is a supplement that helps you to lose weight by putting you in Ketosis. This is exactly what the keto diet does on its own, but it's not as easy as people make it out to be. In fact, the keto diet is extremely difficult and very few people can really succeed with it. The keto diet works by removing carbs from your diet and replacing them with fats. When your body burns fats rather than carbs, you'll start to lose weight - this is how the keto diet works.
