A ketogenic or keto diet involves eating foods low in carbohydrates but high in fat. This combination prompts production of the ketone beta-hydroxybutyrate (BHB). If the body lacks glucose, it taps into fat stores for energy in a process called ketosis. Many celebrities live on a ketogenic diet because it can assist with weight loss, control blood sugar, and may help ward off diseases such as Alzheimer’s.
1. Fish and Seafood
Salmon, sardines, and mackerel are healthy brain foods because they are rich in omega-3 fatty acids. Salmon is also packed with potassium, selenium, and B vitamins, and has zero carbohydrates. While shrimp and some crab also lack carbs, some shellfish do contain this nutrient, which is strictly avoided on the keto diet. Clams, oysters, squid, and other seafood are keto-friendly. Eat at least two servings of seafood a week for a healthy amount of vitamins, minerals, and omega-3s.
