How does fat loss and body composition work on the Carnivore Diet?

In this article you’ll learn how to approach losing fat and improving your body composition with the Carnivore Diet.

Physique, Fitness, Fat Loss and Performance on the Carnivore Diet

Many people’s fitness goals when starting the Carnivore Diet fall into a few categories:

  1. How to lose fat
  2. How to build muscle

And how to build the physique you want while feeling good, not starving, and making it sustainable long term. The Carnivore Diet is an exceptional way to finally discover fitness AND health. This is the ultimate goal, to look great AND feel great. (The keys to this kingdom are in the Meat Health Masterclass which you can watch at the end of this article)

Warning: If your #1 priority is short term fat loss, the Carnivore Diet may not be the best choice.

But if you want to have a body composition you love, long term, along with health, you are in the right place.

The first place to start when using a meat-based, Carnivore Diet, to create your ideal body composition is getting adapted. Use the 30-Day Guide to get there.

For some people this takes 3-6 months, for other it can take years depending on the damage done.

Getting Adapted

Nearly 100% of people see a drop in performance while getting adapted to the Carnivore Diet.

Don’t go carnivore if you have a strength training meat (pun intended) this month.

Strength tends to catch up and improve quite rapidly. More glycolytic type training, like hypertrophy training that bodybuilders tend to focus on, takes a bit more time to get to the level you were at. It also takes more time to regain some of the muscle fullness (which might always be a bit less full than if you incorporated carbohydrates).

It takes many athletes 3-6 months to recover their prior level of performance, however, after this recovery period I’ve seen people who had not been able to make strength or size or performance improvements start to shatter their previous bests.

During adaptation you may experience increased soreness. Explosiveness takes some time (the highly glycolytic stuff) to get back. Strength generally goes up quite rapidly, but athletes can take up to 3 months to get fully back up to speed before dominating to new heights.

If you want to find a diet where you can feel and perform amazing while having health (ENERGY, FOCUS and VITALITY), the Carnivore Diet is one where you can have your steak and eat it too.

Before diving into some of the common questions PLEASE read this on “TINKERING” with the Carnivore Diet. It’s absolutely not something you want to do when starting. But for thriving carnivores that want to tinker, there are strategies to stay on protocol while optimizing for various variables like strength or size or fat loss or endurance or performance.

Post Workout Carbs and Cortisol

Many people worry about the elevated cortisol. Post workout carbs are often used as a strategy to lower cortisol post-workout. But these transient spikes in cortisol isn’t something to worry about. Your steak is all you need. As a thriving carnivore, your chronic systemic inflammation is low day in and day out. Acute inflammation from a workout is good and natural. Your delta between your chronic systemic inflammation and your localized acute inflammation as a carnivore is large which is good, your body knows how to allocate resources most effectively to repair and grow those muscles you just put to work. Just feed it the resources it needs. Steak. Your non-carnivore friends have a smaller delta between their chronic systemic inflammation and their localized acute inflammation. They likely have chronically higher cortisol levels and allocation of resources for repair are not as efficiently resourced because some need to go help the whole body inflammation (chronic) and some to the (acute). It’s important to see the forest through the trees.

Plus, there’s no difference in glycogen replenishment eating immediately vs 4 hr post-workout.


For most people, and most people’s goals, there’s no need to supplement. For example, creatine is a proven, effective, safe supplement. But red meat is the best source of creatine there is. Most people’s creatine stores will be “topped off” on a Carnivore Diet. Adding a couple grams a day probably has little to no negative impact, but also likely no benefit.

Protein Supplements: You’ll almost always be better off eating whole, real, meat. 

Counting Calories and Macronutrients

Being “aware” is better than being “analytical” here.

For example, if you are focused on building strength, eating a bit more is going to help. And if you’ve gone through the adaptation you likely have a good idea on average how much you eat, of what, to thrive. If you are wanting to gain strength and size you need to give the body the raw material (steak) it needs to add on this growth. All this requires is eating enough, and if strength or size has stalled you may need to eat just a bit more.

If you are wanting to get really cut. Being aware that you need to fulfill the equation: burn more energy than consumed. Generally you just need to substitute in slightly less fatty cuts, and burn some more energy.

