So it’s day three of my keto egg fast and I’m down another pound this morning for a total loss of 6 pounds so far. I know it’s mostly water weight but I don’t care – it’s still nice to get excited about stepping on the scale every morning again. It reminds me of when I first started keto and the pounds just melted off! It’s very encouraging after such a long dry spell of not losing!



Also of note, I have tons of energy! My mind is clearer, I’m not tired, I feel great overall. Yesterday I did a bunch of yard work at a friend’s new house, and I never felt like I ran out of steam.

My body is obviously getting everything it needs from this keto egg fast, unlike other fasts I’ve tried and read about, where you are totally crashing by the third day. As a reminder, I’m supplementing daily with magnesium, potassium, and making sure I’m getting plenty of sodium as well.


What I Ate on Day Two of my Keto Egg Fast

8 eggs

2 Tbsp butter

6 Tbsp sugar free mayonnaise

1 Tbsp MCT oil (in my bulletproof coffee)

4 string cheese

1 oz sharp cheddar

36 oz La Croix sparkling water

102 oz spring water

16 oz diet coke (I WAS WEAK, GAH!)

So I’m sure you’re all dying to know –  Do I hate eggs yet? Surprisingly the answer is no. I’ve eaten nothing but eggs, cheese, and butter for three days on this keto egg fast, and I AIN’T EVEN MAD ABOUT IT.

I think the strategy to avoid egg burnout on an egg fast is to change up how you eat them so that it doesn’t feel like you’re eating eggs at every meal.

And there are so many great possible combinations to be had! I’ll be posting more keto egg fast friendly recipes here throughout the week, and they will all be used in the keto egg fast meal plan that I’ll post at the end of next week.



This egg fast custard was the perfect way for me to end my first day of egg fasting, and I plan to make another batch tomorrow. Since I’m avoiding heavy whipping cream for this egg fast, how to get the right texture was problematic.

I finally settled on a mixture of eggs, cream cheese, and water to get the right consistency in this egg fast custard. It was slightly grainier in texture than a typical silky custard made with cream, but definitely still custard-like – and a REALLY nice break from the heavier consistency of cooked eggs in other forms.



You could eat this egg fast custard without the caramel sauce, but why would you? It tastes amazing, and for the purpose of your egg fast the added fat from the sauce is important to get the right ratios.

I flavored this egg fast custard with this caramel flavored extract that I found at our local Walmart, but you could do maple, or other flavors as well to change it up a bit.

By the way – this sauce would also taste amazing on your keto cream cheese pancakes.
