For anyone, regardless of any underlying health issues, the so-called keto flu is a possibility (and even likelihood) as your body adjusts to ketosis on the keto diet, says Tori Schmitt, RDN, founder of YES! Nutrition, LLC based in Dayton, Ohio. Fatigue, irritability, headaches, and nausea are all symptoms of the keto flu, Schmitt says. Fortunately, keto flu lasts only about one to two weeks.
The name "ketogenic" comes from ketosis. At its most basic level, ketosis is the body's process of turning fat into energy. When your body's carbohydrate stores are low, you convert stored fat into ketones, which supply energy to the body. A ketogenic diet stresses the consumption of natural fats and protein—such as meat, fish, and poultry—while limiting carbohydrates. This maintains ketosis over a sustained period of time.
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.
As any ketogenic dieter knows, the lifestyle requires a lot of diligence. Even snacking on a banana could ruin your diet. The main goal of keto is to use fat instead of carbohydrates for energy, a process known as ketosis. Generally, keto dieters eat lots of fat, a moderate amount of protein, and just 20-30 grams of carbohydrates per day to maintain ketosis. For context, that's about half a medium bagel.
