In my last post, I told users that I am writing a calorie script – this includes a weight-loss/gain calculator, and the ability to track progress. However, I’m running into a snag, as there’s a lot of controversy surrounding the best way to calculate the needed daily calorie intake to hit your target weight in a set time period. The following are all formulas I’ve run across while researching this.

One More Bite:

Desired_Weight x ALM

Peer Trainer:

(Curr_Weight – 10) + (Height_Inch x 4.6) + (Age x 4.7) x ALM

(Wednesday, December 02, 2009, 9:37 AM) Peer Trainer:

Target_Weight x 10

(Thursday, March 30, 2006, 8:35 AM) Peer Trainer:

((Curr_Weight x 11) – Calorie_Min) x Target_Days = a

(Target_Loss_Gain x One_Pound[3500 calories]) – a / (Weekly_Work_Out x Target_Weeks)

BMI Calculator:

Curr_Calories / 20%

*ALM = Activity Level Multiplier

If anyone has other references, suggestions, or knows an accurate formula for weight-loss/gain, feel free to leave a comment below.
