Not to pick, but usually calorie counting only really works if you are precise with it (this includes accounting for every beer or the milk you add to your coffee everyday). Another thing to consider, if you are on the obese side of the BMI scale, unless you are 5'2", 1500 kcal is too little specially if you are doing spinning + badminton.

BMI is not really accurate on the individual level. Most athletes will score on the 'overweight' range for example while athletes that play in weight division sports will be in the 'underweight' category a lot of the time (I was for example, but I doubt anyone would consider me underweight at the time).
