Carbs you don't really need to eat to live!

What of them you need, you can make it, gluconeogenesis and such. Proteins on the other hand...

Sure it’ll work but ketone bodies are acids c and the ver time you’ll end up with metabolic acidosis[1].

Diabetic Ketoacidosis is well documented in diabetic people[1], alcoholics, and in conditions of starvation[2] and the mechanism is the same. Ketone tests were developed for this purpose. Note starvation there, where the body starts using its own fats for energy. Here's a case report of it happening to someone on a ketogenic diet[3].

The body is designed to use its own fats for energy. All logic says you are talking about extreme conditions.

The body does that under circumstances of low calorie intake. The case study I posted shows a person developing keto acidosis just from following a ketogenic diet, it’s a well documented risk of ultra low carbohydrate diets if you bother to look. It happens frequently in people using these diets to treat diabetes, it just happens to be less dangerous than Type II diabetes.

It's about the ratios.

>Also, you do need some fat and carbs in your diet to, you know, live.

Absolutely agreed that fat and carbs are part of a balanced diet, but many foods and cuisines have poor macro nutrient ratios and, as hiddencost states, it is all about the ratios.

FWIW, I have been massively successful in eliminating "dadbod" and getting to a super healthy weight by using this diet for several years: https://www.youtube.com/watch?v=_nR1juKxIRM

The TLDR is ~.8grams of protein per pound of body weight, small portions of carbs and fat and half your plate should be low calorie vegetables.
