I get this question every day. I can see why people are curious. Between my husband and I, we’ve lost 35 lbs in our first month on the ketogenic diet.
Ruled.me is a great source, and answers this question more thoroughly than I can:
“A keto diet is well known for being a low carb diet, where the body produces ketones in the liver to be used as energy. It’s referred to as many different names – ketogenic diet, low carb diet, low carb high fat (LCHF), etc.”
Usually your body will use Glucose (from carbs and sugar) for energy. Putting your body into a state of Ketosis retrains the body to use fat for energy in place of glucose, turning you into a 24 hour fat-burning machine!
Keto is not for everyone. Consider speaking with your doctor before starting any diet, especially if you have any chronic health issues.
