Protein Sparing Modified Fasting AKA: PSMF or “Cut fat intake and up protein to break stalls” – with or without Keto Chow

This entry is part 8 of 9 in the series Keto Basics

The concept of a “Protein Sparing Modified Fast” or PSMF can sound a bit complicated at first, but it can be a fantastic way to break through a stall and cut body fat. PSMF isn’t for everyone and, depending on how you implement it, isn’t typically used for extended periods of time. You’re doing a sort of “fast” that’s designed to keep muscle protein intact (or “spare” it) while still letting your body consume stored fat for energy. The PSMF subreddit sums it up as:

PSMF is a ketogenic diet designed to jump-start a weight loss program (either for rapid fat loss for a body builder or those with some weight to lose) or break a stall. It is a modified fast and as such is not a lifestyle. The idea is basically to only eat to prevent lean muscle loss (protein).

The Basics of PSMF

With a typical Ketogenic diet you will be getting 20-50g of carbohydrates as an upper limit, with anywhere from 90-160g of protein (depending on goals, activity, and other factors), with fat as a variable that can come from the food you consume or from your body’s fat storage. For the rest of this article, I’m going to be using numbers from Maria Emmerich’s Macro Calculator. I’m setting the calculator to give numbers for a 220 lb, 40-year-old female with 35% body fat that we will call “Jane”; YOUR numbers will be different so please make sure you pull up the page and enter in YOUR measurements. The Calculator says that if Jane wants to lose weight quickly, she should use 2 different calorie/fat/protein/carb combinations (click to embiggen!):

PSMF Calculator Results for Jane

If Jane had selected regular “Fat Loss” instead of PSMF, it would have told her to do 1659 calories with 118g of fat, 130g protein, and 20 total carbs. There are a few important points that I would like to cover here:

  1. You will notice that we are ALWAYS talking about grams of stuff, we are not using percentages for the fat/protein/carbs. Macro percentages are ONLY used for treating epilepsy and even then it’s more properly done with a 4:1 or other ratios of fat calories to other calories instead of percentages. If you’re looking at a “Keto Macro Calculator” that uses percentages it isn’t going to be useful, that’s why we consistently recommend Maria’s calculator over all others.
  2. If you have looked at other “Keto Macro” calculators, you may notice that the amount of protein recommended is WAY higher. Craig Emmerich covers a lot of the old fear that people used to have about protein and why it’s unfounded in his presentations about PSMF given at Keto Salt Lake 2021 – I highly recommend checking it out.
  3. The text above the figures reminds you that protein in a MINIMUM, get at least that much and you can go over if you stay below the calories (by getting less fat).
  4. Right there in the calculator results, it explains the basic setup of how to do PSMF “Add 1-3 days a week of PSMF to speed up fat loss or break stalls. Then Fast Fat Loss macros above on the other days. If doing this two or more weeks in a row, add an overfeeding day each week with 400-600 additional calories of protein and fat.
  5. Maria recommends you stay under 10g of TOTAL carbs. You will quickly find that 10g of total carbs and 30g of total fat will necessitate a major change in how you eat on your PSMF days (hello chicken breast!).

Lemon Meringe Nutrition PanelHow you can use Keto Chow for PSMF

OK, we’ve covered some of what PSMF is and how to do it. How can you use Keto Chow as a tool to help you be successful with PSMF? First things first: we need to address the TOTAL carbs situation.

Most flavors of Keto Chow contain around 7.6g of total carbohydrates. If you wanted to use 3 meals of Keto Chow on your PSMF days, that would be 22.8g of total carbs before you even add any other food and 22.8 is more than 10! Here’s the thing about the total carbs in Keto Chow: 5.71g of that is acacia and xanthan gum fiber (mostly acacia). Acacia gum is some REALLY cool stuff, especially for a keto diet. There’s a long explanation of the benefits of acacia gum on keto on this page, but the short version is: your body can’t digest acacia gum, but your gut bacteria DOES and it turns the former carbohydrate into short-chain fats. Carbs in -> turned into fats = happy gut biome with energy for your intestinal cells. All of this is why I, personally, do not count acacia gum (or xanthan gum) towards my total carbohydrate limit. With that acacia and xanthan gum quantity removed, the result is 1.8g of fiber and lactose carbohydrates – let’s call it 2g just for fun. 6g of carbs from 3 meals of Keto Chow still leaves me with 4g and that’ll be taken up by the incidental carbs in mostly meat that I’m eating to cover the rest of my protein goal after 3x Keto Chow meals made with 10g of butter each.

