When your body is in the metabolic state of ketosis, it turns fat into ketones in the liver, which will supply energy instead of glucose, as if you were fasting. You may have heard of the ketogenic diet, in fact, which focuses on protein and fat intake, while maintaining a very low carbohydrate intake. This diet, newly trendy, may have benefits such as weight loss and improved blood sugar levels. However, it is very restrictive; eliminating healthy fruits, vegetables, legumes, and other nutritious complex carbohydrates seems unnecessary and no fun. Also, we don’t know the long-term effects of ketosis (though if you do go too long without any carbs, it can lead to heart or kidney disease). What I do know, after years of studying nutrition, is that any diet that is very restrictive or eliminates entire food groups can be unrealistic and difficult to sustain. That’s why Zero Sugar Diet eliminates added sugars—but allows natural ones. Pretty sweet deal.”” [David Zinczenko](https://sms4smile.com/quotes/author/david-zinczenko/) ## About This Quote This interpretation was drafted with AI assistance. It is one reading of the quote, not the author's own explanation. Very low‑carb diets like keto can aid weight loss but often exclude essential nutrients and have uncertain long‑term health impacts. **In simple terms:** Keto helps weight loss but may lack nutrients.
