Is this how the math works? It feels weird - I remember recommended intake for me being around 2000 or something (for a regular 30y.o semi-active male), which would make this require getting into negative calorie intake.
I know literally nothing about this, though. Or are the 70 000 calories factored from how much a body burns? So, it’s basically impossible in 30 days for someone whose daily burn-rate is lower than 2300, based on his age/sex/activity?

Basically for every 3500 excess Calories consumed, your body stores about 1 lb of fat, and for every 3500 Calories burned, you lose about 1 lb of fat. If your intake is equal to your output, there’s nothing being stored.
You would have to get that burn rate 2300 Calories above the intake rate, so yeah if your daily output is 2300 Calories, you’d have to eat literally nothing for 30 days to lose 20 lbs.
