I have a low carb food list here that gives you a full list of all the foods you can eat, and the net carbs in each. You can also sign up above to be notified about the meal plans, which are a great way to get started. Hi Mea, In general I don’t recommend a cheat meal or day on a keto diet.A small 2017 study involving athletes found tiredness to be a common side effect of the ketosis diet. Participants typically observed this during the first few weeks. Electrolytes include calcium, magnesium, potassium, and sodium.
