I’ve always used the method where you figure out your BMR and then multiply it by a number representing your activity factor to give your daily maintainence calories. Although within this method there are various formulas, they give results which are pretty close together.
Recently I’ve read a few articles and books where the authors just say “10-15x Bodyweight for fatloss” and “15-18x bodyweight for weight gain”. Even using using the higher end of the weight gain formula it only matches what I usually use for my maintanence calories using the original method.
Has anybody else come across this? I know it doesn’t really matter but i’m just curious how can there be such a huge discrepancy. One training article actually put me at 1600 cals a day while lifting 3x a week and HIIT 3x week, even for fat loss this is near starvation! I thought no one was supposed to go below 1500?
