Jumping straight into the Beef & Butter Fast cold turkey (or should I say cold beef 😆) from a diet full of sugar and carbs, is like trying to run a marathon after six months on the couch—it’s gonna hurt, and your chances of failure are high. To avoid questioning all your life choices by lunchtime on Day 1, here are some strategies to make the transition smoother and help you prepare for the beef and butter fast.

This is a follow up post to the announcement about our Beef and Butter Fast experiment (aka. IBIH Beef Week as some are calling it. 😂) that’s designed to help you prepare for the beef and butter fast next week. Our official start date is Monday, February 17th – which is in 3 days.
Since this is the first time doing this for many of us, I put together some tips and strategies that you can implement now to prepare for the beef and butter fast, and minimize the painful detox effects and potential anxiety around starting on Monday.
You can use some, none, or all of these strategies to prepare for your beef & butter fast – they are optional and here to help you on your 7 day all beef adventure. 🙌🏻😆
1. Reduce Sugar & Processed Carbs in Advance 🍭➡️
- If you go from a high sugar diet straight into beef and butter, your body is going to throw a tantrum. Headaches, fatigue, and a sudden urge to throttle anyone eating a bagel near you? That’s sugar withdrawal.
- Start reducing sugar and refined carbs a few days early, so your body can ease into using fat for fuel without totally revolting.
- Soda, iced tea, fruit juice? Those are low hanging fruit – ditch them now and get a head start on next week!
- Swap out sugary snacks for high protein ones like cottage cheese, yogurt, and hard boiled eggs – your body will thank you.
2. Say Goodbye to Gluten & Processed Junk Before the Fast Begins 🍞🚫
- If you’re still eating bread, pasta, or ultra-processed keto snacks, ditch those now to get a head start on your detox.
- Gluten detox is one of the worst ones for me, and always results in a bad headache and an even worse mood for the first couple of days. I get it if you want to go out with a bang on Sunday night with a big meal of your favorites before just beef and butter, but even cutting way back on the gluten and grains in the meantime will help signal your body that this party is almost over.
- If you start this process before the fast, you can greatly reduce how terrible you will feel by day 2 and 3 – which means enjoying the feel good effects of this fast even sooner, and with less trauma – both physical and emotional!
3. Ease Into More Fat & Protein
- If your body isn’t used to running on just fat and protein, it might take a few days to adjust (translation: don’t be shocked if you feel “off” at first).
- Start upping your butter, fatty meats, and eggs now (within reason) to prepare for the beef and butter fast, so your digestion isn’t in for a rude awakening when you go all-in on Monday.
4. Stock up on Electrolytes – Seriously.
- One of the fastest ways to feel like hot garbage during this fast is to ignore your electrolytes. Without carbs, your body dumps water and salt like Niagara Falls, so you need to replenish it constantly!
- Solution? Make sure you’re stocked up on sea salt (table salt contains no nutrients) or Redmond’s real salt, and whatever you need to prepare for supplementing with potassium (I like Nu Salt) and magnesium – otherwise you might wake up in the middle of the night with a leg cramp that makes you hear colors.
- If you want simple, you can try these electrolyte drops that contain all of the essentials with no sugar (not affiliated, just a recommendation if you like an all in one solution.)
- Also Bone broth is your new best friend—it helps with gut health, electrolytes, and makes everything feel warm and cozy, so start a batch this weekend so you’ll have enough to get you through the entire week of the beef and butter fast.
5. Giving Up Coffee or Tea? Start Weaning Off NOW ☕➡️😵
- Caffeine withdrawal + carb withdrawal = a one-way ticket to Miseryville.
- If you plan to quit coffee or tea during the fast (Full disclosure, you’ll have to pry my coffee out of my cold dead hands), cut back gradually NOW in preparation for the fast, so you’re not experiencing double withdrawal next week.
- If you’re keeping caffeine (like a sane person 😂), just be aware that drinking it black without sugar or cream might take some getting used to. I’ll be drinking espresso, which I already enjoy, and it will still be weird to have it in the morning (in addition to my 3pm pick me up) because I’m used to my coffee with cream.
6. Meal Prep = Your Lifeline.
- The last thing you want on Day 1 is to be hangry, unprepared, and staring at raw beef like it’s a puzzle.
- Pre-cook some ground beef, steak, or shredded beef, portion out some butter, and have everything ready to go so you don’t have to make any decisions when your brain is already mad at you.
- No need to prep the entire week, but get a head start on those first few days to make the beef and butter fast easier on yourself.
7. Embrace Simplicity (and Say Goodbye to Variety 😭)
- Look, this is NOT a Michelin-star meal plan. There will be repetitive meals. There will be moments when beef feels like a chore, and maybe even a punishment. That’s normal.
- Please remember that the goal here isn’t food excitement—the beef and butter fast is about metabolic reset, fat-burning, and cravings control.
- But that doesn’t mean you have to eat the same thing every day – get a variety of beef cuts so your meals don’t feel like you’re trapped in a Groundhog Day of the same textures. 😵💫
- Refer back to the original Beef & Butter Fast Post for meal ideas to keep it interesting!
- Instead of focusing on what’s missing, remind yourself this is temporary, and in just a few days, your cravings will be GONE, your energy will skyrocket, and your body will be a fat-burning machine.
- Enjoy that you aren’t cooking complex meals all week – just think of all that time you’re saving! ⏰
8. Prepare for Odd Emotions to hit you Randomly Throughout the Week
- Sometimes it’s the changes in routine or cherished habits (giving up your favorite morning coffee preparation, a glass of wine in the evening, popcorn with your movie night, dinner out with friends) that are what get you down during a fast like this. 😞
- So prepare yourself in advance for changes you plan to make, so you aren’t blindsided with the potential emotions (sadness, anger, frustration) that might come with making these adjustments during the beef and butter fast.
- Remind yourself that it’s only a week, and the results will be worth it! 🥳
9. Line up Distractions for Yourself in Advance (That Aren’t Food)
- Use these next few days to think about, and if necessary shop for, some projects or activities that can keep you busy (especially at night during the dreaded snacking/wine drinking window of fasting doom) during the fast.
- I’m planning to do some seed starting for my spring garden, 🌿 finish a paint by numbers project that has been sitting in the corner for the last 14 months, 🎨 give myself a pedicure 💅🏻 (or splurge on one out), and finally get through the mountain of clothes 👗 that I need to go through and figure out what we are keeping, and what is getting donated.
- Those are just a few ideas that you can also use, or visit your local hobby store (or amazon) and take up a new crafting hobby, or DIY project.
- Just remember that you will probably be fatigued and cranky the first few days – so don’t plan anything too hard core (like renovating that guest bath from the studs out) that will just make the beef and butter week overwhelming. 😩
- Be modest about what you can handle, and pick something that you will actually look forward to doing and that will keep your mind off of snacking.
Hopefully these strategies will help you to prepare for the beef and butter fast in advance, resulting in the easiest possible detox phase, so you can sail through the week like a champ!

