Hello all. I'm a male, 41 yo, 6 ft tall, weight 196 lbs and not much active at all (but this is about to change). Apparently my BMR is 1918 kcal per day (calculated with this bmr calculator). Now my question is - can I go lower than BMR and still do sports (running)? I would like to quickly lose some weight and after that change my diet and eat more than BMR rate is (obviously). Do you think this is a bad idea? As far as I was told, BMR isn't the lowest calorie needed since body can get energy from stored fats (in my case there's a lot of energy in there ). Can I do my body harm if I eat to less calories? I am not planning on doing this my whole life - just for now, until I drop some weight. What do you think?
