The keto diet involves having a high-fat and very low-carb diet. The carbohydrate quantity depends on each person. They could range between 20g-50g of carbs per day for a very low carb content to 50-130g per day for mild carb content. It is challenging to keep the body in ketosis; even just eating a small number of carbs, e.g., a piece of fruit, could bring someone out of ketosis.
The keto diet is often very high in saturated fat and low in fruits, vegetables, and whole grains - all associated with reducing cardiovascular disease and bowel cancer and increased risk for early death.
It’s essential you choose suitable fat sources. Aim to consume unsaturated fats mainly, with saturated fats kept to a minimum.
The keto diet is incredibly restrictive and should not be used long-term. Dramatically reducing a food group that should be 50-60% of our intake can have health implications. Carbohydrates are nutritious and rich in fiber, an essential dietary component for longevity.
