However are “PSMF” diets actually as efficient as some declare?
Or are they simply one other gimmick that overpromises and underdelivers?
On this article, you’ll be taught what a PSMF-style weight loss program is, the right way to do it accurately, and whether or not it’s the precise alternative for you.
Key Takeaways
- A protein sparing modified quick (PSMF) is a crash weight loss program that includes consuming principally lean protein and a few fibrous greens to lose fats shortly whereas minimizing muscle loss.
- On a PSMF-style weight loss program, you may lose 2-to-8 kilos of fats per week, relying in your physique fats share, exercise ranges, and calorie consumption.

What Is a Protein Sparing Modified Quick?
A “protein sparing modified quick” (PSMF) is a weight loss program that includes excessive calorie restriction and consuming kind of nothing however very lean protein and low-calorie, fibrous greens.
Usually, energy will likely be restricted to round 15-to-30% of what you’d have to eat to keep up your weight (your TDEE). For instance, when you usually eat 2,500 energy, you’d eat 375-to-750 energy whereas following a PSMF weight loss program.
Nearly all of these energy want to return from lean protein, too.
Because of this a PSMF is known as “protein sparing.” By offering enough dietary protein, you may “spare” muscle protein from being damaged down for vitality.
In different phrases, you’re modifying a whole quick (the place you eat no energy) by including simply sufficient protein to keep away from dropping muscle.
Protein sparing modified quicks have been utilized in research and weight reduction clinics to assist morbidly overweight individuals shed extra pounds as quick as doable for years, however they have been first codified and promoted by author, researcher, and coach, Lyle McDonald in his e book, The Fast Fats Loss Handbook.
Lyle’s PSMF suggestions have grow to be kind of the usual, and far of the knowledge on this article is from his e book.
What Can You Eat on a Protein Sparing Modified Quick Weight loss plan Plan?
As we’ve already seen, most of your energy are on PSMF-style weight loss program will come from lean proteins, like skinless, boneless hen breast, lean cuts of beef like london broil or sirloin steak, or low-to-no-fat seafood like tilapia, shrimp, crab, tuna, and cod.
You’re allowed to eat small quantities of low-calorie fibrous greens like zucchini, squash, broccoli, leafy greens, and inexperienced beans, however not more than 100 calories-worth or so per day.
Because you’re solely following this weight loss program for a number of days to 2 weeks, you could possibly survive simply tremendous with out consuming any greens. That stated, consuming small parts of low-calorie greens offers you one thing to chew on, improves your digestion, and helps you keep full.
Lastly, you’re allowed small quantities of low-calorie condiments like scorching sauce, lemon juice, soy sauce, and so forth.
What Meals Should You Keep away from on a Protein Sparing Modified Quick Weight loss plan Plan?
Right here’s what you’re not allowed to eat on a PSMF weight loss program:
- Excessive-calorie or high-carb greens or different vegetation like corn, peas, tomatoes, bell peppers, carrots, beans, potatoes, and the like.
- Fruit of any form.
- Dairy, besides whey or casein isolate, or one other low-or-no-fat-or-carb dairy protein complement.
- Nuts, seeds, or chocolate.
- Juice or different calorie-containing drinks.
- Excessive-calorie sauces like teriyaki, barbecue, or sesame sauce.
- Grains, cereals, or different high-carb meals.
- Any type of quick meals or sweets.
- Added oils of any form.
As you may see, that is an especially restrictive, low-calorie, crash weight loss program. You don’t get cheat meals or days, and also you’re solely consuming sufficient to keep away from dropping muscle (and your sanity).
How Ought to You Train on a PMSF-Model Weight loss plan?
When it comes to train, it’s usually really helpful you do not more than 2-to-3 weightlifting exercises per week. You gained’t have the vitality to get better from rather more than a handful of 30-to-60 minute exercises, and also you solely have to do a number of units of compound workouts to keep your muscle when reducing.
Exercising greater than this can be counterproductive by rising your fatigue and starvation, making the weight loss program more durable to stay to.
