Frequently Asked Questions

What is the ketogenic diet?+
The keto diet is very low in carbs (usually 20-50g net carbs per day), moderate in protein, and high in fat. This shifts your body into ketosis, burning fat instead of carbs for fuel.
How many carbs can I eat on keto?+
Most people enter ketosis at under 20-25g net carbs per day. Some can go as high as 50g and stay in ketosis. Net carbs = total carbs minus fiber. Start at 20g and adjust based on results.
How much protein do I need on keto?+
Aim for 1.2-2.0g per kg of body weight. Too little protein leads to muscle loss. Contrary to popular belief, moderate-to-high protein won't kick you out of ketosis.