Enough about me, let’s go back to Jane and her goals! Jane needs to get 159g of protein, under 30g of fat. For Jane, that means 78.6g of protein from 3 meals of Keto Chow (or 52.4g if she uses 2 meals of Keto Chow – the number of meals of Keto Chow is entirely up to you!). Jane will be 80g of protein short doing 3x Keto Chow, but she knows that she got a full 100% of her vitamins and minerals because of the Keto Chow. How can Jane get that additional 80g?

It’s time for Cron-o-meter!

We love Cron-o-Meter around here! More info here about using Cron-o-meter to track your net carbs. The key difference between Cron-o-Meter and most other tracking programs like MyFitnessPal and Carb Manager is the Cron-o-Meter uses a curated database. That means every entry you find has been verified to be correct. I switched from MyFitnessPal after I tried entering butter into my tracking and there were 7 different entries that were wrong, one even said “butter (net carbs)” butter has 0.01g of total carbs per tablespoon, it doesn’t need a “net carbs” entry! Anyhow, the intricacies of Cron-o-Meter are beyond this particular blog post, but Jane took the numbers from Maria’s calculator and put them into Cron-o-Meter as custom targets:

Macro Targets in Cronometer

Jane goes ahead and enters the food she’s planning to eat that day. In this case, it’s 3 different flavors of Keto Chow, along with the 10g of butter that she’s having in each meal to make sure that she will be able to absorb the fat-soluble vitamins in the meals:

Food and Targets 1-Cronometer

Wait a minute: the fat is a little high when she uses 10g of butter in each shake! 10g of butter has 8.1g of fat and each of the skinless chicken breasts also 6.1g of fat. Let’s change the amount of butter in each Keto Chow to 7g. That will make for 21g of butter in total. Jane still wants to get around 10g of fat per meal so she can either have a chicken breast as part of 2 meals, or actually split up the 2 pieces of meat into 3 portions and have 2/3 of a breast with each meal. Check out Jane’s targets NOW!

Food and Targets 2That looks REALLY good. Jane is half a gram over on fat and 3g over on protein, but both are exceptionally close to her targets. For her non-PSMF days, Jane could take the approach of maybe doing 2 Keto Chow and having some beef for her 3rd meal. In fact: Jane decides to go to have 2 of the same 7g of butter Keto Chow shakes she had the previous day and then she’s going to go to Texas Roadhouse and get a 12oz Prime Rib along with a side salad.

Food and Targets 3Honestly, that’s phenomenal. Jane has a good plan in place! Additional PSMF Resources:

8 Things to Know Before Starting Keto

This entry is part 1 of 9 in the series Keto Basics

You’ve watched a bunch of videos, listened to some podcasts, lurked on a few forums, and you’ve decided you’re gonna do it: you’re gonna try this keto thing. Great! Come on in, the water’s fine! And guess what? It’s as simple as cutting sugar and starch out of your diet and keeping all other carbohydrates to a minimum. Do that, and congratulations—you’re doing keto!

But wait a minute…

Not so fast.

While it’s true that all you really need to do to get started is to eliminate the majority of carbohydrates from your diet, there are a few things to be aware of before you jump into this. Let’s take a look at what you need to know before starting keto.

  1. Make sure you understand what keto really is.

Contrary to what you might see on social media, keto isn’t about adding butter and coconut oil to everything you eat, and it’s not about eating piles of bacon covered with bacon, with a bit of bacon on the side. (Not that there’s anything wrong with that bacon part!) Rather than “keto,” think of this way of eating as very-low-carb. When you frame it that way, you put the emphasis where it belongs: on keeping your carbohydrate intake very low. This is the single most important part of a ketogenic diet. What makes a diet “keto” is not the presence of mountains of fat and oil, but the absence of the carbs.

You don’t need any special gadgets or gizmos to be successful on keto. This is a way of eating, not an erector set for a Mars excavator robot. You might’ve seen videos of people checking their blood sugar or ketone levels with special meters, and pictures of people’s kitchen counters decked out with bottles of MCT oil, keto bone broth protein powder, and keto coffee creamers. If you’re a data lover—and you have a couple of thousand extra dollars floating around—you’re welcome to use these kinds of things. But if you want to keep things low-tech and simple, know this: keto is about one thing: keeping your carbohydrate intake very low.

