Muscles don't keep you warm in freezing ocean water! Blubber does that.

...Man I wish I had a bulletproof excuse like that.

I choose to imagine you're the polar bear version of jason statham's character in every movie he's ever done.

I mean, I sure do like pizza and beer. But my personal experience is that low carb diets are awesome. I've done the keto diet probably about half a dozen times in my life, and (after ensuring my electrolytes stay balanced) it has consistently given me positive results.

I first tried it with the notion that fat and protienn were satiating, and therefore it would be easier to stick to a calorie deficit. Simple. I disregarded all the people who talked about "more mental energy" or whatever bullshit - I just wanted to lose fat. But the results blew me away.

Without counting calories and while eating lots of deliscious food, I lose fat basically without trying and get a six pack. My athletic performance isn't diminished, and my hunger levels drop noticeably. Hunger itself feels less important, and my emotions in general become more positive - I am more likely to feel happy and grateful and to fall into flow states, and setbacks and bad moods bother me far less. I fall asleep easier and sleep more soundly. My skin looks better. And these effects persist as long as I am on the diet - it isn't just "losing water weight" or whatever.

Why does it do this? I dunno. Just does. Typically I eat a diet with lots of veggies, beans, some meat, and the occasional pizza and beer night. But comparing a whole foods keto diet to a standard american diet of processed junk food, I'm gonna go ahead and say that keto will come out far ahead, and I'm not gonna let the perfect be the enemy of the good.

Carbs are a great delivery mechanism for calories. So good, in fact, that the caveman part of your brain really insists on eating as much of them as you possibly can. Some people have problems getting the caveman part of their brain to shut the fuck up and consequently they eat too many carbs. They do that for so long that that end up having a foot amputated and die young of kidney failure.

Empty carbs, the carbs most people think of as carbs, are a terrible source of nutrition and are the primary reason most people are fat. Bread, skinned potatoes, pasta, corn, and sugar. That kind of shit. You know, the delicious carbs. The carbs that the caveman part of your brain really insists you eat more of. Cutting those from the diet helps regulate hunger for people who are calorie counting.

You can get 100% of your daily carbohydrate needs from green vegetables. You can do that pretty easily because you don't actually need that many carbs.

That said, if you have a healthy relationship with food, are at a healthy weight, and your bloodwork doesn't show any signs of metabolic syndrome or heart disease, keep on keeping on. Congratulations, you can eat whatever you want. Just understand that being adult, especially an adult in the US, that can tick all of those boxes is pretty rare and other people do have issues they're trying to correct, and have to keep an eye on their diet. Generally, that means cutting out the fun carbs even if they're not doing keto.

They're really not, but not everyone needs them.

If you're bordering type 2 diabetes and carbs just make your blood sugar shoot up and crash down, reducing or eliminating carbs can get your shit back in check without medication, and make it much easier to reduce your calories (since you don't feel compelled to stuff your face again because of shaky hands)

Carbs/fats/proteins are just the delivery of calories.

If you’re wondering we burn them in the order of protein > carbs > fats. That’s why we store them as fat, eat carbs before an athletic event, and eat protein after one.

I have diabetes and I have this guide to carbs and healthy eating. It’s 45-60g carbs per meal I think, and the portions are hilarious. It’s like 1/100th of a bagel or something.
