For both keto and Bulletproof diets, opt for full-fat, grass-fed, raw, and organic dairy to reap the anti-inflammatory benefits of omega-3s and CLA. Dairy is a great source of fat on a ketogenic diet, but be mindful not over-do the protein. Although milk (yep, even raw, full-fat, or goat milk) is too high in lactose sugars, you can stay in ketosis with foods like butter, ghee, and colostrum. Avoid sweetened or low-fat dairy, evaporated or condensed milk, and buttermilk to keep your fat intake high.

Beyond being high in healthy fats, research has shown that people who include nuts in their diet are likely to live longer than those who don't. The right type of nut can be a great keto-friendly snack. The thing to remember with the keto diet is that you're looking specifically for low-carb, high-fat foods. Certain nuts meet this criterion and should be included in your keto meal plan in moderation. Listed in order of lowest to highest carb content per 1-ounce serving, the best nuts for the keto diet include:

The keto diet isn’t new, and it’s been around for nearly a century. It was originally developed to treat people with epilepsy. In the 1920s, researchers found that raised levels of ketones in the blood led to fewer epileptic seizures in patients. The keto diet is still used today to treat children with epilepsy who don’t respond well to anti-epileptic drugs.[2]
This low-carb chicken pad thai is one of the best keto recipes for replacing Asian takeout. It’s got all of the flavors that come with normal pad thai, like ginger, crushed peanuts, tamari and chicken, but all served up on spiralized zucchini instead of carb-heavy noodles. Best of all, you’ll have this keto chicken recipe on the table in just 30 minutes.

Ketosis takes some time to get into – about two weeks of low carb eating is required for the initial adaptation. During this time there will be bouts of sluggishness, fatigue, headaches, and some gastrointestinal issues as you adapt, often referred to as “keto flu“. Proper electrolyte intake will correct most of these issues. In addition, the “diet” aspect of this ketogenic diet plan – that is, the caloric restriction – shouldn’t be worried about. Weight loss will come as your body regulates appetite as it the addiction to sugar and processed food lessens, so restricting calories during the initial two weeks isn’t recommended.
I know it may be challenging to follow a healthy low-carb diet, especially if you are new to it. I hope this comprehensive list of keto-friendly foods will help you make the right choices, whether your goal is to lose weight or manage a health condition such as type 2 diabetes, insulin resistance, Parkinson’s, Alzheimer’s, epilepsy and even cancer.
Potatoes and gravy are total comfort food — and luckily, there’s a keto version. These are made with cauliflower, which is quite low-carb, particularly when compared to potatoes. Made with cream, butter, rosemary and parmesan, this mash is creamy, full of flavor and smooth. You’ll finish it all off with a stock-based gravy, that would be perfect on a roast, too.

On the ketogenic diet, carbohydrates are restricted and so cannot provide for all the metabolic needs of the body. Instead, fatty acids are used as the major source of fuel. These are used through fatty-acid oxidation in the cell's mitochondria (the energy-producing parts of the cell). Humans can convert some amino acids into glucose by a process called gluconeogenesis, but cannot do this by using fatty acids.[57] Since amino acids are needed to make proteins, which are essential for growth and repair of body tissues, these cannot be used only to produce glucose. This could pose a problem for the brain, since it is normally fuelled solely by glucose, and most fatty acids do not cross the blood–brain barrier. However, the liver can use long-chain fatty acids to synthesise the three ketone bodies β-hydroxybutyrate, acetoacetate and acetone. These ketone bodies enter the brain and partially substitute for blood glucose as a source of energy.[56]
Wondering what fits into a keto diet — and what doesn’t? “It’s so important to know what foods you’ll be eating before you start, and how to incorporate more fats into your diet,” says Kristen Mancinelli, RD, author of The Ketogenic Diet: A Scientifically Proven Approach to Fast, Healthy Weight Loss, who is based in New York City. We asked her for some guidelines.
Maya, I think what you are doing is brilliant. I am a 70-year old professional woman, educator and coach. I’ve grown our family vegetables every summer since I can remember. However, health conscious 20 or 30 years ago is a far different scenario today. Until I started having digestive issues about 5 years ago, I figured I was in the “above average” category of healthy eating.

Infants and patients fed via a gastrostomy tube can also be given a ketogenic diet. Parents make up a prescribed powdered formula, such as KetoCal, into a liquid feed.[19] Gastrostomy feeding avoids any issues with palatability, and bottle-fed infants readily accept the ketogenic formula.[31] Some studies have found this liquid feed to be more efficacious and associated with lower total cholesterol than a solid ketogenic diet.[18] KetoCal is a nutritionally complete food containing milk protein and is supplemented with amino acids, fat, carbohydrate, vitamins, minerals and trace elements. It is used to administer the 4:1 ratio classic ketogenic diet in children over one year. The formula is available in both 3:1 and 4:1 ratios, either unflavoured or in an artificially sweetened vanilla flavour and is suitable for tube or oral feeding.[51] Other formula products include KetoVolve[52] and Ketonia.[53] Alternatively, a liquid ketogenic diet may be produced by combining Ross Carbohydrate Free soy formula with Microlipid and Polycose.[53]
Mainly for health reasons, avoid soy products apart from a few non-GMO fermented products which are known for their health benefits. Also avoid wheat gluten which may be used in low-carb foods. When you give up bread, you shouldn't eat any part of it. Beware of BPA-lined cans. If possible, use naturally BPA-free packaging like glass jars or make your own ingredients such as ghee, ketchup, coconut milk or mayonnaise. BPA has been linked to many negative health effects such as impaired thyroid function and cancer. Other additives to avoid: carrageenan (e.g. almond milk products), MSG (e.g. in some whey protein products) and sulfites (e.g. in dried fruits, gelatin).
This is one area where full keto and Bulletproof differ. Except for coconut, all nuts and legumes are suspect on the Bulletproof Diet and should be limited. All expose you to high amounts of omega-6s, inflammatory oxidized fats, mold toxins, and phytates (plant anti-nutrients). Peanuts are one of the main sources of mold toxins in our diets, and often trigger allergic responses with inflammatory polyunsaturated fats, lectins and histamines. The Bulletproof Diet also excludes all soy products due to their phytoestrogen content, which messes with your hormones and may promote cancer.