Your body isn’t a computer. You don’t have to have a Ph.D. in math to figure out your “macros” or how many calories you should be eating. Keto doesn’t work by magical percentages of fat, protein, and carbs in your diet. You don’t need to calculate your diet down to the last microgram so that you “hit your fat macro” or “don’t eat too much protein.” What you need to do is keep your carbohydrate intake very low. Period.

  1. Have realistic expectations.

Keto is a very powerful way of eating that can radically transform your health and physique. But keep in mind that your transformation might not be as fast as you’d like it to be. Don’t compare your results to anyone else’s. We are all unique individuals, with our own genetics, dietary and medical histories, and lifestyle habits. Use other people’s successes as motivation and inspiration, but don’t “compare and despair.” Start where you are, and follow your own path. If you do the right things, you’ll get to your goals; the journey might just take a little longer than you wish it would.

If you’re specifically in this for fat loss, heed these words and save yourself a mountain of frustration and disappointment: women, don’t compare your rate of fat loss to a man’s. Men tend to lose weight more quickly on keto, even when they’re not as strict with the diet. It’s unfair, it’s infuriating, but it’s just the way it is. You can’t fight biology. Your fat loss will come; it’ll just come more slowly than it does for the men in your life. And older folks, don’t compare your fat loss to that of someone younger. There are always exceptions, but as a general rule, younger people lose fat more quickly than older people. Younger people have faster metabolisms. You can envy them that, but look on the bright side: you probably have more than ten dollars in your checking account.

Another note about fat loss: the more you’re looking to lose, the more quickly it’ll come off—at first. If you have a substantial amount of weight to lose, a good rate of loss is about 1-2 pounds per week. People who have less to lose will probably lose more slowly. If you’re new to this way of eating, you might lose several pounds in the first week or two but then things will slow down. This is normal and to be expected, so be ready for it. If you find things going slower a few weeks into keto, don’t worry that you’re doing something wrong.

Whatever you’re looking to achieve with keto—fat loss, relief from migraines, more energy, clearer skin, lower blood sugar—some of it might happen right away, but other things will take longer. Play the long game and be patient. Be on the lookout for beneficial things keto is doing for you even if you haven’t gotten to your main goal. (See point 8).

  1. Be prepared for keto flu.

Ah yes, the dreaded “keto flu.” The truth is, most people make the transition to keto with no problems. But some people experience a few hiccups as their body adjusts to life without sugar and starch, so it’s important for you to know about these in case they happen to you. The first thing to know is, these issues will be mild and temporary. They’ll pass quickly and they’re a small price to pay to feeling great and experiencing all the benefits of keto once your body adapts.

The most common issue is headaches. You may also feel dizzy, lightheaded, nauseated, or fatigued. Most of these can be prevented by taking in more salt. As I mentioned in a previous article, ketogenic diets increase your body’s need for sodium. Skimping on salt is usually the cause of headaches, lightheadedness, and feeling sluggish on keto. Be generous with salt and sodium in your diet: either sprinkle it liberally on your foods or add it to your beverages, or be sure to incorporate salty foods into your diet—things like bacon, olives, pickles, or pepperoni. Not a fan of those? Make a cup of broth using a bouillon cube for an easy sodium boost.

If you experience muscle cramps (especially in the legs) that you can’t attribute to overexertion, extra magnesium usually helps. Magnesium also helps with constipation, which some people experience on keto. If sodium alone doesn’t help with headaches, add magnesium; it’s helpful for headaches, too. (Check out the electrolytes from Keto Chow for convenient ways to get sodium and other important minerals.)

  1. Get professional guidance on medication.

If you take medication for diabetes (either type 1 or type 2) or for high blood pressure, you must have medical supervision when you start keto. This is not negotiable! Ketogenic diets are so powerful for normalizing blood sugar and blood pressure that you may need to adjust your medication doses with days of starting. For people with type 2 diabetes, insulin injections sometimes need to be stopped on the first day of starting the diet.1 (And people with type 1 might need to adjust their dose on day one.) If you take the same amount of medication you needed when you were eating a high-carb diet, but now you’re on a very low-carb diet, you might end up overmedicated, and this comes with effects ranging from dizziness and fatigue to more dangerous things, such as passing out.

