What’s the difference between Perfect Keto vs Bulletproof?
At first glance, both diets may seem as if they’re the same approach to eating with their emphasis on healthy fats and eliminating sugar.
But as you’ll see in today’s guide, that’s not the whole truth.
While overlaps between Perfect Keto and Bulletproof do exist, there’s also several key differences you need to be aware of too.
Because of that, today’s guide dives into the following points:
For a better idea of both players involved in the Perfect Keto vs Bulletproof showdown, let’s start with everything you need to know about team Bulletproof first.
Dave Asprey, a tech entrepreneur and biohacker, spent over $1 million trying to figure out how to make his body run like the ultimate smart machine.
In doing so, he lost 100 pounds and shared his secret formula in his bestseller The Bulletproof Diet.
According to Asprey, his three-digit scale victory was achieved without having to count calories or work out like a savage.
So how exactly did all that weight melt away?
The core of Asprey’s Bulletproof Diet is a roadmap of foods divided into three color-coded categories that work almost like a traffic signal:
- Green zone foods can be enjoyed without worry like an all-you-can-eat buffet.
- Yellow zone foods should be consumed with caution and mindfulness as they can trigger digestive upsets and other unwanted side effects.
- Red zone foods should always be avoided.
You’ll also follow specific serving sizes to eat and get an idea of the best times to eat in Asprey’s book. So while you’re not counting calories, you’re still using your portion control skills.
Let’s talk about the specific types of foods allowed on the Bulletproof Diet.
Basic Principles of the Bulletproof Diet
On top of separating foods into different categories, people following the Bulletproof plan should also:
- Eliminate sugar and replace it with healthy fats
- Opt for wild-caught fish and grass-fed meats
- Stop eating gluten, grains and legumes
- Avoid foods with artificial and chemical additives, preservatives, flavors and colorings
- Go for raw, full-fat dairy from grass-fed animals only
- Choose organic veggies and fruits
- Cook food at temperatures lower than 320℉
- Cap your fruit consumption at 1-2 low-fructose fruits per day
After reading those points, you’re probably thinking the Bulletproof Diet sounds a little familiar — and that’s because it is.
Similarities With A Keto Diet
In addition to the off-limits foods and basic core principles, people following Bulletproof limit their carbs while upping their healthy fat intake — much like in the keto diet.
Bulletproof claims it’s a ketogenic diet, however, is not the standard ketogenic diet (SKD).
Rather, it’s what’s known as a cyclical ketogenic diet (or CKD for short).
On this keto plan, dieters follow a SKD for 5-6 day bursts and then they have one or two carb refeeding day(s).
While the daily net carbs for these days can be as high as 450-600g for some, they’re not for carb-loading pasta or pizza.
They’re for carby splurges more like squash, white rice and sweet potatoes.
When used this way, ketosis becomes a tool to use some days — not the only state people are in — according to the Bulletproof mantra.
Asprey and his team say following this way of eating can lead to benefits such as:
- Becoming highly resilient
- Massive increases in energy
- Lower inflammation
- Improved cognitive function
- Fat loss and muscle maintenance
- Balanced hormones and blood glucose levels
The Bulletproof Diet has also evolved into a whole line of coffee and supplemental products to support people following this style of eating.
Now that you have an overview of what the Bulletproof diet is, it’s time to move on to Perfect Keto and see where it differs from Bulletproof.
Here’s the Perfect Keto (PK) story in a nutshell:
- PK was founded by Dr. Anthony Gustin, a sports chiropractor, functional medicine provider and entrepreneur.
- Dr. Gustin questioned the BS diet advice taught to him in his doctoral level nutrition classes so he decided to challenge the traditional dietary norms by researching the positive effects of a ketogenic diet.
- Keto helped him lift his mental fog, eliminate body aches and gave him a noticeable difference in his overall body composition.
- Perfect Keto is Dr. Gustin’s way of helping others find the same success. Perfect Keto has expanded from education about ketosis to keto-friendly supplements and food products that support a healthy, easy, and tasty ketogenic diet.
Dr. Gustin believes the secret to your healthiest life ever is optimizing the four pillars of health:
And unlike Bulletproof, Perfect Keto can be used for more than a cyclical ketogenic diet, as we’ll see next.
The Ketogenic Diet
While Bulletproof is mainly focused on a cyclical ketogenic diet plan, Perfect Keto supports the four most common versions of keto:
- The Standard Ketogenic Diet (SKD): 75% fat, 20% protein, and 5% carbs
- The Targeted Ketogenic Diet (TKD): 20-50g of net carbs per day targeted around exercise and mainly used by athletes
- The Cyclical Ketogenic Diet (CKD): following the SKD most days, then adding extra carbs for a few days, then restarting the SKD
- The High Protein Ketogenic Diet (HPKD): 60% fats, 35% protein and 5% carbs
The SKD is the place to start for beginners while athletes may start out with a SKD and then shift to the HPKD to keep up with their weight lifting demands.
As for the CKD, it sounds good in theory, but it can oftentimes lead to mood swings, weight stalls and energy fluctuations so it’s not right for everyone.
PK also shares a list of keto-friendly foods to eat — without all the red zone, green zone segmentation.
