Ketosis is a metabolic state that is well-known for its fat burning power. When you get on the keto diet you are eating specific foods at specific times and in different portions/macros. You see, the keto diet calls for the elimination of sugar and calories, a reduction in protein, and a massive increase in good, healthy fats. While this might sound counterintuitive, nothing could be further from the truth. In fact, fat is the most essential part of your diet when you go keto. Ultimately an increase in your good fats will kick your body into ketosis where it burns fat for energy instead of sugar.
