My java plug-in is being finicky so I can't see the link to the calculator. I agree with the main point of the linked article though - diet is more important than exercise in losing weight.
Recently, my own experience has been that once I upped my calories by 500 more per day and cut out half the exercise I was doing, the weight is steadily coming off. I'm not starving all day and I'm not killing myself 7 days a week, twice a day. I'm a believer!
Eating more doesn't mean eating whatever I want. The food I eat is good, wholesome, non-packaged foods. I'm not afraid of fats, I eat protein at every meal, I keep my carbs under 100 grams per day, and I'm not afraid to have a nightly glass of wine or a bowl of lowfat frozen yogurt with dark chocolate sauce for dessert.
