The ketogenic diet, commonly known as the keto diet, is a low-carbohydrate eating plan that has gained popularity for its potential health benefits and weight loss effects. When following a keto diet, individuals are instructed to limit their carbohydrate intake to less than 50 grams per day, with some variations suggesting an even lower threshold of 20 grams. This restrictive approach to eating promotes a state of ketosis, where the body primarily relies on fat for fuel instead of carbohydrates. While the focus is mainly on consuming high amounts of healthy fats, it is important to understand which fruits can be included in a keto diet and their associated benefits and risks.
What Is the Keto Diet?
The keto diet is not just a low-carb diet; it is also high in fat. This eating plan has been used since the 19th century and has been shown to be effective in weight loss, diabetes management, and even the treatment of certain medical conditions like epilepsy, migraines, and psychiatric disorders. The diet’s ability to induce ketosis, a metabolic state in which the body burns fat for energy, has led to its exploration for other health conditions such as cancer, polycystic ovary syndrome (PCOS), and Alzheimer’s disease.
Keto-Friendly Fruits
While the keto diet restricts the consumption of many fruits due to their higher carbohydrate and sugar content, there are still several fruits that can be included in a keto meal plan. These fruits are low in carbohydrates and sugar, making them suitable options for individuals following a keto diet.