Is a Protein Sparing Modified Quick Weight loss plan Ever a Good Thought?
As Lyle is the preeminent authority on protein sparing modified fasting, I’ll let him reply this query:
“I’d like to reside in a world the place no person crash dieted, the place all people adopted sane and secure weight-reduction plan methods and caught with it in the long run till they reached their purpose after which caught with these newfound consuming habits within the long-term.
“I additionally need a pony and to be six ft tall and to be an astronaut. And the way about an finish to world starvation whereas I’m at it. My level? When idealism and actuality slam collectively it’s by no means fairly. Persons are going to crash weight loss program it doesn’t matter what I or anyone else inform them.”
I wholeheartedly agree.
Ideally, nobody would crash weight loss program—which is basically what a protein sparing modified quick is. You’d cease studying this text, and browse this one as an alternative:
The Full Information to Safely and Healthily Shedding Weight Quick
Nonetheless right here?
If that’s the case, then you may rely your self as a part of the bulk who is aware of crash weight-reduction plan isn’t preferrred, however nonetheless feels the professionals outweigh the cons.
In case you’re going to crash weight loss program, although, you have to do it accurately.
Whether or not or not crash weight-reduction plan is dangerous for you principally boils all the way down to how you employ it.
Technically, there’s nothing unhealthy about severely limiting your calorie consumption for temporary durations of time to hurry up fats loss.
The issue with crash weight-reduction plan, although, is individuals use it as a long-term weight reduction technique, as an alternative of a short-term measure to maneuver the needle somewhat quicker.
Individuals let themselves get obese till they attain some extent the place they’re totally disgusted with themselves. Then, they determine to take drastic motion, losing a few pounds “as soon as and for all” by ravenous themselves for a number of weeks.
They slash their energy, typically consuming far too little protein and dropping muscle within the course of. They maintain this up till they will’t stand it anymore.
They quickly fall again into the identical habits that made them obese within the first place, they usually achieve weight till they’re prepared to start out the cycle anew.
That is the worst solution to shed extra pounds.
It’s a traditional case of yo-yo weight-reduction plan, and it’s one of many causes most individuals by no means handle to get the physique they need.
In case you’re one among these perennial dieter sorts, crash weight-reduction plan isn’t for you. As a substitute, it’s best to decide to a long-term weight reduction plan that helps you shed extra pounds persistently and shortly with as little effort and discomfort as doable.
Now, when you don’t have a historical past of yo-yo weight-reduction plan, there are a number of sturdy arguments in favor of a crash weight loss program like protein sparing modified fasting:
1. You see outcomes FAST.
The largest advantage of a PSMF-style weight loss program is that you simply get to see modifications on the dimensions and within the mirror a lot quicker than you’ll with conventional weight reduction diets.
Whereas many nutritionists, coaches, and health gurus declare quick weight reduction is at all times dangerous, many research present individuals who lose essentially the most weight at the start of a weight loss program lose essentially the most weight general and maintain it off the longest.
The perfect motivation to stay to your weight loss program is quick outcomes, and that’s what you’ll get with PSMF.
Once more, this isn’t a long-term weight reduction answer, nevertheless it’s an efficient solution to kickstart your weight loss program earlier than transitioning to a extra sustainable method.
2. You don’t must spend as a lot time losing a few pounds.
The worst half about reducing is being constant day in and day trip.
In actual fact, many individuals discover that sustaining a reasonable calorie deficit is simply as annoying as sustaining a big calorie deficit, and the earlier they will get again to consuming at upkeep, the higher.
And PSMF helps you do precisely that.
3. You may get again to gaining muscle and energy quicker.
Whenever you’re reducing, you in all probability aren’t going to achieve a lot muscle or energy to talk of it doesn’t matter what type of energy coaching program you comply with.
(There are a number of exceptions to this rule, nevertheless it’s true most often).
So, when you can’t make any energy or muscle positive factors, you may as properly maximize the one type of progress you may obtain when reducing: fats loss.
In different phrases, the earlier you attain your fats loss purpose, the earlier you may get again to the enjoyable a part of getting match: lean bulking.
