The ketogenic diet, also known as the keto diet, is one that is high in protein and fats, but very low in carbohydrates. The keto diet is ideal for people looking to lose weight since minimal carbohydrate consumption can lead to significant reductions in blood sugar and insulin levels. With the lessened carbohydrate load, the body will go into a state of ketosis and burn excess fats efficiently.
Some people on the keto diet count their total carbohydrate intake, others focus on counting the net carbs instead – total carbs excluding fibre intake since fibre cannot be digested and absorbed by the body. While the keto diet may seem challenging for some, it allows people following it to eat many high-nutrient foods.
Unlike the other high-protein diets, the keto diet is about consuming enough fats, making it easy for one to indulge in many delicious foods with saturated fats and skimp on the healthy stuff. However, the downside to this is that eating huge amounts of saturated fats is not healthy, even though it is considered as "keto-friendly." You still need to consume sufficient unsaturated fats, fibre, and protein to balance it all out. Aside from dairy products and red meat, seafood is also an excellent food choice for keto diets. In general, seafood contains very low amounts of carbohydrates, thus, it is naturally keto-friendly. Other types of seafood like shrimp and crab are almost fat-free, whereas salmon, mackerel, and cod contain high amounts of heart-healthy unsaturated fats such as Omega-3s.
