What to eat on a keto diet: 25 foods for a low carb lifestyle

The ketogenic diet, commonly known as keto, is a dietary approach that emphasises high fat intake, moderate protein consumption, and very low carbohydrate intake. The goal of the keto diet is to induce a metabolic state called ketosis, where the body primarily relies on fat for fuel instead of carbohydrates.

What is keto diet?

Typically, a standard keto diet consists of about 70-80 percent of calories from fat, 20-25 percent from protein, and only 5-10 percent from carbohydrates. Keto diet foods bring about a drastic reduction in carbs, forcing the body to enter ketosis, a state characterised by the production of ketones from fat breakdown in the liver. Ketones serve as an alternative energy source for the body and brain when glucose (from carbohydrates) is scarce, explains dietician Garima Goyal.

The benefits of keto diet are tremendous, besides weight loss. This study, published in Nutrients, states that keto die helps with diabetes, while a study, published in Elsevier, states that it helps in the treatment of cancer as well. In fact, this study, published in International Journal of Molecular Sciences states that keto diet can help with the treatment if Alzheimer’s disease.