How A lot Fats Can You Lose on a Protein Sparing Modified Quick?
In case you’re solely limiting your calorie consumption, you may lose 2-to-4 kilos of pure fats in per week of following a protein sparing modified quick.
In case you’re limiting your calorie consumption and doing a lot of cardio, you may lose as much as 6-to-8 kilos of pure fats in per week.
For comparability’s sake, most individuals advocate you purpose for a few pound of weight reduction per week. Which means that with a PSMF, you may lose fats eight occasions quicker than you could possibly with a traditional fats loss weight loss program.
Earlier than you get too excited, although, you have to meet these standards to anticipate these sorts of outcomes:
- You have to have a physique fats share over 15%. The extra obese you might be, the better will probably be to lose fats shortly. The leaner you might be, the slower you have to lose fats to keep away from dropping muscle.
- You have to comply with the weight loss program precisely as prescribed, with no deviations, cheat meals, or errors.
- You have to do a ridiculous quantity of cardio if you wish to lose 6-to-8 kilos of fats in per week—way over you’d ever wish to do for any size of time.
Now, when you’re skeptical of the numbers I simply shared, I perceive.
Many unscrupulous entrepreneurs have feathered their nests by promising their detox tea, crash weight loss program, or unusual elimination weight loss program will assist you lose “10 kilos of fats in per week” or different such nonsense.
How will you belief I’m telling the reality?
Nicely, I received these numbers from a number of scientific research on protein sparing modified fasting.
Essentially the most excessive instance of the consequences of PSMF comes from a research performed by scientists on the College of Las Palmas de Gran Canaria.
On this research, the researchers cut up 15 obese 18-to-55-year-old males into two teams:
- Group one comply with a weight loss program that offered 10% of their TDEE, all within the type of whey protein (round 300 energy per day)
- Group two did the identical factor besides they received all of their energy from desk sugar.
Each teams adopted their respective diets for 4 days, after which switched again to a traditional combined weight loss program that offered sufficient energy for them to keep up their weight for 3 days.
When it comes to train, each teams have been pressured to stroll on a treadmill for 8 hours (20 miles) per day, adopted by 45 minutes of an arm cranking train as a type of higher physique train.
The researchers ready everybody’s meals and noticed each exercise at some point of the research. Additionally they put the entire contributors by way of numerous bodily and blood exams, inspecting every part from their physique fats share to VO2 Max to insulin ranges.
All advised, the weight loss program and train routine pressured each teams to keep up a 5,000 calorie deficit per day—sufficient to theoretically lose about 1.5 kilos of fats per day.
And on this case, that’s mainly what occurred.
After 4 days, each teams misplaced 4.4 kilos of pure fats, or simply over a pound of fats per day. Unusually, they misplaced one other 1.5 kilos of fats over the subsequent three days regardless of consuming near upkeep energy.
The researchers aren’t positive why they saved losing a few pounds over the next three days, nevertheless it could possibly be that they underestimated the variety of energy they wanted to eat to keep up their weight.
In any case, that’s a complete fats lack of 5.9 kilos in 7 days.
In the event that they’d adopted their excessive weight loss program and coaching routine for the entire 7 days as an alternative of simply 4, they might have misplaced nearer to eight kilos of pure fats.
Additionally they misplaced 6.6 kilos of complete lean mass, however most of this was water weight. After rehydrating after the intense calorie restriction, the researchers discovered they solely misplaced one pound of precise lean physique mass (muscle).
Take into accout these individuals additionally didn’t elevate weights, which might have considerably decreased muscle loss.
Additionally take into account that though group one technically was following a protein sparing modified quick, their protein consumption was decrease than most analysis would recommend is perfect for sustaining muscle. In the event that they’d eaten extra protein, they in all probability would have misplaced much less muscle than they did on this research.
Now, you’re in all probability considering these individuals have been bodily, mentally, and emotionally damaged after this ordeal, however that’s not the case.
All of them reported feeling drained, beat up, and hungry after 4 days of their weight loss program and coaching plan, however none of them received injured, overtrained, or put themselves in “hunger mode.”