Don’t adjust medication on your own. Work with a physician or other qualified medical professional who can advise you on changing your medication safely, as needed.

  1. Get baseline blood tests.

You don’t have to have any blood tests done before starting keto, but I recommend it—you’ll want to have something to compare to after a few months so you can see how much things have improved! Your body will give you loud and clear signals about how keto’s working for you—more energy, less joint pain, no more brain fog or heartburn—but it can be rewarding to also see objective proof that eating delicious food has had a positive impact on your health. Plus, if weight loss is a bit slow or you’re not getting closer to another goal you have, seeing certain measurements go in a favorable direction can help keep you motivated to stay on plan.

For a good baseline before starting, I recommend a comprehensive metabolic panel (CMP, which includes fasting glucose and liver enzymes), complete blood count (CBC), hemoglobin A1c, fasting insulin, C-reactive protein (CRP), and a lipid panel (cholesterol & triglycerides). Most of these are pretty standard tests, but you might have to specifically request fasting insulin. It’s not a routine test, but it’s important. For the lipid panel, ask your doctor if they can order a particle size test. (This isn’t essential, but it’s nice to have if you can get it.) If you suspect you might have a thyroid problem, ask for a comprehensive thyroid panel. (It’s important to ask for a comprehensive panel. If you ask for a “thyroid test,” many doctors test just one or two things, but a comprehensive panel provides much more information about thyroid function. See here for details.) If you’ve been taking antacid medication for a while—either by prescription or over-the-counter—consider asking for a vitamin B12 test. Antacids interfere with the absorption of vitamin B12, which is critical for energy levels and healthy neurological and cognitive function.

  1. Know how to order in restaurants.

In an ideal world, everyone would cook all their meals at home from scratch. But over here in the real world, where you and I live, dining out is one of life’s small pleasures. Whether you do it because you don’t like to cook, because it’s convenient, or because it’s a kind of treat and doesn’t have to cost a fortune, chances are you’ll find yourself in a sit-down restaurant or at a fast food drive-thru sometime after starting keto. Now that bread, pasta, rice, potatoes, beans, and noodles are off-limits, what can you order?!

Dining out or grabbing food on the go is easy. Just ask to swap out starchy sides in favor of non-starchy vegetables or a salad. Most restaurants will have no problem substituting steamed broccoli or roasted brussels sprouts for a baked potato or scoop of rice. At fast food places, bun-less burgers or grilled chicken are good ways to go. (Pro tip: ask for burger patties or grilled chicken patties a la carte if you don’t want the lettuce, tomato, and other toppings. It’s cheaper to just get the meat.) Tex-Mex places will serve you meat, veggies, and cheese in a lettuce bowl instead of wrapped in a tortilla. Just skip the rice and beans.

If you’re on the road and need to grab something quick from a convenience store, you’ll have no problem finding suitable items. With string cheese, nuts, pork rinds, pepperoni, and low-sugar beef jerky, there’s practically a smorgasbord of keto-friendly foods at these places now. If you’re passing by a grocery store, it’s even easier: grab some deli counter lunchmeat, a rotisserie chicken, canned fish (with a pop-top for easy opening), and/or pre-cut vegetables from the produce department. Many supermarkets have fresh salad bars now. These are perfect for a quick keto meal: lettuce, spinach, bell peppers, cucumber, radishes, mushrooms, turkey, ham, hard-boiled egg, shredded cheese. Being in a hurry or being on the road doesn’t mean you have to sacrifice your low-carb ways. (See here for more tips on staying keto while dining out.)

  1. Go easy on yourself.

Some people sail right through transitioning to keto. What? I can eat ribeye steaks, macadamia nuts, and Gruyere cheese and lose weight? Where do I sign?! But for others, this way of eating is a struggle to get used to. When you’ve spent your entire life eating cereal, granola, bread, pasta, rice, potatoes, ice cream, fruit smoothies, and other sweet and starchy things, it can be difficult to let go of them.

When you think about it, keto really isn’t that big a deal. It’s just no sugar or starch. Other than that, you’re eating the same meat, poultry, seafood, eggs, dairy, and low-carb vegetables you’ve always eaten. However, for some people, this is a really big deal! Be patient with yourself if you don’t master keto right away. (I sure didn’t!) Do the best you can, and if you find yourself faceplanting into a cupcake six days in, make sure you faceplant into just one cupcake, and not the whole box. Get back on the plan right at your next meal. Not tomorrow, not Monday, but immediately.

