Healthy Foods for the Keto Diet: What to Eat and What to Avoid

Starting a ketogenic diet can feel confusing, especially when it comes to choosing the right foods. Keto isn’t just about eating fewer carbs — it’s about eating the right kinds of foods to support ketosis and overall health.

This guide explains which healthy foods to eat on a keto diet and which foods to avoid, so you can follow keto correctly and confidently.

What Is the Keto Diet?

The ketogenic diet is a low-carbohydrate, moderate-protein, high-fat eating plan. Its goal is to move your body into a metabolic state called ketosis, where fat is used as the primary source of energy instead of carbs.

Food choices are critical, because even small carb-heavy foods can interrupt ketosis.