Now, keep in mind that all of those individuals have been obese, with a physique fats share of 20-to-40% and a BMI properly north of 25. This makes it a lot simpler to lose fats shortly. If these individuals have been leaner, they doubtless would have misplaced much less fats and extra muscle.
That is essentially the most excessive instance of protein sparing modified fasting I do know of, however the outcomes have been replicated in comparable research.
For instance, a research performed by scientists at West Virginia College discovered that untrained, obese individuals lifting weights and consuming 800 energy per day (with solely 80 grams of protein) misplaced 32 kilos of fats in 12 weeks, and retained just about all of their muscle.
And at last, a 2016 research performed by researchers on the Cleveland Clinic Basis discovered that overweight youngsters placed on a PSMF that offered 800 energy per day misplaced 25 kilos in 12 weeks.
On this case the meals weren’t fully managed by the researchers, so it’s doubtless the youngsters have been dishonest on their diets. Nonetheless, they misplaced twice as a lot weight as the usual “one pound per week” suggestion.
Is a Protein Sparing Modified Quick Proper for You?
Not everybody is an efficient candidate for a protein sparing modified quick, however for sure individuals, it may be an efficient solution to lose fats shortly.
Right here’s the right way to determine if it’s best for you.
Physique Fats Share
In case your physique fats share is over 15% (males) or 25% (ladies), you may take into account making an attempt a PSMF.
At this physique fats share you may anticipate to simply, shortly, and effectively lose fats a lot quicker than somebody who’s lower than 15/25% physique fats. In case you’re below 15/25% physique fats, although, the danger of dropping muscle is far increased when following a PSMF.
After Overeating
Top-of-the-line makes use of of a PSMF is harm management after a interval of overeating. For instance, some individuals prefer to gorge themselves over the vacations, and use a PSMF for per week or two afterward to assist strip off among the fats they’ve gained.
I don’t advocate this, after all, nevertheless it does work.
Beginning a Fats-Loss Weight loss plan
In case you’re going to strive a PSMF, it’s greatest to do it at the start of a fats loss weight loss program when weight reduction is less complicated than on the finish of a reducing part. That is additionally a great way to spice up your motivation earlier than transitioning to a extra sustainable fats loss weight loss program.
I by no means advocate you do a PSMF on the finish of a lower, as that is when persons are most weak to burnout, bingeing, and blowing their weight loss program earlier than reaching their purpose weight—issues that may solely be amplified on a PSMF-style weight loss program.
Even when you do a PSMF at the start of a lower, I nonetheless advocate you solely strive it when you’re over 15% physique fats.
When to Keep away from a Protein Sparing Modified Quick
Whereas a PSMF-style weight loss program might be an efficient instrument for fast fats loss, it’s not appropriate for everybody. If any of the next apply to you, it’s greatest to decide on a extra sustainable method to weight reduction.
Individuals Who Struggled with Yo-Yo Weight-reduction plan or Consuming Issues
When you have a historical past of yo-yo weight-reduction plan, consuming issues, or binge consuming, don’t strive a PSMF.
As a substitute, shed extra pounds utilizing a mix of a well-designed weight reduction meal plan and intuitive consuming rules.
Athletes Reducing Weight Earlier than a Competitors
One group of outliers who could wish to strive a PSMF are athletes who have to make weight earlier than a contest.
If you end up within the state of affairs of needing to lose 2-to-4 kilos of fats within the week or two earlier than your competitors, although, then you definately’ve already made a serious mistake, and also you’re in all probability higher off suspending the competitors and making an attempt once more subsequent time.
If that’s not doable, although, then you may strive a PSMF and see how issues play out.
Learn how to Do a Protein Sparing Modified Quick
In case you nonetheless wish to do a protein sparing modified quick, there are 5 issues you have to do:
- Eat 1-to-2 grams of protein per pound of lean physique mass.
- Eat some low-calorie greens.
- Take the precise dietary supplements.
- Elevate weights not more than 2-to-3 occasions per week.
- Do some cardio.
