Zero Dependencies ยท Works OfflineThe Ketogenic Diet is a very low-carb, high-fat, moderate-protein eating approach. By drastically reducing carbohydrate intake (typically <50g/day), the body enters a state of "ketosis," switching to burning fat and producing ketones as its primary energy source.
For most healthy individuals, the ketogenic diet is safe in the short to medium term (3-6 months). People with liver, pancreas, or gallbladder conditions, and pregnant/breastfeeding women should consult a doctor first. Regular blood work to monitor lipids is recommended.
Keto flu is the transitional symptom when your body switches from burning carbs to burning fat, typically lasting 3-7 days. Symptoms include headache, fatigue, and irritability. Electrolyte supplementation and adequate hydration can alleviate symptoms.
While keto's primary focus is carb restriction, you still need a calorie deficit for fat loss. This calculator helps you find the right calorie target within the keto framework.
Standard keto recommends <50g net carbs daily (net carbs = total carbs - fiber). Some people may need <20g to enter ketosis. This calculator automatically computes carbs at 5% of total calories.