If you have trouble sticking to keto, it’s okay to ease into it gradually, rather than giving up carbs cold-turkey. The best way to experience the full effect of keto is to do it full-on right from the start, but if that all-or-nothing mindset has tripped you up in the past, then make a slower transition to this way of eating. A good way to approach this is to eliminate one high-carb food category each week. For example, week one: no fruit. You can still have bread, pasta, rice, beans, etc., just no fruit. Week two: no fruit and no pasta. You can still have bread, rice, beans, potatoes, etc., just no fruit or pasta. Each week (or even every two weeks), remove a high-carb food from your diet, and eventually, you’ll be on keto. It’ll take you longer to get there this way, but if doing it slowly helps you actually do it, that’s all that matters. Better to make a gradual transition and stay with it than to jump in overnight but have to restart every two weeks.

  1. Give yourself non-weight milestones.

Weight loss is just one of many reasons people adopt a keto diet, but since it’s probably the most common one, here’s something to keep in mind if you’re doing keto to lose weight. Look beyond the scale to assess whether keto is doing anything good for you. A lower body weight is only one thing on a long list of what keto can help you achieve. Looking for positive effects unrelated to your weight can keep you motivated to stay on plan if a weight loss stall or plateau has you feeling frustrated. Do you have brain fog? Acne? Acid reflux? What about migraines, hypoglycemia, hypertension, or low energy? Keto is good for all of these, and more. Research shows that metabolic health can improve substantially—including metabolic syndrome being reversed—even when you don’t lose a significant amount of weight.2,3 Here’s a list of 14 ways to tell if keto is working for you besides weight loss.

So, yes, if you want to start keto right now, all you have to do is stop eating sugar and starch. But keeping these 8 points in mind will set you up for success and give you a boost if your enthusiasm for this way of eating starts to wane in the early days. In a future article, I’ll give you some real-world strategies for making keto simpler and easier to stick with for the long term.

New Video: What is “Keto”?

This entry is part [part not set] of 2 in the series Keto Chow Information Videos

What is “Keto” or a Ketogenic Diet, how do you do it? Miriam and Chris from Keto Chow sit down to talk about how to do a well-formulated ketogenic diet and set yourself up for success.

We have several other videos you should check out:

Here are Chris’ suggestions for calculating your macros:

Carbs are an upper limit, meaning do not go higher than that. You want to be as far below them as possible, approaching zero if you can.

You want to hit your protein goal. If you go over it, that’s not a big deal. There’s a thing in your body that can turn protein into glucose but it’s DEMAND driven, not supply-driven, and so long as you’re keeping your carbohydrates low, your insulin will be low as well and too much protein isn’t something to be concerned about. Too little protein is a problem. A lot of people argue about this but Dr. Benjamin Bikman settled the debate back in 2018:

Fat is more variable. If your insulin is low then your body will be able to supply fat using your body’s reserves (yay!). If you are just starting keto then your insulin is likely high enough that the fat is locked away and you will not be able to access it readily. Here’s the rub: you’re not eating carbs so you don’t have glucose; but you also can’t access stored fat so unless there’s sufficient fat on your plate, your cells will not have any sources of energy and you’re going to get hungry. Probably REALLY hungry and think this keto thing is a pack of lies. The solution is to make sure you are getting sufficient fat until your body figures out what it’s doing and can pull from storage. Especially when you’re starting up the amount of fat you’re eating. Throw some extra butter on your steak, add some more heavy cream to your diet root beer, etc… After you’ve adjusted, then you can start running a caloric deficit but you’re probably not even going to need to deliberately do it since your body should clue-in and tell you “nah, I’m full – save that for later”

Finally: this cannot be emphasized enough: get salt. Like: a lot of salt. Not to be melodramatic but everything you’ve been told about limiting salt consumption is dead wrong and has no application to a ketogenic diet with low insulin levels. Salt your food. Salt your drinks. Eat some pickles. Drink some pickle juice. Make some chicken broth. Add more salt to your food. Failure to get enough salt will result in you feeling like crap and getting “Keto Flu” – I can speak from experience.
