Many people use these terms interchangeably, but the diets differ quite a bit in their metabolism. The main goal of a keto diet is to get your body into a keto-adapted state known as "ketosis." Keto-adaptation refers to the body's ability to use ketones-small lipid-derived molecules produced in the liver-and fatty acids instead of glucose as its primary energy sources. What are the Athletic Benefits of Being Keto-Adapted? I wasn’t sure how well being a runner would work with being a vegetarian, so I’m really happy that I found your website and found that it is possible to be an athlete and a vegetarian too. The average human can only store about 2,000 kcals of glycogen but can store well over 25,000 kcals of fat.

Half of the tortilla dough will fit on a length of parchment the size of a half-sheet pan (this is the one I use) when rolled thinly, but you’ll need to split up the chips into two sheet pans to bake or they won’t crisp up nicely.
