Getting your heart rate HIGH is what blasts those calories.
By consuming 2000-2400 calories a day: After a workout, that doesn't leave you with much of a calorie deficit.
Women seeking weight loss should probably consume net (Net: calories consumed after exercise) 1800 calories a day maximum, and 1200 minimum.
If it were me, I would decrease your consumed calories each day to 1500 - 1750. It will speed up your results, and if you eat nutritionally dense foods, you won't be as hungry as you think!
Another tip I have for you.. If you exercise often, I recommend:
Breakfast: Carb, protein, vegetable
Lunch: Carb, protein, vegetable
Snack: Fruit / vegetable / dairy etc
Dinner: Protein and vegetable, NO carb
Also, try not to eat after 6 or 7 pm, and ALWAYS eat breakfast!
Don't get discouraged
