Keto Calculator
Calculate your personalized ketogenic diet macros to achieve your health goals. This calculator determines your ideal daily calorie intake and provides precise fat, protein, and carbohydrate targets following the standard keto ratio of 70% fat, 25% protein, and 5% carbs.
• Fat: 70-75% of daily calories
• Protein: 20-25% of daily calories
• Carbs: 5-10% of daily calories (20-50g max)
Calorie Conversion:
• Fat: 1g = 9 calories
• Protein: 1g = 4 calories
• Carbs: 1g = 4 calories
Fat (70%): 1400 cal ÷ 9 = 156g
Protein (25%): 500 cal ÷ 4 = 125g
Carbs (5%): 100 cal ÷ 4 = 25g
Daily totals:
156g fat, 125g protein, 25g carbs
What is a keto diet and how does it work?
A ketogenic (keto) diet is a high-fat, moderate-protein, and very low-carbohydrate diet. Typically, it consists of 70-75% fat, 20-25% protein, and only 5-10% carbohydrates. By drastically reducing carbs (usually to 20-50g net carbs per day), your body enters a metabolic state called ketosis, where it burns fat for fuel instead of glucose. This shift can lead to weight loss, improved energy levels, and better mental clarity for many people.
How many carbs can I eat on a keto diet?
Most people need to limit net carbs to 20-50 grams per day to maintain ketosis. Net carbs are calculated by subtracting fiber from total carbohydrates. Beginners should aim for the lower end (20-30g) to ensure they enter ketosis. Your exact carb limit depends on factors like activity level, metabolism, and goals. This calculator provides a personalized recommendation based on your daily calorie needs.
How much protein should I eat on keto?
Protein intake on keto should be moderate, typically 20-25% of total calories or about 0.6-1.0 grams per pound of lean body mass. Too little protein can lead to muscle loss, while too much can potentially interfere with ketosis through a process called gluconeogenesis. For most people, this translates to 70-120 grams per day. Athletes and highly active individuals may need more protein to support muscle maintenance and recovery.
What are the best fat sources for a keto diet?
Healthy fat sources for keto include avocados, olive oil, coconut oil, butter, ghee, nuts (almonds, macadamias, walnuts), seeds (chia, flax, hemp), fatty fish (salmon, sardines, mackerel), and full-fat dairy. Focus on unsaturated fats from whole food sources and omega-3 fatty acids. Avoid trans fats and limit processed vegetable oils. Since fat makes up 70-75% of your calories on keto, choosing quality sources is essential for both health and satiety.
