The 21 Day Fix’s 3 Day Quick Fix is designed to get you bikini and/or photo shoot ready in just three days, but what exactly is it?, does it really work?, is it for everyone?, and are there any tips to maximize results?
That’s what I’m going to share with you in this review post.

What is the 21 Day Fix’s 3 Day Quick Fix?
The 3 Day Quick Fix is the same eating plan Autumn uses to get ready for her bikini competitions and photo shoots. It’s a high protein, low-carb, and low-fat diet designed to reveal your sleek sexy 21 Day Fix program results.
I figured since I was doing the 21 Day Fix to the best of my ability, then fitting the 3 Day Quick Fix in the final three day of the program was mandatory for a full program experience.
3 Day Quick Fix Allowed Foods
I’m not going to make this sound any better than it is – the allowed foods list is small, but you have to remind yourself it is only for three days to get yourself ready for your after photos. Limiting yourself to these foods is going to create an amazing difference to your body, so it makes how mundane the foods list is worth it.
What you CAN eat:
Steamed Vegetables
Lean White Proteins
Steel-Cut Oatmeal | Steamed Yams
Limes, Lemons, Spices
What you CANNOT eat:
Shakeology
Fruit
Salt
No Shakeology?…what do you mean, no Shakeology?!!! All kidding aside, this is the one thing I missed most while following the 3 Day Quick Fix – and fruit!
You also are not allowed carbs after noon, which was doable, as was eating no fruit for three days. Of course, the no carbs after noontime does take its toll on feeling less energy than usual, so make sure to get your workouts in earlier.
You get six meals, spaced 2.5 hours apart. The first two meals include carbs, the last four meals are protein and veggies with coconut oil mixed in with three of them.
My 3 Day Quick Fix Shopping List
You might look at the 3 Day Quick Fix meal plan and think, is that really all? At least, that’s what I was thinking when I first looked at it. That’s one great thing about the Quick Fix diet it’s simple – there’s not a whole lot of shopping that needs to be done or choices to be made.
If you start adding in foods or subtracting out foods, you are not following the 3 Day Quick Fix diet. You either choose to follow the diet or not – it’s entirely up to you.
Here’s a list of what you’ll need:
- steel-cut oatmeal
- 2 yams
- 24 egg whites
- 1.5 lbs chicken breast
- 1.5 lbs wild caught cod loins or other white fish
- .75 lbs extra-lean ground turkey
- extra-virgin coconut oil
- broccoli, asparagus, green beans, zucchini, cucumbers, bell peppers
- 3 gallons of water
The above list is for women. Men would need a bit more food, which is explained in the guide.
Optional foods:
- lemons and limes
- vinegars
- no-salt spices
- nutmeg
- cinnamon
- stevia
- coffee and/or teas
It would also be easy to grocery shop, and then meal prep for the 3 days if you chose to do so, although preparing eggs ahead of time seems a little gross…at least to me.

What is the Deal With All the Coconut Oil?!
If you’re familiar with Autumn’s programs, then you know she likes to include coconut oil…a lot. And the same holds true for the 3-Day Fix diet, which has you eating lots of protein and veggies with a little bit of fat thrown in there every day: prepare yourself for 1 tsp of coconut oil with 4 out of 6 meals to be exact.
Why coconut oil? Because coconut oil is a little different than other oils. The body does not break down coconut oil into fatty acids; instead, it breaks down into medium-chain fatty acids that go straight to the liver. It then acts more like a carb in the human body by providing immediate energy, but you also get the healthy fat your body needs to maintain optimal functioning.
What type of coconut oil? Through my research. coconuts do not get a heavy amount of pesticides. They hang high in trees and pesticides that are used in soil are said not to reach the flesh of the coconut. So, USDA certified organic is not something of to much concern. But, I would advise choosing either a virgin or extra-virgin coconut oil. Virgin or extra virgin oils are first processed oil which means you get the most nutritional value from these over more refined processed versions.
