What if I only ate protein?

What if I only ate protein?

I mean just
-chicken
-nuts
-eggs

Protein is a bad source of energy. You'd fatigue easily.

Nuts and eggs both contain fat

You'd have to eat nothing but egg whites

you'd probably get some health problems

you would be considered mentally challenged.

Well I don't mind that but why exactly would this be bad.

Maybe I misspoke. I didn't mean Protein only because that'd just shakes. I mean protein heaviest or protein richest.

At least throw in some Oatmeal and steamed Broccoli

Not on Keto lol. More energy on eggs and bacon than on bread and cereal.

It'd be absolutely fucking terrible if you got no fat. Pioneers used to get horrible muscle wastage if they stayed on a diet of lean protein for extended periods of time.

You could actually die

Yes my boy , try to do any kind of real exercice for a sustained period of time without carbs .
