The ketogenic diet has gained popularity as a low-carbohydrate, high-fat dietary approach that aims to shift your body into ketosis—a metabolic state where you burn fat for fuel instead of carbohydrates. For those starting this diet, knowing which foods fit the plan is critical for success.
Understanding Keto Diet Basics
The standard ketogenic diet typically includes:
- 70-80% calories from fat
- 15-25% calories from protein
- 5-10% calories from carbohydrates
This usually means limiting carb intake to 20-50 grams per day, depending on individual factors like activity level and metabolism.

Nutritional Considerations
While following keto, pay attention to:

Final Thoughts
The ketogenic diet restricts many common foods but still offers plenty of delicious options. By focusing on natural fats, quality proteins, and non-starchy vegetables, you can create satisfying meals while maintaining ketosis.
Starting keto requires learning new cooking approaches and food choices, but many find the adjustment period leads to sustainable eating patterns. Keep this food list handy when shopping, meal planning, and dining out to help maintain your ketogenic lifestyle.
Remember that individual carbohydrate tolerance varies, so you may need to adjust your specific food choices to maintain ketosis based on your body’s response. Tracking your macros initially can help you learn which foods work best for your personal keto journey.
