Please stop hyping sardines lol ... I buy them buy the case, over the past few years i'm finding my favorite brands are frequently out of stock and prices are creeping UP

I'd recommend sardines + eggs. Sardines alone will get you hungry unless you eat insane amounts.

Hey Thomas, it would be fun to see you do a video where you are actually doing the sardine challenge from day one through three and test your own ketones/glucose.

I'm a 63 yr female who cycles in/out autophagy who is in the middle of a 72 hr sardine fast. Since Dom is who I learned it from & I do it often, ie:eat low carb high protein for 3-4 days then nothing but coffee & water for 36 then go to Sardines until my GKI is 1:1. I don't get hungry, I've never looked or felt better and my energy levels are off the charts. I have low body fat but muscle and that's important at my age.

That has become impossible since sardines NOT in seed oil have become very hard to find (I suppose because of the avalanche of videos like this one)
