Закаливание, тумо и прочая морозоустойчивость

Чем глубже кетоз, тем дольше задержка дыхания.
Были шоколадки (вне 99%, а, допустим, были блюда 50/50 БЖ и любой другой уход от классики - 2 минуты), более тщательная кето-диета - 3 минуты.
Подумал - моя ли это "выдумка" или есть данные.
Данные есть, в принципе ничего нового. Примерно эти же данные приводит Д.С. в ветке кето-диеты.
Нам нужно меньше кислорода, меньше СО2 вырабатываем.

Carbohydrate depletion.

Prolonged periods of physical work deplete the carbohydrate stores (glycogen) in the body, which forces the body to compensate by increasing the rate of lipid (fat) metabolism. When the human body burns fat to produce energy, it uses 8% more oxygen than when metabolizing carbohydrates. Also, 30% less CO2 is produced by fat metabolism. Thus a breath-hold hold diver who has depleted the glycogen stores will become hypoxic faster, and, making the situation worse, the CO2 driven stimulus to breathe will be delayed. A dive that could safely be performed in a rested and well-fed state may be dangerous after a long day of exertion from diving or land-based activities (50). Carbohydrate intake has been shown to reduce breath-hold durations, due to more rapid CO2 generation (because of a higher RQ) in subjects who had fasted for 18 h, suggesting that that the risk could be reduced by proper carbohydrate intake and that breath-hold diving on an empty stomach may be dangerous (48).
