Keto-Friendly Foods: What to Eat and What to Avoid

The ketogenic diet revolves around consuming low-carbohydrate, high-fat foods to push the body into ketosis, a metabolic state where fat becomes the primary energy source instead of glucose. Following the right food choices is essential for staying in ketosis and maximizing the diet’s benefits, including weight loss, stable blood sugar, and increased energy.

Not all foods fit into a keto-friendly lifestyle. While some support ketosis and overall health, others can spike blood sugar, disrupt fat burning, and hinder progress. Understanding which foods to include and which to avoid ensures a smoother transition into ketosis and better long-term results.

Keto-Friendly Foods to Eat

A well-balanced keto diet consists of healthy fats, moderate protein, and low-carb vegetables while limiting high-carb and processed foods.
