In this guide, we’ll explore the foods you should embrace and avoid while on keto, helping you stay on track without the guesswork. Whether you’re new to keto or looking to fine-tune your meal plan, this article covers it all.
What You Can Eat on the Keto Diet
The main rule of the ketogenic diet is to minimize carbs and increase healthy fats. Your body will then enter a state called ketosis, where it burns fat for fuel instead of glucose.
Healthy Fats
Fats are your primary energy source on keto. Make sure to consume high-quality fats such as:
- Avocados and avocado oil
- Extra virgin olive oil
- Grass-fed butter or ghee
- Coconut oil and MCT oil
- Nuts and seeds (especially macadamia, almonds, chia, and flax)
Protein Sources
While keto is not a high-protein diet, moderate intake of quality protein is essential:
- Beef, chicken, turkey, and pork
- Eggs (preferably pasture-raised)
- Fish like salmon, sardines, and mackerel
- Tofu and tempeh for vegetarians
Low-Carb Vegetables
These are important for fiber, vitamins, and minerals:
- Leafy greens (spinach, kale, arugula)
- Cruciferous veggies (broccoli, cauliflower, cabbage)
- Zucchini, cucumber, bell peppers, and mushrooms

What You Can't Eat on the Keto Diet
To stay in ketosis, it's important to avoid foods that are high in carbs and sugar. Consuming these can kick you out of fat-burning mode quickly.
Sugary Foods
Foods high in sugar are a definite no on keto:
- Soft drinks and fruit juices
- Cakes, pastries, and candies
- Ice cream and sugary cereals
Grains and Starches
Even whole grains are too high in carbs for keto:
- Rice, corn, quinoa, and oats
- Bread, pasta, and tortillas
- Potatoes and sweet potatoes
High-Carb Fruits
While fruits are generally healthy, many are too carb-heavy:
- Bananas, apples, and grapes
- Mangoes, pineapples, and oranges
