1. Calculate the minimum amount of calories that you need to sustain regular activity. (You need to re-calculate this per week or bi-weekly)
2. Calculate the amount of calories that you can burn weekly.
3. Calculate the amount of calories from your daily food. (Start doing this by replacing your regular food with low-calorie food. Try food that is low on sodium, low fat, no transfat food, say yes to beans and multi-grains food. Drink 3,4L water daily when you are on diet. No soft drink include diet coke or ice tea. )
item 3 - item 2 - item 1 = calories that you lose per week.
1 pound fat ~= 3500 calories
你boss只靠吃时不可能减那么快的,除非做手术,她/他应该是下班以后去gym的,有能力/时间的话每周休息3天recovery,其他时间早上去一次,晚上去一次gym. 体积大的人要减下来需要付出更多的努力,可能只是自己不愿意在别人面前表现的太痛苦.
