Keto Macro Calculator
The ketogenic diet requires precise macronutrient ratios to achieve and maintain ketosis. This calculator determines your optimal daily intake of fat, protein, and net carbohydrates based on your personal stats and weight management goals.
The ketogenic diet is a high-fat, moderate-protein, very-low-carbohydrate diet that shifts the body from burning glucose to burning fat (and ketones) for energy. The standard keto macronutrient ratio is approximately 70% fat, 25% protein, and 5% carbohydrates. This typically translates to 20-50 grams of net carbs per day.
Maintaining this precise ratio is critical for achieving nutritional ketosis, a metabolic state where blood ketone levels reach 0.5-3.0 mmol/L. Eating too many carbohydrates will prevent ketosis, while eating too much protein can also interfere through gluconeogenesis (the conversion of amino acids to glucose).
The keto diet has shown benefits for weight loss, blood sugar control, and certain neurological conditions. However, it requires careful planning to ensure adequate micronutrient intake and may not be appropriate for everyone. Common concerns include the "keto flu" during adaptation (first 1-2 weeks), potential impacts on kidney function with very high protein intake, and the sustainability of strict carb restriction. Consult a healthcare provider or registered dietitian before starting a ketogenic diet.
