Radical Behavior has an excellent post on calculating what your ideal weight should be, and after looking around, found that there is not any hard calculation to make it easy. Calculations vary a lot, and I find that even the BMI calculations for the definition of being “overweight” tend to be too low for me at least when I consult with my doctor about it. I’m borderline line overweight according to the charts, but to anyone who notices my recent weight loss, I look fairly skinny.

Here’s some links to some ideal calculators:

• HallsMD Ideal Weight Aggregation (Hat Tip: Radical Behavior)
• MyFoodDiary.com Ideal Weight Calculator

RadicalBehavior.com has a handy formula to calculate the number of calories one should eat in a day.

To do a simplistic calorie content for me each day, I use the light activity setting and then add all the activities I do to get the count of all the calories I should be doing. For instance, if I run for 30 minutes, I add the calories I should I burn doing that activity to the calories calculated from that formula to decide how many calories total I should eat. It’s not exact, but it works for me.

I added a simple Daily Calorie Calculator here using RadicalBehavior.com’s formula. You can find it here.
