2-4-6-8!!

Tomorrow I am starting up on the 2-4-6-8 diet with a friend and we are having a sort of weight loss competition :) I'm going to keep it up for 8 days until my boyfriend comes back so I can show him my progress <3
OK so I am going to try to estimate my weight loss.
* 8 days on this diet = 4,000 calories
* bmr= 1,500x 8= 12,000
* daily exercise= 700 calorie minimum
700x 8= 5,600
Total burned= 17, 600
Calories burned - calories eaten= 13,600
Pounds lost= 13,600/ 3,500 calories per pound= 3.8pounds
:/ this isn't very much, but hopefully I will burn more calories through moving and exercising throughout the day.
