Obesity is a serious global health risk, with adult death rates as high as 2.8 million per year. Obesity, which is typically the result of an unhealthy lifestyle and bad eating habits, is linked to the majority of chronic illnesses such as diabetes, hypertension, and heart disease. Appropriately designed food regimes for weight loss can aid in the management of the increase in obesity.
A extremely low-carbohydrate and high-fat ketogenic diet has been shown to be particularly effective for fast weight reduction. The ketogenic diet is a low-carbohydrate, high-fat, adequate-protein diet that is used to treat children with difficult-to-control (refractory) epilepsy. Low-carbohydrate and ketogenic diets are quite popular across the world.
Ketogenic diets are gaining popularity again. Nutritional ketosis is generally achieved by limiting carbohydrate consumption to less than 20–50 g per day, however there are exceptions. The low carbohydrate intake of these diets is generally compensated for by a high fat content, whereas protein is reasonable. As a result, the term “low-carbohydrate high-fat” (LCHF) is more suitable under isocaloric settings.
