What Truly Sets These Meal Plans Apart is that They’re Based on the Keto Diet

A keto diet is an eating style where you consume almost no carbs, moderate amounts of protein, and high amounts of dietary fat. So, you’ll be eating tasty high-fat meals like ribeye steak with roasted garlic and butter. “Why would you do that?” you may wonder. Well, a very low carb intake puts you into a state called “ketosis.” You see, under regular circumstances, your body relies for the most part on glucose (the stored form of carb).

When you minimize your carb intake, however, there's not enough glucose available for your body to fuel all its functions. And because some tissues like your brain cannot use fat for fuel, your body needs an alternative energy source to stay alive. That’s where ketones come in.

Ketones are chemicals produced in your liver when glucose is scarce. Various tissues like your brain can use these ketones for fuel when glucose is absent. That's an excellent outcome because, otherwise, you would die. Now, when your body uses primarily ketones and fatty acids for fuel, you're in a state called “ketosis.”