The Perfect Keto Food List
The Perfect Keto team researched and identified 108 keto foods to avoid if you want to reach or remain in ketosis.
These foods will slow down (or shut down) your body’s fat burning capability, such as:
- Grains, beans and legumes
- Most fruits
- Starchy veggies
- Low-quality proteins
- Low fat or reduced fat dairy
- Raw milk in small amounts only
- Factory farmed animal products
- Unhealthy oils
- Sugary drinks, including certain alcohols
- Processed foods, artificial sweeteners and food additives
You can see a few of the PK principles overlap with Bulletproof, specifically the stance on grains, sugars, carbs, factory farmed animal products, sugary drinks, and processed foods.
They differ when it comes to fruits, starchy veggies, and raw milk.
But the biggest difference between Perfect Keto vs Bulletproof is that PK supports reaching and maintaining ketosis for as long as it’s helpful, while Bulletproof encourages you to cycle in and out of it.
Perfect Keto Encourages Staying In Ketosis
As you saw in this guide, being in a state of ketosis provides a lot of health benefits:
- Faster fat-burning
- Increased fat oxidation
- More energy
- A better mood
- Hormone regulation
- Healthy appetite suppression
- Improved insulin sensitivity (blood sugar regulation)
- Improved memory and mental focus
- Better physical performance (preventing crashes during prolonged exercises, energy maintenance, using fat for energy)
Because of this, Perfect Keto has created a growing line of clean, keto-friendly supplements and food products that help people reach and maintain ketosis so they can enjoying the health perks listed above.
This is also something PK and Bulletproof share in common.
Below you’ll see a comparison of one product both brands offer: Collagen Protein.
As you saw in this guide, collagen protein is a nutritional powerhouse.
When consumed, it can support:
- Healthy skin, hair and nails
- Muscle growth and regeneration
- Stronger bones
- Tissue repair
- Stronger eyes
- Gut health
- Heart and brain health
So it’s no wonder both Bulletproof and Perfect Keto have created their own collagen formulas.
Let’s see how they compare:
Perfect Keto vs Bulletproof Chocolate Collagen Protein Comparison
To keep things fair, this comparison will be done using 2 scoops of the chocolate collagen protein powder from each brand.
These are the nutritional facts of 2 scoops of Bulletproof chocolate collagen:
Here, you’ll notice you get:
- 170 calories, 35 of which are from fat
- 23g of protein
- 7g of net carbs
- 2g of fiber
- 4g of total fat
- 2.5g saturated fat
- Less than 1g of sugar
- Plus minerals like potassium, calcium, iron and sodium
You also get 25g of collagen.
Now let’s look at Perfect Keto Collagen.
This time, you need to double the PK serving size to equal the 2 scoops used for Bulletproof’s comparison.
That brings these stats to:
- 160 calories, 60 from fat
- 20g of protein
- 8g of fat, all from healthy saturated fats
- 2g of carbs
- Essential minerals such as iron, phosphorus, chloride, sodium and potassium
This means the Perfect Keto formula has:
- Double the fat
- Less than a third of the carbs
- More minerals than Bulletproof’s
It also has 10mg of MCTs and 20mg of grass-fed hydrolyzed collagen powder.
While the Bulletproof option has 3g more protein and 5g more collagen, the PK formula maintains a healthy 2:1 balance of collagen to MCTs — which supports ketosis — and the collagen is sourced from grass-fed cows, which are healthier.
MCTs help increase ketone levels and support gut health without raising your blood sugar.
There’s also one crucial area to pay attention to here, especially since the difference is quite drastic: the ingredient list.
Here’s what the Bulletproof ingredient list for their chocolate collagen looks like:
Now to contrast, here’s PK’s:
Kind of a big difference between brands, right?
You won’t find any artificial flavors, chemicals or ingredients in the Perfect Keto Collagen formula.
Only 100% grass-fed collagen (from USA cattle), MCT oil powder, cocoa powder and stevia leaf. That’s it.
With a better understanding of the differences between these two brands, you can probably narrow down which one may be right for you.
Bulletproof vs Perfect Keto: Find the Right Fit for Your Goals
Since Bulletproof is designed around cyclical keto, this needs to be the first area to look at when choosing between the two plans.
For new dieters on keto, the CKD route can be quite challenging and hard to follow. It could jeopardize your chances of getting back into ketosis each and every time.
You may also experience unwanted mood and energy fluctuations.
That’s why you may be better off beginning on the standard ketogenic diet and only experimenting to other types, such as cyclical, once you have reached and maintained ketosis for a period of time.
Don’t forget to always scan ingredient lists anytime you’re purchasing supplements and food product.
Since they’re not regulated by the FDA, it’s crucial you choose products free of carby fillers, artificial additives, chemicals and flavors to protect your health.
Fortunately, Perfect Keto Product Line doesn’t have any of those harmful ingredients and they’ve been specifically formulated by Dr. Anthony Gustin and his team to create cleaner, high-quality, delicious, keto-friendly products.
So now that you have all the facts on the Perfect Keto vs Bulletproof question, it’s time to figure out which approach to keto is best for you.
