What is a Ketogenic Diet?

The ketogenic diet is a way of eating that’s high in fat and low in carbs. It aims to put your body in a state called ketosis. In ketosis, your body uses fat and ketones for energy instead of glucose. This change may help with losing weight and controlling blood sugar.

Understanding the Basics of Keto

For the ketogenic diet to work, you need to eat the right amounts of macronutrients. The usual ratios are:

  • Carbs: 5-10%
  • Fats: 70-75%
  • Protein: 15-20%

These numbers help your body burn fat and ketones rather than carbs for energy. By eating few carbs, your body enters ketosis. This might bring several health benefits.

Macronutrient Ratios in a Keto Diet

Success on the keto diet means sticking to the right macros. You should aim for a very low carb, high fat, and moderate protein diet. This translates to only 5-10% of your daily calories from carbs, 70-75% from fats, and 15-20% from proteins. These ratios help your body switch to using fat for energy, instead of carbs.

On the keto diet, you’ll eat foods rich in fats and low in carbs. This includes meat, fish, eggs, dairy, nuts, seeds, and specific vegetables. Choosing from this list lets you prepare meals that are good for your health and can help with managing your weight.
