    I think it’s very misleading to use a simple calculation to determine the number of calories you need in a day.

    I weigh 238 pounds which should give me 3094 calories per day. I only eat around 2000 calories per day and run 5 or six days per week. Theoretically I should be losing weight every week. I don’t. I struggle to maintain my weight.

    I have worn a heart rate monitor that determines calories burned for a full 48 hours and it came back with 2500 calories burned in two days! I cut my calorie intake down to 1200 calories and I started to lose weight (slowly).

    Everyone is different (my wife eats for England, never exercises but maintains her weight). Don’t be fooled by simple calculations; the human body isn’t that simple!!!

    Great website. Keep up the good work!
