The ketogenic diet, characterized by a high-fat, very low-carb intake, has gained immense popularity for its potential health benefits, including weight loss and improved metabolic health. When embarking on a keto journey, one of the primary considerations is carefully selecting foods that align with the diet's macronutrient requirements. This often leads to questions about the suitability of various food items, including olives. This article delves into the keto-friendliness of black olives, examining their nutritional profile, potential health benefits, and practical ways to incorporate them into your keto meal plan.
The Keto Diet: A Quick Overview
The ketogenic diet revolves around drastically reducing carbohydrate consumption and replacing it with fats. This metabolic shift forces the body to enter a state of ketosis, where it starts burning fat for fuel instead of glucose derived from carbohydrates.

With only 4.44g of net carbs per 100g serving, black olives fit comfortably within the carb limits of even a strict keto diet.
