Now, Week 1’s shopping list is going to be long. I have to make the assumption you have nothing in your house. Many of the items are common items that most people will have already. These are all staples in my everyday cooking for keto, and should be considered an investment for your health. Once you have all of the items from week 1, there won’t be too much else to buy.
Normal dietary fat contains mostly long-chain triglycerides (LCT). Medium-chain triglycerides are more ketogenic than LCTs because they generate more ketones per unit of energy when metabolised. Their use allows for a diet with a lower proportion of fat and a greater proportion of protein and carbohydrate,[3] leading to more food choices and larger portion sizes.[4] The original MCT diet developed by Peter Huttenlocher in the 1970s derived 60% of its calories from MCT oil.[15] Consuming that quantity of MCT oil caused abdominal cramps, diarrhoea and vomiting in some children. A figure of 45% is regarded as a balance between achieving good ketosis and minimising gastrointestinal complaints. The classical and modified MCT ketogenic diets are equally effective and differences in tolerability are not statistically significant.[9] The MCT diet is less popular in the United States; MCT oil is more expensive than other dietary fats and is not covered by insurance companies.[3]
Bulletproof Coffee is coffee with added grass-fed butter and a fat called MCT oil, which is extracted from coconut oil. It’s alright to consider it as a meal but remember that it can slightly trigger insulin. However, I think it is good to do in the beginning, as it reduces hunger. For some people, it could slow progress so it’s good to experiment.

A third study published this week in the journal PLOS Medicine that surveyed the eating habits of 471,495 Europeans over 22 years found that people whose diets had lower "nutritional quality" (i.e., fewer fresh vegetables, legumes, and nuts) were more likely to develop some of the most common and deadliest forms of cancer, including colon, stomach, lung, liver, and breast cancers.
In short, no. Apples even have too many carbs. Pineapples hugely spike insulin. Never consume fruit juices. The fiber is bound to the phytonutrients and the juice is cooked, removing many nutrients. You’re basically just drinking concentrated fructose + corn syrup. As an adult, I wouldn’t consume much fruit, period—except maybe ½ cup berries a day. Fructose consumption can lead to a fatty liver, insulin resistance and can spike insulin MORE THAN GLUCOSE!

One area where food tracking can be especially helpful, though, is ensuring that you're hitting the right ratios of macronutrients—protein, carbs, and fat. "The most researched version of the ketogenic diet derives 70 percent of calories from healthy fats, 20 percent from protein, and only 10 percent from carbs," explains Charles Passler, D.C., nutritionist, and founder of Pure Change. "In the ideal world, each keto meal and snack should have that same (70/20/10) ratio of macronutrients, but studies have shown that you'll still achieve great results even if each meal varies slightly from that ratio, just as long as you don't exceed 50 grams per day of carbs, or eat those carbs in one sitting," says Passler. In order to achieve these ratios without a preset meal plan from a dietitian or doctor, some food tracking is probably going to be necessary. But once you get the hang of things, you may not need it anymore.

These avocado bites (made only from freeze-dried avocado pieces and sea salt) are high in fat and have 7 grams of carbs per serving, making it a perfect portable keto-friendly snack. And if its low-carb appeal isn't enough, avocados are also full of fiber and potassium, she says, two nutrients that can be difficult to get enough of on the keto diet. "I recommend eating an avocado per day to most people on the keto diet, and these dried bites are a good way to help reach that goal," she says. Best part? They won't go brown like the avocado sitting on your kitchen counter.
Advocates for the diet recommend that it be seriously considered after two medications have failed, as the chance of other drugs succeeding is only 10%.[9][30][31] The diet can be considered earlier for some epilepsy and genetic syndromes where it has shown particular usefulness. These include Dravet syndrome, infantile spasms, myoclonic-astatic epilepsy and tuberous sclerosis complex.[9][32]
Which leads us to your personality. You need to be VERY strong willed to follow this diet. It follows very strict rules and you need to be able to commit to this. It makes it hard to eat out with friends or eat with friends in general. It’s hard to find food that fits this diet in common restaurants, but and this takes us to the next point, your health goals might be more important.
When you eat foods high in carbohydrates and fat, your body naturally produces glucose. Carbohydrates are the easiest thing for the body to process, and therefore it will use them first – resulting in the excess fats to be stored immediately. In turn, this causes weight gain and health problems that are associated with high fat, high carbohydrate diets (NOT keto).
