Is it safe to assume that 6 years later, this is still an accurate way to determine BMR/TDEE?

To add to POBs response, you can use 3 or 4 different formulas and should be able to average or get a better ballpark number for a starting point. And it is just a starting point. Adjust up or down every few weeks as needed to achieve your goal.

Thank you both. Looks like no matter who’s calculator I’m using, I should probably bump my cals a bit.

I’m jumping in without reading the full thread but my advice is to treat any number as a starting point only. As Bricks mentioned, it’s all about the adjustments.

If you have an iPhone, hook MyFitnessPal up to Apple health and the HappyScale app. Assume 3500 cals equals one pound of fat. (This isn’t completely accurate but works well enough)

Whatever you end up gaining or losing after a week you can increase or decrease your weekly calls by the necessary cals to achieve your goal.

Obviously building muscle throws this off but you should have a decent idea of how much you’re adding in a week. (Probably not much compared to fat)

What your body does with the food is a better gauge then any formula.

A couple of possibilities:

You're not tracking your calories accurately

You're losing fat but holding water for dietary or hormonal reasons

You haven't been dieting long enough to see results

You've vastly over-estimated your TDEE

Or you're a true genetic outlier for whom more aggressive/specific methods are necessary.

The last option is BY FAR the least likely.

i used the equation at the beginning of this post and came up with these results. i have been dieting on and off for a year nothing really seems to work...
