By loading up on eggs, avocados, and other high-fat, low-carb foods, you can live healthier while losing weight on a sustainable basis! The key is achieving ketosis. But, don’t get scared of the term, as you will find out that ketosis is a good thing! Your body can take only two forms of energy. Either it uses up the sugar in your bloodstream or it takes in fat in the form of chemical compounds produced by your liver called ketones. When people achieve ketosis, they not only lose weight, but they get a nice burst of energy; they think more clearly; their skin improves and a whole long list of tremendous health benefits.