Does the 3 Day Quick Fix work?
I wish I’d taken a photo before and after the 3 Day Quick Fix to visually show you the result difference it made in three days, but in short, yes, it does work, and it does make a noticeable difference. If you’re trying to look your best in the three week program, then you will definitely do not want to skip out on this. It is mostly water weight, but it does make an immediate difference.
I did feel like it zapped me of a lot of my energy, but I did choose to do it my last three days of the program. Doing double workouts each day along the Quick Fix might have been a little too much for me personally.
I also tend to get a low blood sugar feeling if I go too long without eating, and eating carbs all early in the day definitely affected my workouts as I usually workout in the evening. In hindsight, I should have tried to sneak the workouts into my morning routine.
When to Follow the 3 Day Quick Fix
The small booklet tells you to follow the 3 Day Quick Fix the last three days of the program to get you bikini (and photo shoot!) ready. It also gives you a variety of other of occasions when you may choose to follow the plan. It definitely comes down to when you want to look your best and get leaned out, or even to get your eating habits back on track.
At the end of the program on Day 19 is when I chose to follow the diet. I was following the plan exactly and wanted my after photos to look the best possible. I also think you might benefit from following the Quick Fix on your first three days. This way when you start following the regular portion control 21 Day Fix diet plan, it feels more flexible and easier to manager.
Please note that the 3 Day Quick Fix is only to be followed for the three days and is not intended to replace a healthy, well-rounded diet. It is not a sustainable diet, and you should not do it more than once during the three-week program.
If you are following multiple rounds of the 21 Day Fix and not necessarily working towards a day in a bikini competition or photo shoot, I would not say the 3 Day Quick Fix is necessary to having long-term success with the program.

Hi, I don’t eat Quinoa, Oatmeal or Brown Rice. Is it OK to eat Mashed Potatoes and Grits doing the 21 Day Fix?
Hi Sherry, those should be fine depending upon how they are made. This post just covers the 3 Day Quick Fix part of the program for those who choose to do it.
Hi, I start my 21 days fix 7 days ago. And looking at guide for this 3 days quick fix. Is the Meal 1 to Meal 6 is our Menu for each day? meaning I have to eat those 6 meals a day? Thank you.
Hi Maye, When following the 3 day quick fix plan it is. Most people do the 3 day period at the end of a round of the 21 Day Fix or when they need to cut water and bloat to get an extra lean look for an event. It’s not something you should be doing all the time.
Hi
Inam adding all my veggies and making one big salat is that ok?
I work nights and it is hard for me to eat 4 times veggies spaced out
Hi Konul, It is best if you could eat every 2-3 hours, but sometimes life just does not make that possible. Just do your best!
thank you for your answer. How do I make oatmeal for the 3 day quick fix plan?
Hi Najwan, Stove top or microwave should be fine per the cooking instructions. Just remember that it is plain old fashioned rolled oats that you want to use.
Hi, I am about to start my 21 day fix. I will be starting tomorrow. I am just confused about the three day quick fix, what workouts am I supposed to do for it? or do I just follow my regular workout routine? And for the food guide for the three day quick fix, what does (e.v. coconut oil stand for)?, like how many spoons? And for the 21 day fix program, am I okay to make my own food and measure it? for example, can I still make my veggie stir fry with mushrooms , olive oil, peppers, and broccoli?
HI Najwan, I would recommend doing the quick fix at the end of your 21 Day Fix round. You can follow the normal workouts or adjust to something lower intensity if you need to. The e.v. stands for extra virgin which is measured with the tsp. And, yes you you make your own food and measure it yourself, I like to keep a check sheet hand so that I can mark down what containers go into a recipe to make it easier for future use.
Good morning,
I am so glad that I ran into your web page, because I am starting the 21 Day Fix and I planned on starting off with the 3 Day Quick Fix since I ate so bad over Easter weekend!