While vegetables are not particularly high in fat, many are quite low in carbs, and any healthy diet must include these vitamin- and mineral-rich staples. Roasted, steamed, or raw, you can't go wrong with low-carb veggies in a keto meal plan. Listed in order of lowest to highest carb content per raw 1-ounce serving, the best vegetables for the keto diet include:
The keto diet also appears to help induce autophagy, which helps clear damaged cells from the body, including senescent cells that serve no functional purpose but still linger inside tissues and organs. In animal studies when rats are put on the ketogenic diet, autophagic pathways are created that reduce brain injury during and after seizures. (21)
Carbs in fruits and veggies do count, but you don’t add up the carbs and sugar. Sugar is already included in the carbs – it’s just listed separately on labels because some people want to see a breakdown of how much of the carbs are sugars (versus other, complex carbs). If it says 2g carbs and 2g sugar, it means there is 2g total carbs and all of them are sugar (in this case).
It prompts the question: why is this incredibly challenging, rigid, expensive diet so popular? One answer is the “modern caveman” narrative, as strong among keto advocates as it was with its paleo predecessor. This speaks to the compelling, but misplaced, notion that illness is simply a result of modern food processing practices and lifestyles, and can be reversed by returning to a simpler time. But a diet is a diet is a diet, and they all work the same way – by reducing the net amount of energy consumed. Keto diets may have a slight advantage, as the high fat intake is hypothesised to have satiating properties, helping you stay fuller for longer. But in reality, we have little evidence to show that keto is more effective in the long run than any other diet – or, indeed, that any diet succeeds in keeping off weight.
The fear, of course, is that many people don’t seek out information and support from regulated healthcare professionals before making major changes to their diet. Most newcomers are drawn to keto for its potential weight-loss benefits, and, while it remains a topic of debate among nutritional scientists, its proponents typically gloss over the unknowns. Keto advocates claim it gives them an edge for athletic performance by turning them into fat-burning machines.
Just because keto is a high fat diet doesn't mean you should rely on large portions of fatty meats to hit your daily fat quota. “It’s not about eating an 8-ounce steak,” Mancinelli says. “Instead, have a 3-ounce portion of steak with half an avocado on the side.” That’ll help you meet your fat needs without overdoing it on the protein or potentially harmful saturated fats.
If you’ve decided to move forward in trying the keto diet, you will want to stick to the parameters of the eating plan. Roughly 60 to 80 percent of your calories will come from fats. That means you’ll eat meats, fats, and oils, and a very limited amount of nonstarchy vegetables, she says. (This is different from a traditional low-carb diet, as even fewer carbs are allowed on the keto diet.)
Tea and coffee, including Bulletproof Coffee, are completely ketogenic, with bonus points for jump-starting weight loss and focusing your mental clarity. Watch out for sweeteners, fillers, or artificial flavors. While you can drink unsweetened, plant-based milk alternatives in moderation without going out of ketosis, they are not Bulletproof, and are usually loaded with toxic molds — the exception being full-fat coconut milk.[4] If you plan to include them in your diet, beware of carrageenan and BPA-lined containers. 

What makes this diet so special is that it changes how your body feels and most importantly how your body uses energy, placing you into a state known as ketosis. This is actually where all the magic begins to happen; in this state your body starts to utilize substances known as ketone bodies which are produced by the breakdown of your body fats. Your body loves glucose and if it has that on hand it’s going to use that first for energy. On the keto diet, the amount of carbohydrates decreases drastically, which in turn will lead to less production of glucose. High levels of glucose production is generally what makes you fat; without it, the body will begin to start breaking down your body fat and this is when you start to get leaner.
You should aim to score your carbs from high-fiber, water-rich fruits and vegetables to naturally boost hydration and keep your digestive system humming along. Unsure of whether a produce pick is low in carbs? Reach for options grown above the ground (leafy greens, peppers, and stalk-shaped vegetables), rather than below ground (root veggies like potatoes, carrots, and parsnips), as they typically offer fewer carbs.
Carol- so sorry to hear about your stroke. I am not sure most doctors would approve of this diet due to most not being taught much on nutrition in med school, and most still believe in the old school high carb low fat way of eating. My experience has been a dramatic drop in my blood pressure in only a few weeks after starting this diet (172/105 down to 144/95!). I suggest giving it a trial of a few months to see how it may work for you.

Although the exact role of the keto diet in mental and brain disorders is unclear, there has been proof of its efficacy in patients with schizophrenia. And, to boot, it works to reverse many conditions that develop as a side effect of conventional medications for brain disorders, like weight gain, type 2 diabetes and cardiovascular risks. More research is needed to understand the role of the ketogenic diet in treating or improving schizophrenia, as the current available studies are either animal studies or case studies, but the benefits of a low carbohydrate, high-fat diet in neurology is promising.


It seems like everyone is talking about the keto diet — the high-fat, low-carb eating plan that promises to turn your body into a fat-burning machine. For that reason, keto has surged in popularity over the past year as a lose-weight-fast strategy. Thank Hollywood A-listers and professional athletes like Halle Berry, Adriana Lima, and Tim Tebow who’ve publicly touted the diet’s benefits, from shedding weight to slowing down aging. Here’s everything you need to know about going keto.