1. Eat 1-to-2 grams of protein per pound of lean physique mass.
The purpose of a protein sparing modified quick weight loss program is to supply simply sufficient protein to stop muscle loss, and no extra.
Thus, it’s essential to scale your protein consumption primarily based in your physique’s wants.
One of many major variables that will increase your physique’s protein wants is lean physique mass, which constitutes the entire elements of your physique that aren’t fats, together with muscle, bones, and organs. The extra lean physique mass you might have, the extra protein you’ll have to eat to keep away from dropping it.
Ladies usually have extra physique fats and fewer lean physique mass than males, in order that they’ll sometimes want much less protein.
Weightlifting is one other issue that may improve your physique’s demand for protein. In case you elevate weights, you’ll doubtless profit from consuming extra protein than when you don’t.
In case you don’t elevate weights, properly, it’s best to. Other than consuming sufficient protein, lifting weights is the only greatest solution to keep away from dropping muscle whereas reducing energy.
With that out of the way in which, let’s work out how a lot protein it’s best to eat.
First, you’ll have to estimate your physique fats share and lean physique mass.
Learn this text to try this:
Learn how to Calculate Physique Fats Share
Subsequent, use the next tips tailored from The Fast Fats Loss Handbook to search out which class you fall into.
Learn how to Set Your Protein Consumption on a Protein Sparing Modified Quick
- In case your physique fats share is 15% or decrease (males) or 25% or decrease (ladies): Eat 2 grams of protein per pound of lean physique mass (LBM).
- In case your physique fats share is 16-to-25% (males) or 26-to-35% (ladies): Eat 1.5 grams of protein per pound of LBM.
- In case your physique fats share is 26% or increased (males) or 36% or increased (ladies): Eat 1 gram of protein per pound of LBM.
* In case you’re below 15% (males) or 25% (ladies) physique fats, your danger of dropping muscle whereas following a protein sparing modified quick is far increased.
For instance, let’s say you’re a 200-pound man with 20% physique fats, right here’s the way you’d discover your lean physique mass:
First, discover what share of your physique is lean mass by subtracting your physique fats share from 100.
100 – 20 = 80% lean mass.
Convert this to a decimal:
80% = 0.8
Multiply your physique weight by the end result to search out what number of kilos of lean physique mass you might have.
200 x 0.8 = 160 kilos of lean physique mass
Because you’re 20% physique fats, you’ll wish to eat 1.5 grams of protein per pound of lean physique mass.
Subsequent, you’d multiply your lean physique mass in kilos by 1.5.
160 x 1.5 = 240
You’d wish to eat 240 grams of protein per day whereas on a protein sparing modified quick.
Now let’s say you’re a 160-pound lady with 40% physique fats.
First, discover what share of your physique is lean mass by subtracting your physique fats share from 100.
100 – 40 = 60% lean mass.
Convert this to a decimal:
60% = 0.6
Multiply your physique weight by the end result to search out what number of kilos of lean physique mass you might have.
160 x 0.6 = 96 kilos of lean physique mass
Because you’re 40% physique fats, you’ll wish to eat 1 gram of protein per pound of lean physique mass.
Subsequent, you’d multiply your lean physique mass by 1.
96 x 1 = 96
You’d wish to eat 96 grams of protein per day whereas on a protein sparing modified quick.
2. Eat some low-calorie greens.
You don’t technically have to eat any greens whereas on a protein sparing modified quick, nevertheless it makes the method a lot simpler.
You’ll be capable of chew on one thing aside from protein, your digestion will likely be higher, and also you’ll really feel extra full after meals.
Plus, it helps scale back the probability of any nutrient deficiencies (though you shouldn’t keep on a PSMF lengthy sufficient for this to be a difficulty anyway).
Some good choices for low-calorie, high-fiber veggies are:
- Inexperienced beans
- Zucchini
- Broccoli
- Cauliflower
- Squash
- Leafy greens
- Kale, collard greens, and so on.
- Asparagus
- Cabbage
- Pickles
- Cucumbers
3. Take the precise dietary supplements.
You don’t have to take any dietary supplements whereas following a PSMF, however doing so will make the method rather more pleasing.
