Well, first off, you’re not subtracting 500 cals. You can start there if you want; you don’t have to do the break-in week thing. Subtract it now.
Second, this is exactly why we said these things are individual and only you can figure it out. Start somewhere and adjust. There’s no easy way around it. Much depends on how fat you are, which is why some suggest to go by LBM. Problem is most people won’t go figure that out and if they do, they usually guess way off or use a poor form of testing so the number is really wrong anyway. (Or more popular, keep getting their bodyfat tested by different means until they get a number their egos can live with.) Hence our plain old bodyweight suggestions. It gives you a place to start, it’s easy to do, and the rest is up to you.
And as we’ve seen, even super scientific and drawn out formulas can be off. Most agree that Berardi’s Massive Eating/Don’t Diet numbers are way too high, in spite of the complex formula. So why even go complex? It’s all going to come down to experimentation anyway.
On a side note, it’s my observation that most people aren’t happy on a diet unless they’re starving and miserable. No wonder the Fat Fast is so popular. It doesn’t have to be that way. I think more people would be happy with the T-Dawg if we said to eat 900 calories a day. That way they’d feel like hell, starve, lose “weight” rapidly, have terrible workouts, regain all the fat, and shit once a month. Just like a real diet is supposed to be. [Mini-rant over.]
A closing tip: It’s okay to start a diet with too many calories. Just improving food selection will go a long way. Starting with too many is better than starting with too few. This is about long term health and looking good naked, not an ego satisfying but ultimately unsuccessful diet where you gain it all back. Leave that to the sheep.
