Frequently Asked Questions
What is the keto diet?
The ketogenic (keto) diet is a high-fat, moderate-protein, very-low-carb diet. By drastically reducing carbs (typically under 20-50g/day), your body enters ketosis and burns fat for fuel instead of glucose.
Why is fat so high on keto?
On keto, fat replaces carbohydrates as your primary energy source. The 70% fat target ensures you have enough energy while keeping carbs low enough for ketosis.
How many carbs can I eat on keto?
Most people need to stay under 20-50g of net carbs per day to maintain ketosis. Net carbs = total carbs minus fiber. Start at 20g and adjust based on your results.
