Sodium content varies by plan. On average the meals are about 300mgs-500mgs per meal, well within recommended guidelines.
All Keto meals have been carefully crafted to meet the criteria of a ketogenic diet and are therefore around 800mg per meal. You may be losing more sodium when in ketosis - potentially by a decrease in insulin from eating fewer carbohydrates. Increased intake of sodium while on a low carb diet can help some of the negative symptoms people may encounter when starting the ketogenic diet - including light-headedness, fatigue, headache, and hunger. It can also encourage you to drink more water which can furthermore help with these symptoms.
