1800 to 2000. I am still losing, probably about a pound per week right now. More importantly to my mind, on this level of calories: I am satisfied with the variety and taste of my food, getting plenty of excellent nutrition, not driving myself insane over calorie counts, have enough energy to do all the physical stuff I want to do, sleeping well, and feeling super-healthy.
2000 cals a day, 2250-2300 on days I do my strength training (it basically covers the PWO shake I take). I'm still losing weight on those levels (and long may it last)!
Just thought I should add that I started with a lower calorie range at 358 (1600-1800), but my weight loss was inconsistent and I had a hard time sticking to it. Later, when I started lifting weights I actually raised my daily calories, and now I kind of like them here. So I just try and be more active overall.
I started out at 2000 a day, but found that when I was eating "clean" I just didn't eat that much. So now I'm looking at 1600-1800. Probably once a week I go above that. And once or twice I get to the end of the day and find it's only about 1400. But I think that cycles like that are normal, and helpful to keep the body from adjusting too easily to where I am.
Between 1500-1600 and this week because of challenge from my weight loss group I'm keeping it almost right at 1500 calories. I'm curious to see how it works out for me.
