100 g of protein = 400 calories (4 x 100).
100 g of carbs = 400 calories (4 x 100).
40 g of fat = 360 calories (9 x 40).
Total = 1160 calories.
You're way low
for 1500 calories. You can eat more!
If you want to skip all this
math, a great place to go is Fitday
- a free web site that allows you to track what you eat and adds up all the calories and grams of this and that for you. I couldn't manage without it!