How many times do you eat the beef and butter daily? I didn’t see that and is there a window for meals. Like don’t eat after the sun goes down?
Mellissa Sevigny says
You can eat when and however much you want – your body will regulate and you won’t feel hungry after the first couple of days.

Hi Melissa !
We’ve been using your recipes for quite a while now. Started back up ( we live in Mexico now and the food is so fresh and good ) and I’m down 16 pounds but hubby is stuck and wants to try this. I buy taco seasoning at the little tienda near us and they do not put sugar or lime in it – would that be ok to use ? I’m sticking with the regular low carb as it’s working well for me and I’m not a hamburger fan but love a good steak.
Hope you and yours are happy and well !
Rebecca

Sorry I didn’t see this message until today, but taco seasoning without sugar would probably work just fine on this fast! Let us know how it goes!
Rebecca Cramer says
Hi Melissa !
Hubby did great on the b&b diet ! Lost 8 pounds! Sorry it took me so long to get back to you !
Mellissa Sevigny says
That’s awesome, thanks for the update!
Bill McBerger says
You are so funny! And completely right
Mellissa Sevigny says
Music to my ears Bill, thanks! 😂
Elin says
You suggest having bone broth. How would I make that so it fits this fast? Storemade bone broths have ingredients that wouldn’t be permissable. Thank you for all your insights and humor!!
Mellissa Sevigny says
Beef bones, salt and water if you want it to be truly compliant!
Brian Willsey says
Would lamb work the same as beef?
Mellissa Sevigny says
Theoretically, any ruminant animal is fine. But I’d do your own research to be sure!
Julia Ann says
With these tips I think I’m ready to take on the challenge. See you on Facebook.
Mellissa Sevigny says
Woohoo!
DavetteB says
I’d strongly suggest not trying this unless you’ve already been Keto for a while. The Beef and Butter website made it even more simple by just scrambling up ground beef and seasonings, plus butter; I found it easy to scramble up a panful and put my bowls in the fridge. HTH

We have bad weather here in Michigan so have not been able to shop. I might be able to get started with what I have on hand. Would black decaf coffee with MCT oil and butter in the morning be appropriate? Thanks for all your great recipes and menu plans. I have purchased both your books and followed Squeaky Clean for 5 months back in 2021. I lost 38 lbs and felt great.
Mellissa Sevigny says
I’d skip the MCT oil and just go with the butter!
gjeanieg says
Mellissa, thank you for this! I will be participating from the sidelines. =)
Mellissa Sevigny says
We will need some cheerleaders, thank you! 😘
gjeanieg says
So, I decided to jump right in. Today was DELICIOUS… Hope that lasts for a while, and hope it encourages someone out there to join. Thanks again, Mellissa!
Mellissa Sevigny says
So happy you are joining us!

Good tips. I have followed you and your Keto recipes for years, then I started researching the Proper Human Diet. I have been Beef, Butter, Bacon & Eggs for many months now. I have to force myself to eat after I have a ribeye and six eggs for my 3:00 p.m. meal. Just know you will not be hungry if you have the 1 to 1 fat/protein to start. Do not worry about calories when you eat this way. Your body absorbs protein and will love the fat to burn for energy. Worry about calories when you eat carbs–not Carnivore or BBB & E. Make sure you use good Celtic Sea Salt or Baja Gold and lots of it. It’s good for you. Going BBB&E was easier because I had more options. Eggs are nature’s multivitamin so think about transitioning once you detox. It probably takes more like 30-days to fully shed the oxalates and reset the insulin/glucose/microbiome. I had labs done after 30-days of BBB&E and my glucose dropped 10 points. It’s real people. Stick with grass fed, grass finished beef and butter if you can afford it. Your poops will be odd at first. You may not go for two or three days because you ditched the garbage and plants…and you mostly absorb all the protein into muscle. Best of luck!

Thanks so much for these insights Catherine!
