain a little amount of protein, about 2 to 6 grams per serving.
Fat Percentage Of Daily Calories On Keto Diet
Finally, the amount of fat makes up the rest of your daily caloric needs. Fat will come out to be the highest macronutrient of the three , which is why the keto diet is a high fat diet.
When I was a beginner I thought I was eating a lot of fat, simply because it was way more than I was used to on a Standard American diet however, I was still not eating enough! Protein was making up way too much of my diet.
I was depending on cheese for a lot of my calories because I knew there were no carbs. Cheese is usually about 50/50 fat/protein, so this could be hurting you. This is why advanced keto dieters depend on things that up their fat content super fast, like keto coffee and fat bombs.
The fat content in the keto diet is unusually high for a person who has not been on keto before.
Fat should come from healthy sources…no soybean oil or canola oil, please! We’re talking high in omega-3’s, no trans fats, low saturated fats. No, we don’t believe saturated fat is a complete no-no, there’s going to be some in your organic meats and cheese however, this should not make up the majority of your fat.
Think coconut oil, extra virgin olive oil, organic grass-fed butter or ghee, heavy cream, avocado oil and fatty cheeses. You can even include avocados, olives and some low-carb nuts in this category. Almonds, walnuts and pecans are good low-carb nuts. Eat peanuts only in moderation.

A Mediterranean Keto Diet May Be A Heart
How It Works Think of Mediterranean keto as a combination of two popular approaches to eating: sticking to standard keto macro amounts, while emphasizing Mediterranean diet elements like fatty fish and olive oil. The main emphasis is on the quality of fats youll be eating, says Madeline McDonough, RDN, who is based in Boston. Unlike the standard keto diet, which doesnt specify which fats to prioritize, Mediterranean keto diets emphasize options like monounsaturated fatty acids, which may help lower LDL cholesterol, and omega-3s that are anti-inflammatory, she says.
Who It’s Best For This is for those who want a flexible approach to healthy eating that is sustainable long term, notes McDonough, and who want more emphasis on Mediterranean elements like nonprocessed food and high nutrient density. If youre a huge fan of salmon and sardines, this may be your favorite keto choice.
Risks to Note The standard Mediterranean diet which is not keto, thanks to its amount of whole grains and fruits has many elements that are worth shuttling into a keto plan, so the risks are minimal, says McDonough. If you want to get truly Mediterranean, incorporate social time into your meals, rest after eating, and get regular physical activity.
How Protein Helps Weight Loss
Research shows that protein tends to be satiating, helping people to feel full for longer . This aspect alone is critical for losing weight .
After all, feeling hungry is frustrating and its a key reason why people fail diets.
Protein also helps in other ways. For example, high-protein meals can lower cravings and help people to snack less . Likewise, protein increases energy used. This effect isnt dramatic but any benefit helps.
The muscle-building aspect of protein is also important. Having more muscle mass can make weight loss easier and promote calorie burning.
Having enough protein makes weight loss easier even on keto
Do You Have To Track Macros On Keto
It is possible to go into ketosis without tracking macros, but tracking macros ensures the following three things:
Transitioning From the Keto Diet
You should then transition to a normalized set of macros. While keto dieting can be good for short term fat loss, its important that it not brainwash you into thinking that certain foods or macros are bad. Eating a balanced diet with an understanding of your total daily energy expenditure is the healthiest way to eat and the most sustainable way to lose weight long term.

Protein Requirements For Weight Loss On A Ketogenic Diet
While on keto, upping your protein intake can help with weight loss as protein is the most satiating macronutrient.
A 2005 study put subjects on a weight maintenance diet that was either low in protein or high in protein . Those on the high protein diet spontaneously ate around 441 calories less with no real effort to reduce calories.
Researchers believe that the calorie reduction may be related to the impact that a high protein diet has on leptin a hormone that inhibits hunger.
Although it is understood that protein helps with weight loss, the exact amount needed to optimize weight loss is still up for debate and depends on a variety of factors.
Active people may benefit from eating between 1.8 – 2.7 grams of protein per kilogram of body weight when trying to lose weight.
For people who are sedentary and overweight, 1.2 – 1.5 g/kg may be more appropriate to promote weight loss while keeping calories under control.
If a person weighs 250 lbs, this translates to 135-170 grams of protein per day. If your goal with keto is weight loss, a focus on protein intake will make achieving that goal much more accessible.
If your main goal is weight loss, you still need to watch your calorie intake, even if the calories are coming from protein. Excess calories will lead to weight gain, no matter what the source.

How Much Protein Can You Eat And Still Remain Keto
It depends on your goals and requirements.
If youre dealing with serious epilepsy, creeping dementia, general inflammation, or anything else that requires or may improve with deep ketosis, aim for a lower protein content . Get those high ketone levels, see how it feels, and see if thats the protein intake for you. Start low, really revel in those high ketone readings.
If youre losing weight , eat closer to 15-20%. For you, the ketone readings arent the biggest focus. How you look, feel, and perform are your main concern. Eating slightly more protein will increase satiety, making eating less a spontaneous, inadvertent thing that just happens. It will also stave off at least some portion of the lean mass accretion that occurs during weight loss you want to lose body fat, not muscle.
If youre trying to gain large amounts of muscle, eat closer to 20-25%.