Stalled Weight Loss

Weight loss is not linear. Most people who are focusing on fat loss and have above 10% body fat for males and 15% for females, just need to continue to eat meat and heal. They need to throw out the scale and just trust the process. Healing can take 3-6 months or a couple years depending on the extent of the damage. Focus on good nutrition, health first. Then focus on getting stronger and fitter. Lift weights, increase your HIIT capacity. Stalled fat loss should trigger you to focus on increasing strength and cardio capacity, not decreasing meat.

If fat loss has stalled and you are wanting to get super cut, see the Meat Health Masterclass at the end. Naturally, the body doesn’t like 4% body fat, so you have to force it there.

Regained Weight and Plateaus

Remember – weight loss is not linear. And weight or fat gain when starting a carnivore diet is not uncommon. As hard as this sounds, you have to trust the healing process. You need to throw out the scale. You need to keep eating meat when hungry until full. Your focus during this healing time should be on getting healthy first.

How to Transform Your Body and Health with a Meat-based Diet


  1. I’ve been on Carnivore for about 6 mos. I am male, 5’8 and 180lbs. During the first 3 mos i did nothing but beef, salt, coffee and water, 2 meals a day, 16X8 or 18X6 and got down to about 167 lbs. My wife who was also doing Carnivore was really struggling with fat digestion and electrolyte issues. Due to some chronic health issues she can’t take electrolytes or causes her bladder discomfort. Long story short, we started incorporate ALOT of Butternut Squash (like half a butternut squash each 4 – 5 days a week), Butter & Cheese during November & December and I started gaining weight. I had stopped weighing myself but i could tell by looking in the mirror. Come January 1st and I went back to just beef, a little cream in my coffee and a little cheese. I felt like i dropped a lot of water weight but at the end of January, I jumped on the scale and i was back to 180! So, I cut out all cream, cut out the cheese and went back to just beef, salt, coffee, & water and 18X6 Intermittent Fasting. 3 weeks later and I’ve gained another 3 lbs.

    Now, I see stories all the time of people not losing weight until they’ve adapted, but I don’t see anyone saying they lost and then started gaining. It’s pretty demoralizing. Maybe I need to give my body more time to recover from a couple month of butternut squash an d maybe 3 mos of cheese, but I certainly would have expected a quicker turn around of weight loss given my original success going beef, salt, water & coffee.

    I’ve probably been eating 2 – 3lbs of ribeye/NY strip a day. I get so frustrated reading people say you can’t over eat on protein while others recommend eating 1Gram of protein per target body weight. So if I want to get to 160lbs, that suggests I need to limit my steak/beef intake to about 20 ounces per day and up the fat.

    Any thougths, recommendations?

    1. Hi Brett, lots of great questions here.

      Yes I think you are looking at things on too short a time scale (weight loss isn’t linear) but also throwing in lots of variable with lots of butternut squash 🙂

      Meat Health Academy is launching in ~1 month, and from the sound of it, I think you and your wife might be a real good fit.

      1. I’ve started logging everything in Cronometer. I know the appeal of Carnivore is it’s simplicity, but I felt I needed to get a better handle on some metrics and make I wasn’t having selective memory of what I was eating.

        Between that and upping my daily activity, I feel like I have turned the tide but decided to avoid the scale for a while.

        Is there a link to learn more about Meat Health Academy?

  2. Hi Doc

    Thanks for all the great info! I’m curious for your thoughts on how to best ease into carnivore (I’ve read your 30 day guide and will start level 3-2) but I’m planning to come out of a 600 a day calorie low fat low carb kick start month and am conscious of weight gain. Should I slowly increase the calories or not worry about calories and slowly increase the fat ? Appreciate any thoughts you may have. I am aware I am likely to gain weight at first just want to be able to control it as best I can. Looking forward to this lifestyle and healing my body (and unhealthy belief I need to restrict!)

    1. Hi Lee, it’s actually a loaded question, as I’m betting (but not sure because don’t know your history / goals) but I’m guessing I wouldn’t have recommended a 600 calorie low fat low carb “kick start month”

      As to what you should do, it entirely depends on your goals. If you go right to eating as much as you want, even if it’s just meat, you are likely going to put on some fat. If that is unacceptable, then I would likely do a reverse diet, but there are all kinds of pros and cons to this.

      I am going into depth on these topics very soon, if you can hold on about 2 months!