To start with, it’s value taking a serving of fish oil day by day.
Though you may go a number of days to some weeks with out consuming important fatty acids, like these present in fish oil, they’re value taking.
There are tons of if not hundreds of capabilities within the physique that rely upon these important fatty acids, and it’s higher to be secure quite than sorry whereas following a restrictive weight loss program like this.
You’ll be able to take any high-quality fish oil, however I like to recommend Triton. An efficient dose of fish oil is 500-to-3,000 mg, or 4 capsules of Triton.
Subsequent, I like to recommend you’re taking a superb multivitamin.
You gained’t be capable of meet the RDI for many vitamins whereas following this weight loss program, so taking a properly formulated multivitamin is an efficient solution to reduce the danger of nutrient deficiencies.
You’ll be able to take any high-quality multivitamin, however I like to recommend Triumph. It’s particularly formulated to include the entire vitamins that athletes are usually missing, together with a number of vitamins that most individuals don’t get sufficient of (corresponding to vitamin D3 and K2).
I additionally advocate you closely salt your meals with both desk salt or a mix of desk salt and potassium salt (like No Salt). There isn’t a lot scientific proof behind these dietary supplements, nevertheless it’s properly established that low-carb diets (like a PSMF) can deplete electrolytes.
Taking these minerals additionally appears to assist scale back the lethargy attributable to excessive calorie restriction. (Oh, and it’s greatest to take potassium together with your meals, not in pill kind, because it’s straightforward to take an excessive amount of by accident.)
It’s additionally value taking 600-to-1,200 mg of calcium and 500 mg of magnesium day by day, for a similar causes—these minerals are sometimes arduous to return by on very low-carb/calorie diets. Any model of calcium will work, however for magnesium, I like Legion’s Sucrosomial Magnesium complement.
Lastly, I usually advocate you keep away from protein powders, bars, and different calorie-containing dietary supplements.
Dietary supplements sometimes aren’t as satisfying as complete meals, and also you don’t have any spare energy to “spend” on them when following a PSMF.
In case you insist on getting a few of your day by day protein wants from protein powders, I like to recommend you’re taking a high-quality casein isolate protein. Casein takes longer to digest than whey, and usually does a greater job at serving to you keep full.
You’ll be able to take any high-quality casein protein isolate, however I like to recommend Casein+.
So, in abstract, listed below are the dietary supplements I like to recommend whereas on a PSMF weight loss program:
- No less than 500-to-3,000 mg of top of the range fish oil (like Legion Triton) per day
- A full serving of a top quality multivitamin (like 8 capsules of Legion Triumph) per day
- Beneficiant quantities of desk salt and potassium (in your meals) day by day
- 600-to-1,200 mg of calcium per day
- 500 mg of magnesium (like Legion’s Sucrosomial Magnesium) per day
4. Elevate weights not more than 2-to-3 occasions per week.
Lifting weights is among the single greatest methods to keep up your muscle when limiting your energy for fats loss, and it turns into an increasing number of essential the extra you prohibit your energy.
Fortunately, although, it takes far much less weightlifting to keep up your muscle than it does to construct it within the first place.
Because of this you may scale back your coaching quantity by wherever from ½ to ⅓ of your regular coaching quantity for a number of weeks with out dropping energy or muscle.
So, when following a PSMF, elevate weights 2-to-3 occasions per week, sticking to comparatively brief exercises involving compound workouts just like the squat, bench and army press, and deadlift.

5. Do some cardio.
You don’t have to do cardio whereas following a PSMF, however it would assist you lose fats quicker.
One other facet advantage of cardio is it offers you one thing to do whenever you may usually be consuming, getting ready meals, or cleansing dishes.
Even a 20-to-30 minute day by day stroll will assist you burn some further energy, with extra being higher.
You are able to do any type of low-impact, low-intensity cardio you need, nevertheless it have to be low depth. You shouldn’t be doing any HIIT or something that makes it tough to breathe throughout your exercise.
