If you want to fight obesity, then nutritional ketosis can help you a lot. Many researches confirmed that ketogenic diet can change your metabolic engine from burning carbohydrates to burning fats. This requires 50-70% of your food intake coming from the beneficial fats like coconut oil, organic pastured eggs, avocado, grass-pastured butter, macadamia nuts, and pecans.
The carbs are in small amount and in this way the body burns fat for energy, meaning that there is little sugar in the system which blocks the body from utilizing fat in favor of burning sugar. The body produces ketones that are made from fats processed in the liver.
