An egg fast is a short term (3-5 days) way of eating that can help individuals jump in (or back into) a state of ketosis (when the body adjusts from burning glycogen from carbs to burning fat from food and the fat stored in their body). It is essentially a ketogenic diet in it’s simplest form.
There are many variations on the guidelines for the egg fast, but typically, the meals and snacks consist of only eggs and healthy fats, including full-fat cheese.
The two basic rules are:
1. Eat at least 6 eggs a day, along with a teaspoon of a healthy fat (like butter or coconut oil). We typically just eat when we are hungry and stop when we are full. Some days that looks like 10 eggs, others it might even be one.
2. Six ounces of cheese are allowed.
Everyone’s egg fast experience will vary. We have done several rounds of egg fasts, and with each round, we have learned what has worked, and what has not worked for us personally. Modifications we have made are allowing zero calorie/zero carb sweeteners, herbs/seasonings 1g net carb or less, fitting in intermittent fasting, and drinking at least 1 gallon of water a day.