Thank you for posting all this good info :)
Hi Tammy, I know what you mean about Easter, but those are the times when living a healthy lifestyle allows for some good times too. Goof luck on the Fix! Bethany
Can I substitute canned tuna for steamed fish?
Hi Chels, That is a good question, technically canned tuna has been steamed during the canning process. I do however believe the guide is referring to fillets of white fish that you steam yourself.
What time is too late if I didn’t get my last meal in?
Hi Danielle, I believe a couple of hours before bed would give your food time to begin the digestion process.
What is the serving size for the vegetables?
Hi Erin! The green container is about one cup. Hope that helps! Bethany
Is there something else you could replace the oatmeal with? I’VE BEEN TRYING REAL HARD BUT BY THE FORTH BITE I’M IN TO GAG MODE. Lol
Hi Kim, I find steel-cut outmeal to better than the rolled too. Guess you could add in more yams.
Can you eat salmon?
Hi Aimee, On the 3 day quick the guide wants you eating white fish.
What can I eat in place of fish? I have tried to eat fish but I gag.
Hi Linda, The 3 Day Fix does not list any substitutes. I guess you could exchange for other lean meat proteins, but it is probably not optimal to do so.
Do you have to eat all of the food on the 3 day quick fix for the 21 day fix
Hi Damarrius, I would. It is very low calorie as is.
I do all grilled chicken and during the meal that is fish I take a fish oil pill. I also gag from the coconut oil so I bought it in gel capsul form
Hi Ashley, The coconut capsules are a good idea, thanks for sharing. Bethany
Ashley…can I ask which coconut oil capsules you use? what dosage and how many pieces do u take a day?
How many egg whites for one serving I’m confused
Hi Tonia, Yes 6 egg whites is a serving.
1 egg white ,two egg whites, how many egg whites makes up a serving
6
Actually, the book states that 8 egg whites is 1 serving.
You’re right! Thanks for the comment!
3 eggs whites is the most you can fit in one container
Hi, Egg whites from large eggs contain about 17 calories and 3.5 grams of protein each. For a few foods like egg whites you don’t necessarily use the containers but refer to the eating guide for the most accurate serving sizes. Bethany
Hi Bethany,
JHow do you cook the lean ground turkey? Can you use olive oil?
Thanks
Hi Maria, I used mt Misto olive oil spray bottle to season the pan.
Bethany, for the protein are you doing 4oz raw when measuring? or is there another measurement for the 3 days?
Hi Pam, Yes, 1 red container.
Quick question, can you eat just two types of meats/red (turkey and chicken – and egg whites) or you must eat cod and tilapia?
Hi Cal, The guide does not say that you can make replacements.
Is there a replacement for oatmeal haters? Could I have steamed yams instead? Thanks!
Hi Racheal. For best results I would try to stick to the program as is, the guide does not list any substitutions which kind of stinks.
It calls for yams are they the same as sweet potatoes?
Don’t know if this is a cultural thing but yams and sweet potatoes are two different things at my store. Maybe you can clarify?
Hi Leslie, Yams and sweet potatoes are two different tuberous root vegetables, and they should be two different choices at your grocery store, although some grocery stores don’t even categorize them correctly.
For measuring in the containers, is this raw or cooked? I just started the program and doing the 6 egg whites. I could only fit 4 whites in the container?
Hi Darlene, I would double check with guide, I believe you don’t have to use the containers when it lists the amount of a food.
I can’t eat 6 times a day or I’m eating my last meal at 830 pm. Can I double up my 630 pm meal?
Hi Amy, While it would be best to squeeze the last meal in if you can’t doubling up would be better than skipping it.
Do the vegetables on 3 day quick fix have to be steamed or is it ok to eat some raw?
Hi Kelly, I’m pretty sure it is steamed vegetables only, raw vegetables are probably harder on the digestive system. Bethany
