Lettuce wraps? Yes. Wrapped in a tortilla or other bread product? No.
Here's what you eat. Ready?
Breakfast is 3 eggs, bacon.
Lunch is a pound of beef. Ground beef is okay. Make sure it's a full-fat cut, no lean shit. Rare.
Dinner is another pound of beef.
Drink all the fucking water. 80 oz a day is a bare fucking minimum. 120 oz is better. The process your body uses for converting fat into energy is extremely water intensive.
That's it. That's the whole diet.
Some people add greens for fiber, but you really don't need to. Eating nothing but animal products there's almost no waste, so you'll shit maybe once a week. Huge time saver.
Three days in your body will panic, you'll be hungry as fuck and stressed and bread will sound SO FUCKING GOOD to you. Push past this. Be a man. Every time you think about eating carbs think "that's what a fat sack of shit would eat." and go about your day.
A week in your hunger vanishes. Hunger, as you have experienced it all your life, is ENTIRELY a product of your body running out of carbs. If you are always out of carbs, you NEVER get hungry.
About a month in you get the "keto flu". That's when all the bacteria in your gut that metabolize plant matter finally give up and die off. You'll feel it in your mouth too, since the bacteria there will have a simmilar die-off. This makes you feel like absolute shit, I won't lie, but it only lasts a few days. Call in sick.
After you're over the keto flu, that's when you feel like a fucking metahuman. You become focused in a way you've never experienced before. Your energy is absolutely boundless. You DO NOT EXPERIENCE MUSCLE SORENESS THE DAY AFTER A WORKOUT. It just doesn't happen. Honsetly I have no idea why. Your teeth will never look better: you still need to floss to clear strips of meat and shit, but brushing is no longer required to keep odor down or bacteria at bay, zero plaque buildup, because no sugar is feeding the bacteria that causes those problems.
