The Bulletproof Diet is a restrictive form of the keto diet, focusing on high-fat, low-carb, and moderate-protein intake. It involves intermittent fasting and higher-carb intake on one to two days per week. The diet recommends eating between 30-50 grams of net carbs daily for six days, followed by a carb refeed day with 150-300 grams of net carbs. The goal is to promote ketosis, stabilize blood sugar, enhance weight loss, and improve cognitive function. While the Bulletproof Diet may lead to initial weight loss, it is not considered a healthy long-term method due to its restrictive nature.

What You'll Learn
The Bulletproof Diet is a variation of cyclical keto
The Bulletproof Diet is a more restrictive form of the keto diet. It is a low-carb diet that focuses on food quality and limiting your carb intake. It is similar to a cyclical ketogenic diet, but with specific guidelines. The diet encourages eating high-quality fats, like avocados, coconut oil, and grass-fed butter or ghee, and limits carbohydrates to low-glycemic vegetables and minimal fruits. It also incorporates intermittent fasting as an optional component.
On the Bulletproof Diet, you follow a keto-like diet for five to six days of the week, which is high in fat, moderate in protein, and very low in carbohydrates. The remaining one to two days are "carb refeed" days, where you consume around 300 grams of carbs. The diet is very specific about the foods you can and cannot eat, labelling them as "bulletproof" or "toxic".
The Bulletproof Diet is not backed by science and has been criticised by doctors and nutritionists. It may lead to temporary weight loss, but it is not considered a healthy method. It is important to note that the keto diet itself has been around since the 1920s and was developed by physicians to treat epilepsy in children.

It involves eating minimal carbs and using quality fats for fuel
The Bulletproof Diet is a more restrictive form of the keto diet. It involves eating minimal carbs and using quality fats for fuel. This means that you can eat high-fat, very-low-carb foods six days a week, and then have a carb refeed on the seventh day. This is because regularly consuming carbohydrates (especially sugar) can lead to energy crashes and minor mood swings.
On the Bulletproof Diet, you can eat up to 50 grams of net carbs per day for six days a week. On the seventh day, you can eat up to 150 grams of net carbs. Net carbs are those that remain after you subtract the fibre and sugar alcohols (like xylitol) from your daily carb count. These don't affect your blood sugar or get stored as glycogen.
The Bulletproof Diet recommends eating healthy fats like avocados, coconut oil, grass-fed butter or ghee, and MCT oil. It also suggests eating low-glycemic vegetables and minimal fruit. The diet aims to stabilize blood sugar levels, promote weight loss, and support cognitive function.
The Bulletproof Diet is not just about what you eat, but also when you eat. It incorporates intermittent fasting, which helps your body enter ketosis faster. Ketosis is a metabolic state where your body burns fat instead of carbs for fuel, providing several benefits, including more energy and fewer cravings.
The Bulletproof Diet is very specific about the types of food you can eat, labelling them as "bulletproof" or "toxic". It prioritises organic, grass-fed, and non-GMO foods to minimise exposure to contaminants. It also recommends only eating organic produce and grass-fed meats.

It's recommended to eat \<50g net carbs daily
The Bulletproof Diet is a more restrictive form of the keto diet, focusing on high-fat, moderate-protein, and very low-carb food consumption. It is based on the idea that eating minimal carbs and using quality fats for fuel will induce ketosis, a metabolic state where the body burns fat for fuel. This approach is said to provide several benefits, including more energy and fewer cravings.
To achieve ketosis, it is recommended to limit daily net carb intake to less than 50 grams. Net carbs refer to the total carbohydrate content of food minus fibre and sugar alcohols, which do not significantly impact blood sugar or glycogen storage. By reducing simple carbs, such as sugary foods, refined grains, and starchy vegetables, individuals can lower their blood glucose levels and stabilise energy.
For those adhering to the Bulletproof Diet, consuming 5-8 servings of green vegetables can provide the recommended daily net carb allowance while leaving limited room for starches like rice or sweet potatoes. This approach prioritises healthy fats, such as avocados, coconut oil, grass-fed butter, and MCT oil, to promote satiety and sustain energy levels.
While the recommendation of less than 50 grams of net carbs daily is a general guideline, it is important to note that individual needs may vary. Some people may benefit from slightly higher carb intake, especially if they are athletes or have certain medical conditions. It is always advisable to consult with a healthcare professional before starting a new diet, particularly one that significantly restricts carbohydrate consumption.

