Is it safe to eat below your BMR?

Generally no. Eating below BMR can lead to metabolic adaptation (slowing metabolism) and muscle loss. Most health experts recommend eating at least your BMR even during aggressive weight loss.

Which BMR formula should I trust?

Mifflin-St Jeor is the current gold standard for most adults. Harris-Benedict (revised) is also popular but can slightly overestimate needs for sedentary people.