The diet includes intermittent fasting
The Bulletproof Diet is a more restrictive form of the keto diet. It involves eating a high-fat, moderate-protein, and very low-carb diet for five to six days of the week, and then having one to two "carb refeed" days. The diet also incorporates intermittent fasting.
Intermittent fasting involves restricting your eating to a specific time period. During this eating window, you can have two meals, such as lunch and dinner. Outside of this window, you fast. Intermittent fasting can be combined with any type of diet, but it is particularly popular with low-carb, high-fat diets like keto and Bulletproof. This is because intermittent fasting supports ketosis, the metabolic state where the body burns fat for fuel.
There are several benefits to intermittent fasting. Firstly, it can help with weight loss, as it is an easy way to control the amount of food you eat. It can also boost brain health and lower your risk of neurodegenerative diseases such as Alzheimer's and Parkinson's. Intermittent fasting has also been shown to promote autophagy, the process where the body clears out cellular debris so that cells can work more effectively. In addition, a 2003 study found that intermittent fasting helped protect neurons in the brain from excitotoxic stress (neuronal death). Finally, intermittent fasting can improve quality of life and decrease fatigue.
However, there are some downsides to intermittent fasting. One of the most common side effects is hunger, especially when fasting for prolonged periods. It can also be a mental challenge to change your eating schedule, and it may not be suitable for everyone. Before starting an intermittent fasting schedule, it is important to consult with a healthcare professional.

It's a restrictive diet that may not be considered a healthy method of weight loss
The Bulletproof Diet is a restrictive form of the keto diet, with a focus on high-fat, moderate-protein, and very low-carbohydrate intake. It involves starting each day with a cup of Bulletproof Coffee, made with grass-fed butter or ghee and medium-chain triglyceride (MCT) oil. This is followed by five to six days of a keto-like diet, and one to two days of "carb refeed" with 300 grams of carbs. The diet is very specific about which foods are allowed and not allowed, recommending only organic produce and grass-fed meats.
While the Bulletproof Diet may lead to weight loss, it is not considered a healthy method. Roxana Ehsani, a sports nutritionist, notes that it is a "fad diet that restricts and cuts out major food groups to shed weight quickly". The weight loss may be temporary, and the moment carbohydrates are consumed again, the weight may return. The diet includes intermittent fasting, but does not provide specific guidelines on how much one should fast, making it restrictive and hard to follow.
The Bulletproof Diet is also more restrictive than the keto diet, cutting out specific foods that are not off-limits on keto. Ehsani further states that neither diet provides long-term health benefits. The Bulletproof Diet lacks scientific backing, and no studies have been conducted on it.
The diet is extremely particular about the foods one can and cannot eat, labelling them as "bulletproof" or "toxic". It emphasizes organic, grass-fed, and non-GMO foods to minimize toxins and maximize nutrient intake. It also encourages the elimination of grains and gluten, which can contribute to inflammation and interfere with nutrient absorption.
The Bulletproof Diet may not be suitable for everyone, and it is important to consult with a healthcare professional before starting any new diet, especially one as restrictive as this. While it may lead to weight loss, it may not be sustainable or healthy in the long term.

Frequently asked questions
The Bulletproof Diet is a more restrictive form of the keto diet. It involves eating foods high in fat, moderate in protein, and very low in carbohydrates. It also incorporates intermittent fasting and higher carb intake on one to two days of the week.
The recommended carb intake for the Bulletproof Diet is generally low, with a focus on healthy fats and low-glycemic carbohydrates. Most people do best eating between 30-150 grams of net carbs daily. On a standard keto diet, this could be around 20-50 grams of net carbs per day.
Some people may experience better mental clarity and focus by choosing foods that support health and are low in toxins. The low-carb approach can also promote ketosis, a metabolic state where the body burns fat for fuel, which can lead to weight loss.
The Bulletproof Diet is not backed by science and is considered a fad diet that restricts and cuts out major food groups. It may not be a healthy method of weight loss, and the weight loss may not be sustained. Additionally, the intermittent fasting component lacks specific guidelines, making it restrictive and potentially unrealistic.
Some alternatives to the Bulletproof Diet include the standard keto diet, the paleo diet, and the vegetarian keto diet. These diets also emphasize healthy fats and low-carbohydrate intake but may offer more flexibility in food choices and macronutrient ratios.
